It's the shutter in your camera that phase with your lights ac current at 50 or 60 hz. When your shutter adjusts to the brightness of the blade, the shutter rate possibly start to sync up with the light source in your room. Change to a regular bulb or fix your exposure to a permanent setting on the camera
The laser etching by country of manufacture was interesting. I like trivia. Great video by the way.
Very well done. IMO one of the most informative videos you have put out.
Fantastic. One of your best vids!
Great video. This has been very helpful in understanding the subtleties of sharpening.
Very informative. I’ve heard of micro-bevels but never owned a knife with one until this week when I bought a cheap Ruike flipper. I looked at the edge with just a strong magnifying glass and didn’t understand what I was seeing until I watched your video. 👍
Wow! Good information and very interesting! Thanks for posting.
Hey, thanks for posting this video, this is awesome.
Keeeeeeeeeeep this up buddy! I love microscopes. You learn so much and its fascinating even if you know what it is
I'm learning so much from you! Thank you so much!
Kind regards from Amsterdam
Awesome video. Extremely helpful.
Nice video, was looging for something like this for a while. Thank you.
Great vid! I definitely enjoyed the micro views.
That is really interesting, nice job!
cool to see the close ups - thanks
Very informative. If anyone is confused about how an edge is formed, this vid would explain it.
Wow very nice polish on that micro bevil
this is beautiful thank you
very cool video. I have a whole new perspective on my edges
I just bought a edge pro and luckily found your channel here, now Im watching all of your videos. Thanks for the help.
Joao Indiani how you like the edge pro
Enjoyable video, that helps me learn what I’m sharpening
cool vid this is going to give a unique point of view for future knife review good job.
Just GREAT!!!
Excellent Excellent Video!
Cool video, very informative =) Thanks for sharing!
Nicely done! :)
Very cool!!
Wow you really kmow your bevels I listen an watch virtuevoice and you channel poped up great job and thanks for taking the time to teach others howcto do things the correct way.thanks again.
awesome!
very cool!
Good stuff !
Nice job 👍
Thanks for doing the video It was useful.
It would be interesting to see the blade close up without magnification first and then with magnification so we can get a sense of the edge we are looking at.
that wacky light show that flashed showed the microbevel pretty good
Very cool
Sweet. Will help!
That's cool...I use a magnifying glass, thanks to you, in my sharpening kit. It makes looking for the burr, chips, rolls so much easier..I get better results
You spent all that time sharpening aus 8 to that degree of sharpness? Wow. I salute you
Now you got me over here with my 10x jeweler's loupe seeing what I can see on some of my edges, LMAO! I just sharpened up and stropped my Manix 2 LW in CTS-BD1 and it's a really nice cutter, the edge is not mirror polished but the bevel looks pretty nice and uniform.
I for one think it was very cool seeing these things, more, more! HAHA!
I've always been the type that liked grabbing my binoculars and magnifying glass and exploring everything. I used to look into my cuts with a loupe too. LOL.
very cool
I like the Taiwan Spydie the best, pretty cool. Very good info, keep it up. Thanks
@TheMotorick It's an Aven Mighty Scope 1.3m :)
Never knew that about the logos, had to look at my delica lol, that is pretty cool
fantastic photos i'm sorry you had problems. dennis
Thnx for the vid man. It would be interesting to see some other grinds, a convex or a 0 scandi grind and such.
@pablofcb21 I plan on doing a close up of the edge before and after the test to compare. :)
nice stuff men! you should add a section using the microscope at the cut tests!
thanks and keep up the good stuff!
Awesome vid bud, the only thing I was wishing for was for you to say what angle you were using for the secondary bevel and the microbevel.
Thanks for share....GBU
after getting the burr in both sides....im doing something wrong...i dont get the really sharp
I've got a question for you. I recently purchased a edge pro system and love it for the most part, but have run into an issue. After I've gotten my bevels and start using finer grits (600 and up), I get little, very obvious, scratches in certain parts. Could this be from my "technique" or perhaps something else? I'm a bit confused as to why this is happening, as I have use other guided systems before (clamp system) and never had this happen. Any insight would be greatly appreciated and if you have done a video on this, please send a link. Thank you.
Yes, the edge finish should not be confused with the beveling terms, but this is mainly a hobby type discussion so the terms go all over the place. If you check the literature the bevels are very clearly defined, but not every author uses the same definitions either.
A micro-bevel is just that, a bevel which can not be seen by eye, it isn't maintained as such it is simply ignored when sharpening the apex bevel. The blunting of an edge would exceed the extent of the micro-bevel which has to be reset if one is desired when the apex bevel is sharpened.
I would personally like to see what you can do to some VG-10 bro... then show us up under the 'scope. I love VG-10, not the best available these days but it certainly has a place in my heart after having performed for me for so many years.
