4:06 - The most useful thing I have heard after watching about 12 knife-sharpening videos. Thank you. Width of the knife divided by 4 . tan( 15 degrees ) = 0.27 or about 1/4
He used to upload like one or two videos every few months (sometimes longer) before the lockdown happened. Now he uploads at least a few times a week and puts out better content than a lot of other channels.
I swear every time I watch a Kenji video I add something new to my never-ending list of "things I'll buy when I get rich" haha. Knives look gorgeous. Great video as always, man.
There's a good tip on finding angles by using a sharpie to fill in the edge up to the bevel. Do 1-2 passes in the whetstone, then take a look. If you're too high, it'll just get rid of the tip of the edge, if you're too low it'll just get rid of the "shoulder" of the bevel and not the edge.
Gave this a try after watching and all I can say is I’ll never have a dull knife again. As a total noob I was able to get my knife sharp enough to shave. Thanks.
A nice and easy way to flatten your stone at first, before you pass it with the fixer, is to "divide" the wet stone in nice little squares with a pencil, then use the fixer. When all the pencil marks are gone, your stone is as flat as you'll get with the fixer and ready for sharpening.
I've watched so many sharpening vids and they all leave something out, this is the first one where as someone who has never done it before can get it. Also you record it over your shoulder! Everyone records it facing the opposite way making it SO difficult to replicate.
Knife sharpening was a skill I refined earlier in the lockdown! I even brought my kit when visiting my folks and in-laws (partly for my benefit too =p). Japanese Knife Imports has great videos for anyone wanting to go more in depth on technique or tutorials for different knives. Good stuff though, Kenji!
wtf. i watch your channel all the time and had just bought a couple wetstones today to sharpen my knives and came to youtube for a tutorial....... this simulation is breaking down.
Great primer on using a whetstone to sharpen high-quality kitchen knives. As always, Kenji, thank you. And a special thanks to Barney. Stay safe, be well and take care of those you love.
A bit of advice for you folks who are nervous about getting started-don't be. Get one of your cheaper knives and tilt it up until the cutting edge is on the stone and just get started. Take it slow and get the feel of it. You really can't do it perfectly at first. If you get the knife somewhat sharper, you're doing great. If not, don't worry, you're not alone. Watch another video or two and get back on that horse. As you get more practice you'll do better and it'll be more satisfying. It's a great feeling to keep your knives sharp.
I was just thinking it was time for you to do a video on this. Sharpening with a whetstones is so much fun when sharpening your knives. Just put on some music and spend time to properly take care of them. The only knife I don’t use stones is my Yaxel super gou 161. I’m too scared I’ll ruin it and bought their tool (which is still stones but with rolling guides). Ps, thanks for the baking soda tip for baked potatoes. So crunchy! Edit: A good tip when flattening the stones is drawing a bunch of lines with a pencil both horizontally and vertically. Once they all disappear it is ready.
Barney brought tomatoes and bread in that bag. In my head I like to imagine Kenji's bacon friend came over and they all enjoyed some BLTs after shooting this vid
Not to ruin the picture in your head, but I headed over to Wursthall after we shot this video--which I still count as a win! I highly recommend the Chorizo Verde.
Hey I bought that same strop a while back. Made it simple instead of trying to find the right leather and such myself. Helps me keep a wicked edge on my harder knives for sure. Good techniques.
Great video, Kenji! Would you consider doing a video on oil smoke points and grease fires? I just saw a post on the SE subreddit of someone who was trying to get wok hei and started a grease fire. My partner (who also loves your videos!) also started a grease fire in our house years ago when he was first learning how to cook 😬 because of that I’m always pretty conservative with heat and empty pans.. but I’d love to be more informed!
How do you feel about using a Sharpie or other marker to color the edge and check your progress as you sharpen? Is it helpful to get the feel of having the right sharpening angle or seeing which parts of the blade you may be missing?
