Great review, Bodog, thanks for all the hard work!
Youre welcome, it was fun!
Great review, Bodog, thanks for all the hard work!
After saw your zt0180 edge after cutting a nail, I was curious about my SQ 52100 strength & toughness.
Spec:
52100 super quenched; 61rc; sharpened 20dps with 0.025"(1mm) behind edge thickness.
Cut a 16d size nail into 6 pieces. 1 cinder block cut. And cut 1 small rock.

Thoughts/assessment?
There are a couple of things a little different. I don't know exactly how much difference they would make. Your blade is sharpened at 40 degrees inclusive, the ZT was sharpened at 32 degrees. The spine and primary bevel look a little thicker on yours. I don't know what kind of nail I tried cutting through but it took harder shots without splitting until the hammer broke. I also placed a small piece of 2x4 between the hammer and the spine to prevent the dings from the hammer on the spine. I don't know of cutting a piece of a cinder block is any easier or harder than trying to cut at a full block.
Having said that, your edge looks like it took less damage than the ZT. ZT also cannot really hit a superb heat treat regimen doing them in large numbers without really jacking the costs up.
I've always been interested in your blades. When you had the test blade giveaway my name was on the list. I was really hoping to test one of them and post the results. It disappoints me a little that the guys who won haven't posted anything about them. I really think it's quite possible you're doing something others aren't and that it might very well be making a better blade. Interesting results and I'd like to see others resting their blades for toughness and strength, especially if those makers are claiming their knives are built for rough use. Bravo on your work.
Yeah man, I'd love to test one of your blades...
If you are willing to put a handle on it -> substantially increase the possibility...
Look at D2 vs 3v(or Vanadis4) at 60rc & 62rc

I plan to make a 62rc D2 0.130" thick, 16dps w/ 0.025" edge thick and put it through similar test above. Crazy

Based on your picture, at 480p, the edge damage to yours looks in line with the ZT, although bodog put his knife through a lot more rigor, at least I gather that from his decriptions above of hand fatigue etc from the amount of chopping and cutting he performed, while your test was done in a ~6 minute video -
Here is a screen cap of your damage closeup since your attachment is not displaying for me -
Your process looks to have provided a good hardness as well - thanks for the video.

Edge bevel does looks bad, but dark spots were mostly granite smeared. Here is the edge shown at the end of the video
edited to add: This 6 minutes video was shot, right after I did a 25+ minutes video. Actually you can hear my slightly winded breathing. That 25+m vid contains too many brain dead oopsies to post.
