Naoto, thank you for this excellent tutorial. I've learned so much!
Thank you!
Ive just found your channel & im finding your sharpening videos very helpful. Thanks Naoto.
Glad I could help!
Thank you Naoto - Very helpful. I look forward to your Friday sharpening chat.
Thank you for watching buddy! See you on Friday, we'll be talking natural stones.
Extremely helpful video. Thank you so much.
Happy to hear it, thank you for watching!
Best sharpening video on RUclips
Thank you!
Been watching for a few weeks now and very pleased to actually learn something. Love the format and your teaching skills.
Happy to hear it!
I’ve have many knives but I’ve yet to master to stone. I practice on cheap knives to learn the angle
Great way to learn!
Ichi ban Naoto!!! Love your videos!
Thank you!
excellent video! thank you!
Thank you!
Best sharpening video on you tube.
Thanks so much!
Thank you for sharing your traditional wisdom, you are a very good teacher.
Thank you!
Use plastic angle guides, about $10 bucks. They're little plastic chips that have a slot for a rubber band to hold them onto your whetstone, so you can re-check your angle at any time. They come in sets, angles from 10 to 20, IIRC. You can stack 10 and 15 if you want 25 for a cleaver. Holding an angle is like learning to ride a bicycle. At first, it seems impossible and you fall a lot unless you have training wheels. After m-a-n-y hours of practice, you finally get it! (Then you can move on to a unicycle! And sharpen to sub-50 Bess.)
Great advice! We sell some plastic guides that we love.
What type of wood cutting board? Acacia like Matsumoto Sakari or Hinoki wood ? My mother says hinoki feels too soft.
Also is 220 grit too harsh for Shun knives?
Hinoki is good! Soft is also a good thing for japanese knives! 220 is a great starting point for Shun's but you'll want to finish much higher!
Do you always need to start sharpening with a coarse stone like a 220 grit or can you start with a 1000 grit then move to 6000 grit for finishing? I only ask because I bought a combination stone and was wondering if I needed to get another. Thanks!
Not at all! If the knife is dull you do need to start on a coarse stone, as starting on 1000 will take too long. If it's in decent shape still, you can start on 1000. Np need to finish a softer western knife on anything finer, but Japanese knives usually benefit from polishing higher than 1000 grit!
Why are you removing the burr with the honing rod after each stone instead of using the 'peanut butter method'? Thanks
Good question! The spreading method works well, but still leaves a substantial burr. The honing rod clears it up fully so we don't get a false positive when we're raising a burr on the next stone!
@@KnifewearKnives why is the peanut butter method even considered a method then if its not ideal? This sharpening stuff drives me bonkers as everybody has a thousand opinions 😂
can you do straight razor sharpening on japanese natural whetstone
Absolutely! I generally use 4,000, 8,000, and 12,000 grit
@@KnifewearKnives awesome
When you are pushing the knife spine side facing away from you, are you only putting pressure on the blade in the forward motion? Same question for when you flip the knife with the spine facing towards you, do you only put pressure when pulling the knife back?
Good question! We apply pressure in both directions, it makes the sharpening go twice as fast!
Haha quite jenius idea:-))
How much pressure are you using with your fingers on the knife? And is it applied in both push and pull directions?
Generally a very gentle pressure, never pushing hard, and definitely in both directions!
Hello, are you using US nickels to measure the angle or will the US nickels be different? thanks!
They're only slightly different, so they'll work!
An i sharpen my everyday Chinese Cleaver this same way too with your Japanese sharpening way ?
Yes, absolutely!
I have a Knifewear 220 Grit Truing Stone - is that an acceptable replacement for a 220 whetstone to use for sharpening?
Unfortunately they're made differently and the trying stone doesn't contain all the abrasive of the regular 220, but in a pinch it would probably work.
I’m currently waiting for my second fujimoto knife.. been using one for about a year now and it’s CRAZY AMAZING…
I would love to learn to sharpen like this. Videos are one thing but having a teacher would be amazing!! Appreciate your skill!!! Have a great day (:
Glad I can help!
I love how many "pro" sharpening videos there are yet they cant even make the scratch pattern go the same direction on both sides
Why would that matter? I understand if you are thinning or sharpening a wide bevel but why would the tiny primary bevel matter. He is going for performance not a mirror edge.
just did my first knife sharpening and actually had fun doing so! Thanks so much for the video, I felt nicely guided through the process. Though just the moment when you mentioned to be careful not to cut the leather strap, that's exactly what happened with the tip of my knife 😂
This is a very informative video - thank you. I really appreciate the simplicity of the presentation.
Happy to hear it, thanks for watching!
I've been sharpening knives for ~3 years now and have basically just been doing my own thing. My knives have always come out sharp... but in hindsight, its probably just becasue it was just trial and error where I just sharpen until it's sharp and the first half of sharpening I was probably not doing anything/hurting the knife! This is so helpful!!!