Your comments about honing rods are interesting. My local knife store sells primarily Japanese knives, teaches whetstone sharpening classes and recommends using a ceramic honing rod on all their knives! Wonder what the deal is...
Travis Schwantje honing rods aren’t terrible, you just have to be very careful as hard steel is more brittle than you may be used to with western knives where you can really wack them on the rod without much risk. Ceramic rods are a good choice because they are lighter and less likely to smack into your knife blade. But a strop is the safest and easiest choice, unless you have a bunch of mixed knives and just want to keep one honing rod.
Ceramic honing rods works very differently than the traditional steel honing rods. Ceramic is dramatically harder than the steel of the blade, so you are abrading the edge when you hone on a ceramic rod. Therefore, it's more like sharpening rather than "honing" in the way a steel rod will. For that reason, I don't like it. If I finish on a 12,000 grit waterstone, honing it on a ceramic rod that is dramatically more coarse is going to change the edge characteristic. However, steel rods generally are not as hard as even the most mainstream japanese chef knives in VG-10 steel (I personally haven't seen any japanese kitchen knives hardened to less than 60 HRC) so honing with those won't be super effective, and then there is also the concern of banging the edge against the rod as Kenji mentioned. But also as Kenji mentioned, a strop is generally superior to both once you get the technique down and don't accidentally round the edge. I have a honing steel from Shun which theoretically should be harder than their VG-Max steel (~61 HRC) and it seems to actually realign the edge well, aka it brings back the aggression to an edge that might be rounded or overbuffed from bad stropping technique.
Wish I had a river near me. Some of those stones work really well. Just gotta find a nice one. They don't remove metal really fast but some of them are good as finishing stones.
Kenji, if you start with the point below the bolster on the right side of the stone as you're showing, it is almost immediately removed from the grit when you start the draw, and thus gets near-zero tapering (and thus near-zero sharpening). I doubt that is what you want. The point below the bolster should start the draw near the upper far *left* of the stone, finishing with blade tip just exiting the lower far right. And of course, reverse that for the other side. Failure to do this is one of the reasons over time you see a "droop" near the bolster on very old knives.
A little advice for you Kenji, try sharpening in sections. For one thing, doing so will allow you to keep pressure over the stone at all times, a substantial improvement over trying to press on the end of the blade and the handle. Pressing on the edges, as you do here, is much harder to control, and could distort the steel during sharpening. Also, there's a lot of misinformation about sharpening angles around on the internet, but the two largest German knife manufacturers, Wusthof and Henckels, factory sharpen to 14 and 15 degrees per side respectively. Believe it or not, knives made with very hard steel (much harder than VG-10) will frequently be sharpened to 8-12 degrees per side! Also, you mention that a single bevel knife should be sharpened 90/10... unfortunately, this is wrong. The flat face (or more typically, concave face) of single bevel knives should remain flat. Look up uraoshi sharpening for more info! If it so happens that you have a yanagi ba that you've sharpened the back of (and it sounds like you might), I have a little shop in oakland that does repair on knives. I'd be happy to try to help.
Very excited that this dropped just a couple days after i bought my first forged knife. Not as nice as the KAN stuff, but this video has some good lessons. I didn't know about the honing rod issue.
for the finnishing pollish you can use leather belt and you rub the knife against it. Shines more and also cleans all the dirt. Is common practice here.
"You have to know it's sharp" like you would do when grabbing a knife :D But agreed, even average market knives start to shine if you learn to sharpen them. It made cooking so much more enjoyable. Like imagine just gently driving the knife through a tomato instead of pushing or sawing, or doing a rocking motion on a carrot that is hard and round and difficult to handle, and the knife just bites it and keeps it steady and cuts through. My kitchen accidents also saw a big diminish after learning to sharpen knives.
