What does a dull knife look like under a microscope? We compare a dull knife to a very sharp knife under a microscope. I also take you through how I sharpened this knife.

I invested a great deal of time and effort trying to replicate what 55 does. It was a long process (over a year) for the blade to not be worse after my sharpening. I wanted the skill on the stone not the edge from the Lansky or the can. Then one day I just understood and I was able to whittle a hair. Now all edges are wicked. Thank you 55.

Yeah. The time I got to sharpening was about the "knife shop" that offers sharpening. Gave them the knife, 2 days later got it back with only one side of the blade sharpened - the opposite side was straight as a line. Well, that was it. Bought first stone, watch videos (I consider myself lucky to stumble over you) and started sharpening. Great videos, keep up the exellent work. Also, dull knives cut different. Sharp knife is faster to heal if you cut yourself.

Pete is going to be upset that you didn't show an edge dulled on hundreds of feet worth of twisted sisal rope. 😜 Also, the scratch pattern left by the 5K Kuromaku is very impressive. I wonder how similar a 5K diamond plate would be? Grit numbers across different abrasives are a bit strange, it seems. I always go finer with diamond to get what I believe to be similar results.

Edge may wear by abrasion, rolling, chipping or corrosion. This is important because if you evaluate edge durability with a test that causes abrasion it will not be very useful to predict durability on tasks that wear down the edge by other methods.

I have been the go to guy among my friends and family for sharpening almost everything since the mid 80's. I find it very relaxing and satisfying. But I have learned so much in the last few weeks since subscribing. SEEING IS BELIEVING when it comes to the apex of a blade. ......So here is a tidbit I thought you may look into: I recently picked up the 600 grit 8" Tsuboman stone you suggested and is amazing compared to my old DMT collection. I do have a DMT extra fine and a standard steel in the knife block at home. So, after seeing the burr being the reason I had apparently sharpened blades go dull so quickly, I was out in the woods and decided on an experiment. I tried removing the Burr using the magnesium flat of my army style flint fire starter because I have no traveling strop, I was really pleased. So next while at home I tried the almost polished edge of the aluminum base on the new 600. It also seems to remove the burr substantially. I don't have any way to magnify as a you do ,but it is definitely way better than cutting with the foil burr and having a premature dull blade. The edge retention of everything is way better!!!! It would be really interesting to hear your thoughts or even see what's happening

I still remember from back when it was always DoN't CuT CArdBoarD iT'LL WreCk YOur eDgE. I've live streamed 4 hours of cutting dirty cardboard with D2 and it still kept a useable edge. 8cr held up pretty well too. 440 from 1980 did wear at about 2 1/2 hours. And diamond paste on a strop is a rapturous delight.

Yes indeed , a coarse steel will hollow a blade much faster than a fine one, they both do it, but the fine one might take thirty years to do it.

Got skin, paste and 240 grit diamond plate, had 1000 and 3000. Profiled the top 90° side of a snap blade on 240 in seconds(one sided edge), got a nice finish on a 1000, worked the edge from two sides on 3000, done 10 alternating passes on the strop. I got myself a razor in freaking no time. Previously the two plates gave laughable result in comparison xD Big thanks for teaching me, big thanks to the algorithm gods!

A really cool video idea would be a comparison of different abrasive media, like sharpening on all diamond, traditional stones with diamond stropping, and if you can get your hands on some, traditional stones with traditional stropping. Since I've gone to all diamond, I noticed my edges are much more aggressive cutting and seem much sharper, especially super steels with tungsten and vanadium carbides.

i think an interesting pair of things to test and look at the edge after are cutting a soft metal like copper (i cant tell you how many times ive been asked to cut electrical wire with my knife) and chopping in to wood across the grain- wheather it be batoning the knife or chopping with a large knife. i just wonder if they would create dullness in the same way or if the damage would look more like rolling or micro chipping.
