I've read and watched most everything Clay Allison has put out. It tried this edge. https://www.youtube.com/watch?v=e4w0LqdMcGM

Border line between coarse stones/strop or two and the above edge. His micro bevel edge is a little easier to do.


I gave the Clay Allison method a try and will see how the edge holds up. 15 degrees (each side) for the profile through 1000 grit diamond followed by 4 passes at 200 grit diamond at 20 degrees each side. Definitely a toothy edge.

mdblanton, how do you like that edge?

Picking up knives in Vandalis 4E and 20V today. See how those test!

djpaintles, going to try some Venev diamond stones next week. 150, 240, 400, 800. Will be interesting to see how they cut compared to the metallic bonded CBN stones.

It cuts well. It will slice paper and did a nice job cutting some running vines in the yard. I’m going to use it a bit more and then probably try touching up the micro bevel with 600 grit and see how I like that. Current stones I have for my Wicked Edge are 200/600 and 800/1000.

I'm already looking forward to your comparisons. In my less detailed comparisons than you do it seemed to me that I got less extraneous scratches with the diamond stones and they were a little easier to flatten (no noxious chemicals needed). But I still need to do more knives with the CBN stones for a more accurate comparison. Both are a step above many other stones.

Gritomatic had a really good deal for a while on double sided Venev stones. It was 3 double sided stones for $80 or so. They fit just fine in the TSPROF if not in a regular edge pro. I also had bought a couple in regular edge pro blanks and they worked the same. The 2 sided ones just made for 1/2 as much angle setting going through the progression. :-)

You might check Venev Diamond stones Here:

Thanks again for your tests etc. They've cost me a lot of money on new stones I just "had" to buy LOL but I'm really glad you convinced me to look into them...............


Remember, this is all supposed to be for fun...................

Benchmade 20V. 34 degrees, 300/700/1500CBN, 1 micron strop

14 minutes to sharpen, knife start/stop on the counter.

38 cuts/684"

I haven't sharpened this knife before. It definitely "felt" softer then what I remember from other knives in 20V. Stones cut very fast. The Benchmade specs I found on this knife state HRC 59-61. Maybe it's at the lower end of that HRC?

Spyderco PM2 M4. 34 degrees, Venev Diamond 240/400/800/1200, 1/.10 micron strop

19 minutes to sharpen

88 cuts/1584"

Used 2/3 stones from this Venev Beta Centauri set.

https://www.gritomatic.com/pro...riant=32302488092781

Since following previous angle, no need to go lower then the 240 grit. These stones load fast. Spent time cleaning them with a Nagura stone as using. Edge somewhat polished, some minor scratches left behind. I didn't chase a perfect mirror polish. While this polished edge cut more then the previous sharpening, I prefer a polished/toothy edge.

M4 is a great steel! Good edge retention, polishes very well.



PM2 I've slowly turned into a PM3!

Off grid, thanks again for recommending the micro bevel sharpening method. I’ve been using the blade at work and have been very pleased with it. Cutting things like nylon strapping material has been very easy with no slip as I began the cuts. No slips during the cutting motion = a safer cut in my opinion. I’ve often had slips from more polished edges even though they were very sharp by the hair-shaving standard.