Dude.. you're paid to cook! if your place of business uses a knife service that replaces knives then do it! though I would still do a lot of touchup since they will be simply ground on a wheel and replaced over and over. and those knives will be butter soft. if you can get it done with what they provide I say go for it. if what they have just sucks then I would bring my knife roll and take it home with me everyday. a grinder sharpened knife will be sharp for a while and is good for basic task.
@@trenvan5546 my last job there was a gentleman who came by once a month to sharpen knives but the knives would sometimes come back to you even more dull.. he would also take off a lot of material. practice makes perfect i guess and i'll just have to practice on my beater knives :)
Okay, thank you for this, I learned a lot and glad I’m not going to screw up my Kans when I get them! I’ve been using a honing rod with my first chefs knife I got not realizing it could damage it (pretty sure it’s a hard steel). Heading over to Amazon to buy some sharpening steel before everyone else buys everything after watching this!
Raising the blade 1/4th the height sure enough works for 15 degrees because the tangent (opposite over adjacent) is about 0.25. So raise the blade 25% of the height for 15 degrees. A three to one ratio is actually 18.3 degrees
what lightfire33 said, but if you just follow the existing angle it's your easiest bet. E.g. try the sharpie method. Paint the edge black with a sharpie and try a few strokes and see whether you're matching the original angle. Also take note how that feels during sharpening and the sound on the whetstone. It changes as well if you match the angle.
One thing that I learned from someone who went as far as to put a knife under an electron microscope is that the common notion that a steel honing rod "realigns the edge" is a common misconception. What it actually does is remove a tiny amount of steel material as to create a micro-bevel, thus removing any portions of the edge that have been flattened or malformed and restoring the knife's keenness. (Google: "Science of Sharp, Steeling" to find the article). Another bit of advice I've gotten in terms of knife honing is that if you really want to use a honing rod with a Japanese-steel knife, use a ceramic rod. While a honing steel may or may not be harder than the steel in your HRC60 Japanese knife, ceramic is guaranteed to be harder than any knife, and you can verify its removal of material by the dark streaks of swarf left on the rod. Generally though, a leather strop with a fine abrasive compound like Kenji demonstrated is preferable.
You know, for a little while now, my household has been saying "when COVID is over we're going to have our knives sharpened". Maybe we'll buy a whetstone set and do it ourselves!
First of all, thank you for letting me know the 2 sided stones are cheap. I will definitely look into new ones! Second, you didn't finish explaining when to use a honing rod (steel). Which knives would it be okay using it on?
i would love to know what you find that works that's inexpensive! got a few knives that are begging for a sharpening but i dont have the pockets to drop 60-80 bucks on some stones to rarely use them
Hi Kenji - I'm glad you're covering this topic and mentioning that we should investigate different methods to find what works best for each person. I recently made some knife sharpening tutorial videos using techniques I learned from sharpeners in Japan. Thanks.
diamond stones for life :). higher price up front, but theyre less messy, require no surface prep, dont need to be soaked, and they last longer i just use them dry, and then wipe them clean with a bit of rubbing alcohol when im finished with it
While I don't have proper strops I literally use an old leather belt. Along with my 500-800-1000 grit whetstones I've had more fun cooking than ever before
I think they kind of addressed it in the video, but would it be a mistake to purchase an expensive knife as my first kitchen knife and sharpen it (when it gets dull)? Or should one first try using and sharpening cheap knives before moving on to an expensive one? I am about to purchase my first knife (will be living by myself but I have used chefs knives for many years but not very good/sharp ones) and I'm considering a Zwilling Professional S, which I see as an expensive knife. Should I purchase a cheap one first? Anyone have any thoughts?
Thank you for this video. I have a stone for my Misen knife and also have a rod. I've been afraid of the stone but think I can manage after watching this
Using your book "the food lab" to raise up your gopro was next level product placement

