Edge retention test: Maxamet at 17dps versus 154cm and 14c28n at 12dps

- They say that geometry cuts, and is actually more important than heat treat or the steel composition of your blade. I test that theory, comparing a Maxamet blade sharpened to 17° per side versus two budget steels sharpened to 12° per side.
Of course there's more to edge retention than just steel composition and edge angle, but hopefully this will be of interest even without specific numbers for the hardness blades involved.
Link to Dr. Larrin Thomas' excellent articles on the qualities of different steels and the effect of edge geometry on performance:

I've been doing the same test for a while and I agree with you. Geometry and head treatment is more important than steel.
I found in some ganzos in 440C and D2 the same edge retention than in a Para 2 is S45VN. or WEs in 20CV
I found better results in Civivis 14c28N than Kizers 154CM. Maybe Geometry.
It would be interested get a knive (same model) made with different steels and play with the angles ad grinds and see what happens with the edge retention
Hmmm, interesting thought. So happens I have Manix 2s in Cruwear, 15v, and s110v, and I have Bugouts in s30v and s90v.
If you used the Ken onion work sharp to sharpen those blades you will see a major pick up and performance from the maxamet if you sharpen on diamond in my experience.
Agree! Any steel with significant vanadium carbide volume will benefit from sharpening on diamonds or CBN. In this case, it was sharpened on a Tormek T-8 with a 600 grit CBN wheel and then honed/stropped on the Ken Onion with leather belts. The first stropping pass was on a belt loaded with 1 micron diamond, and the final pass used a belt loaded with Tormek PA-70 (AlOx) compound. I usually get my best result by finishing up with AlOx or chromium oxide, even with vanadium-heavy steels. I don't think it degrades edge retention as long as the vast majority of the work was done on diamonds/CBN, but perhaps that's a test that should be the subject of another video?

Are super steels really "super" steels when it comes to knives?
There are some extremely high wear resistant steels, like elmax. The down side of such high wear resistance is that they are incredibly tough to sharpen once they’re dull.