A burr is like steel peanut butter. The grit of the stone drags metal off the bevel, and it hangs on at the new apex you are forming. Some guys with a SEM (Scanning Electron Microscope) photographed two types of burrs which form, one for softer steels, and one for harder steels. The softer steel is easier to de-burr. If you think of peanut butter clinging to the edge of a butter knife as you spread it, that's what the steel does when you grind a knife on a whetstone: it clings to the apex. If you have a USB microscope, and want to see a big burr, to form a picture of what one looks like, take a knife and grind it on a sanding belt. That will leave a huge burr for you to inspect.
I will practice with my Japanese knife. Should you only use wood for chopping on? Wood chopping board?
Wood is best! End grain preferably but side grain is okay too!
What is a better cutting board for Japanese knives- hinoki wood or acacia ?
Hinoki wood is slightly softer, so I would use that!
Great video. Up to what grid stone are you using the stone fixer?
You can go as high as you'd like depending on what the knife is being used for! If its vegetables, maybe stop around 3000 to leave it a little bit toothier, for meats go higher! Maybe 6000-8000!
A really good instructor on how to properly sharpen a knife correctly.
Thank you!
Thanks for this - I just bought the Nigara AS/S Tsuchime Kiritsuke Gyuto from you guys. I love it but wouldn't think to throw it through my 3 stage electric sharpener. I have a good whetstone set but always got discouraged when I tried to use it. I will try the quarter and thimble trick on some of my beater knives to see if I can get a nice sharp edge. Thanks for all the content and for your great customer service. I will be a return customer for sure!
Awesome, I'm glad we could help! Good luck with your sharpening.
He’s using nickels not quarters!
Amazing video! You are a fantastic teacher. Very detailed
Thank you!
Naoto is awesome, I like all of the presenters though :) Knifewear is one of the coolest companies for us blade nerds.
fantastic instructions. THANKS!
Thanks for watching!
I have a question regarding the soaking and non-soaking stones. I currently purchased a combo whetstone (#1000/#6000) and was wondering if I can soak the whole stone or do I just soak half of the stone (#1000 side) since #6000 is a fine non-soaking stone.
Hey there! I would just soak the 1000 grit side. Some 6000 grits like arashiyama benefit from soaking, but others can crack.
pull toward you sharp push away blunt repeat thie cycle over & over you are wasting ur time edge wont b sharp u are just removig to much metal & frustration sets in this video perfect if you want a blunt knife
This is a common misconception, but not reality. Working in one direction just means you're moving half as much steel as you could be, and makes it harder to keep a consistent angle. Once you're removed your burr, you're got new geometry for your edge! Hope this helps.
any guidance on what coins to use in Australia to achieve 15 or 22.5 degrees? I'm mostly interested in 22.5 degrees as my best knives are German and the rest no-name
mucking with Australian coins and an iPhone leveler app, a 20c spacer and 5 x 20c coins gets around 22-24 degrees - close enough for me
Dear which sharping stone u use and which brand and where i buying it pls reply me ❤
Hey, I used this series of stone:
knifewear.com/collections/knifewear-stones-and-accessories
Good!
Very clear and useful.
Thank you!
Great tutorial. Thanks a lot.
Thank you for watching!
What is the difference between the nagura stone and the bigger flatening stone? Can't they serve the same purpose?
They can! The nagura stone works like an eraser, cleaning grit off of your fine stones. You won't want to flatten finer stones with every use, so the nagura keeps them clear and working well.
You can just use a truing stone, but you wouldn't want to use a nagura in place of a truing stone.
@@KnifewearKnives so the nagura is a much gentler approach more suited for fine stones but not enough for coarse stones
I have a question regarding evenly sharpening sides. I have noticed that I must grind-whetstone quite a bit off the first side to create a burr. When i go to do the second side, it creates a burr in much less strokes than the first side (since it is asymmetrical) do I keep grinding on whetstone second side to make sure both sides are perfectly even? I came up with a counter system- thumb thimbles and measuring tape...I have 3 thimbles to represent each side. Heel-mid-tip...I count 15 strokes on each part of knife and advance the respective thimble one step Just wondering if both sides should be even come the end of the sharpening? ie does this make the knife blade "weak or dull faster"?
Hey, good question! Most people sharpen the same side first every time, which creates an edge biased to one side. This is totally fine! Most people won't notice it and it won't have a serious effect on the knifes performance, although it may cut subtly to one side.
It sounds like your method for balancing it is great! Another option is to start on the right side one time, the left side the next time, and so on, but that can be hard to remember. Doing a set number of strokes per side until you raise a burr is a surefire way to keep it balanced!
Thank you! I will figure out how many strokes I can do to maker this even on cheap knives.
I know they are similar, but are we talking US nickels or Canadian?
Great question! We're based in Canada, so we use Canadian nickles.
No coins required for 15 degrees. Tangent (opposite over adjacent) of 15 degrees is 0.25. So raised the spine 25% the height of the blade. For 20 degrees it would be 36%, not so easy to eyeball.
Can you show how to sharpen chinese clever? Its so big I cant use thumb as guide
We will add it to the list.