“...easiest way is to just use come basic trigonometry.”
So I’ll just guess. Got it.
Eh, for a chef's knife, I just lift it by the width of half my thumb
A paring knife I lift by about 1/4 of my thumb's width
@Ryan Gilmore yeah but you still need some kind of baseline. If you go purely by where the edge currently is, your bevel angle will drift over time
But kenji does teach it! 1/4 of the width of the blade gets you 14.5 degrees!
6.49 DROW RANGER tldr

Whetstone knife sharpening has to be one of the most meditative things I do regularly outside of cooking itself
Literally two days ago I sharpened all of my knives, and I love doing it.
Malachi Merriam I’m really looking forward to doing it this weekend myself! My blades need a little love
Agreed
Sharpened my everyday driver least week, I secretly wish I did it more often because of this exact reason
Mark York same here. Just gonna have to use a strop everyday to get my fix

Finally! The video I’ve been waiting for!! Thank you!!! Love it
This is going to be a game changer!
I've always been told to run the knife across a honing rod without pressure. Regardless of the steel.
Your comments about honing rods are interesting. My local knife store sells primarily Japanese knives, teaches whetstone sharpening classes and recommends using a ceramic honing rod on all their knives! Wonder what the deal is...
Just please use very light pressure. You should be fine.

@@kankitchen Thanks! I really appreciate the advice
I actually purchased the basic kit from Kan! Can't wait to get them!
Pro tip : just pick a flat stone from the river it works a lot better than you would think. I found one that was arround 2500 grit
Wish I had a river near me. Some of those stones work really well. Just gotta find a nice one. They don't remove metal really fast but some of them are good as finishing stones.

Very awesome, practical video! I also like that outro with your books and links listed!
I so needed this demo, thank you! I do wish you'd done a before & after with the tomato slicing, but maybe on another video someday.
Why do you go back and forth (both directions) vs the one away direction when sharpening the knife on the stone? Does this matter or is it preference?
I have touched up my Japanese knives (Shun ,et al) with a ceramic hone for at least ten years. No problems and much quicker than stropping.
A little advice for you Kenji, try sharpening in sections.

how do you go about sharpening in sections?
Thank you!! I read your article on serious eats, and ordered a stone, but I've been too intimidated to try. These additional visuals are helpful.
Try warming the strop leather with a hairdryer before rubbing the polishing compound into it. You'll get a nice thin, even coating.
Kenji is so supportive of his friends
Very excited that this dropped just a couple days after i bought my first forged knife. Not as nice as the KAN stuff, but this video has some good lessons. I didn't know about the honing rod issue.
Spent half an hour with a Mino Sharpe on one of mine just now and it's stll blunt. I've got them attachments too!
Very enjoyable video. Do you keep your whetstones in the water bath between uses? Do you clean them after sharpening each knife?
For anyone who wants more info about this, japanese knife imports has a really good RUclips playlist on all the little details of sharpening

Is there anything you have to do differently when sharpening a meat cleaver? Or any other knife meant to go through bone?
those will get dull regardless
much larger angle, no less than 30 degrees. (you don't need a razorblade to cut bone, you need strength e.g. more steel)

What's all the water bottles off to the side there for? You making a soup later on?
I thought I could grind out a food pun about knives here..
But I'd probably get too many *cutting remarks.*
Edgy humor, I love it!
You're whetting my appetite for puns.
You must have a sharp mind!
This joke left a pretty bad tang on the palate
Chris Murphy -perhaps I can try to bolster your confidence in our humor.
Kenji if i could only buy one whetstone grit, what grit would you recommend?
Depends on the steel but I’d say 800 or 1k for most uses.
@@JKenjiLopezAlt Oh I just saw this reply. Thanks for taking the time to answer!
Hi Kenji -- how often do you need to use a stone fixer? After every sharpening session? Thanks
It's not really necessary after each session. When your stone gets noticably concave you may flatten. Flattening too often is a waste of your stone.
What whetstones do you have?
I notice your stroke doesn't involve the very tip. is this intentional? or do you work on the tip separately
ive been waiting for this video! thanks kenji:)
While I don't have proper strops I literally use an old leather belt. Along with my 500-800-1000 grit whetstones I've had more fun cooking than ever before
I think they kind of addressed it in the video, but would it be a mistake to purchase an expensive knife as my first kitchen knife and sharpen it (when it gets dull)? Or should one first try using and sharpening cheap knives before moving on to an expensive one?
I am about to purchase my first knife (will be living by myself but I have used chefs knives for many years but not very good/sharp ones) and I'm considering a Zwilling Professional S, which I see as an expensive knife. Should I purchase a cheap one first? Anyone have any thoughts?
Any updates for home cooks to sharpen their knives?
Strategic placement of your book. It also doubles to help prop up your camera stand to the right height.
King Deluxe 300 can crack if you soak it. It is a splash and go, in the Neo line. The red Kings are soakers.
Do you wet the towel before hand so it doesn’t dry out your stone?
I know that King is a recommended whetstone brand, but any suggestions for a flattening/fixing stone?
Naniwa makes a good inexpensive flattener. You can tell it by the diagonal grooves across it. Usually about $25 or so. Works well.
this is my favorite trevor dunn piano cover wow
What are your thoughts on the magnetic bars to hold your knives. Does it hurt them.
They are good! At least the ones that are magnets in wood. Metal racks I’d avoid.
I love the knife block you have for your knives. Can I ask where you found it?
What whetstones do you have? Are they all king?
Thank you for this video. I have a stone for my Misen knife and also have a rod. I've been afraid of the stone but think I can manage after watching this