Also... I'd love to see some edges after you do your cut tests on the rope, to see what all kinds of micro damage is occurring... I vote for that for sure. Basically anything to give us all some more data and knowledge on the subject is good in my book.
what magnification are you using
After using stones to create a toothy edge, how does stropping effect it? Does it refine a toothy edge or round off the teeth which would reduce the "bite" I'd think? The strops I use are cow hide leather wth DMT diamond paste (6 and 1 micron). I also have some horse hide leather strops. It is much harder than the cow. Have you ever done a review of different strop material? Leather types, balsa wood, cardboard, etc. Murray Carter just uses newspaper layed across a stone. Your thoughts?
thanks B
Great video man and I kinda think the flashing of the light really brings out the mirco bevel. Just a thought
The terms used in discussing knives are not well adopted and everyone tends to use their own preferences. Technically a micro-bevel is another bevel however when switching grits even with clamp/jig systems the stone heights can make small changes in angle so technically you could end up with 3-7 bevels but generally no one would regard them as such as none are visible or intentional.
did you upgrade your microscope. If so to what? Great pictures!
12 years late to the party, but thanks for the vid.
I think the lens is trying to auto adjust to the rapidly changing light due to the reflections as you rock the blade.
thee blinking on and off is likely an electronic effect in the video cam. Look at where on the blade you are lighting when this happens. I've seen that when the light reflects in 2 directions and confuses the camera.
How do you create a micro bevel
Cool
Your close-ups were pretty good considering. I have to ask, what kind of microscope were you using? I want one. :D
Maybe try this in a light box/tent, the softer light might work out better or maybe not. Keep em' coming.
i'd imagine a toothy (650) micro bevel would cut better initially but a let's say 6000 grit micro bevel would last a bit longer? i know a micro is much easier to touch up / hone, but does a solid beveled edge, with no micro, last longer?
What do you think about Barkriver knifes?
would a 100x magnification be enough to show what i am doing to the edge when sharpening!? or is it not strong enough
Once you begin sharpening a knife after purchase/use, how long can/will it take to remove the micro edge?
Yeah the term micro in a lay sense just means small, like the micro-machine toys. However the actual academic/metallurgical use means micron scale. The problem in using a vague definition is that the discussion gets problematic because a micro-bevel which is on the nature of a micron is very different than one which is on the scale of 100 microns (which you can barely see) in how they effect performance/sharpening etc. .
Ironically, the name of my channel hints at nano-bevels.
Hmm, informative! !
600? I always assumed the spyderco white ceramic stones were more like 2 or 3000 grit?
@chewy667 Emersons and the sharpmaker don't mix well. I'm guessing your edge veers way off to one direction when cutting through material
What was the magnification level?
what did you sharpen that cold steel on?
cool
May I please send you my knives to have a edge like this?? You have a website?
@jackchn23 That's the plan! Should be cool. :)
Try playing with colored or polarized filters
I don't feel as though micro bevels do give strength... they just make sharpening easy and save metal. My factory edges that have no micro bevels always hold up much longer than after I micro bevel with a sharpmaker. I think I need an edge pro.
+ford fairlane well this first comment was over a year ago, I had since bought the edgepro. I generally do them free hand, or if i'm feeling goofy i'll use the sharpmaker. I generally do not micro bevel knives though.
what magnification are you using?
What are you using to view this? Do you know of anything that would connect to a phone to allow you to view? Praying you start making sharpening videos again. RTR?
Duuuude, greeaat vid!! Love the info. Nice cam work and polishing. Here's an app that android users can use to see very up close and magnified,,,, it's called "Magnify" in the android mkt, it's free also. Peace out
How do you remove a micro bevel?
id like to see a before and after strop vid with the microscope
With what tool would the precision sharpener use to reset the micro-bevel?
Yeah, I think calling a toothy edge a micro bevel is incorrect. Basically, isn't it just a toothy edge?

Also, interesting video.
This looks like a job for 1080p!
so what is better a polished or toothy edge?
Butchers want a toothy edge, that saws through the meat. That's why they use relatively coarse stones and a coarse butcher steel to create new teeth into the edge.
@jdavis882 please! that sure will be awesome!! :)
Micro-bevels in industry are usually what results after a pass on the buffer, the angle and width of the bevel will depend on the force used, the number of passes and the nature of the wheel (softer wheels produce larger bevels). As the micro-bevel is just that, micro, the performance is relatively insensitive to angle compared to the primary or apex bevel. You are talking about the edge to an extent on the order of 1/10 of 1 thousand of an inch.
Is "toothy" just tiny, tiny, tiny "chips"?
Ken Smith imagine a serrated knife. Now think of those teeth getting smaller and smaller everything you go up in store grit. So yes in a way. Toothy is like bigger teeth at the apex

Hmmm...I have some beefs with micro bevels. Start off with, the manufacturers do not specify that they grind such micro bevels, that I know of. How is an owner supposed to sharpen a knife with a bevel he cannot see, and wasn't informed about? It's so small, who is skilled enough to maintain a micro bevel? How would you know if you were accurately maintaining such a bevel without an expensive microscope? Manufacturers are grinding edges that defy maintenance, and fool their customers.
