Indeed, however poorly heat treated steel will quickly lose its keenness/sharpness regardless of edge angle. e.g. bye bye phonebook paper slicing after cutting hard materials (includes hardwoods such as rosewood, snakewood and even as soft as bamboo)
Good example of how changing the edge angle can make a steel look tougher. I for one have taken note of the acute angles you have used in the past to test the steel itself and not "massage the results" by using a more obtused edge angle.
Right on. Many if not most production knives sharpened 18 or higher dps along with fairly stout tip. 12dps is my go-to test edge for small knives and 15dps for users and axes.
A funny clip but it has a lot of meaning behind it. Manny other knife makers often do tests of cutting nails, breaking concrete blocks and the blade remains intact just because they make the angle of the blade very large. And you always test at super small angles to see where the limit of the performance of material with your HT.
I was playing around with an old Ganzo fh11 in D2. Sharpened it to 12 dps and did 25 cuts/chops through an old outdoor extension cord (the generic orange ones) and it still popped arm hairs in that section. I'll never understand the people who think 20dps is reasonable on an EDC. I dont even sharpen axes that obtusely.
this is so good to see. geometry can overcome a lot in lacking microstructure.

Heheh agreed. Satirical - geometry is physmagic, also preconception on D2(or 1095, etc.) need to re-think...

Agreed.
Hahaha great video as always, giving joe x a run for his money. 😂
Heheh could improve, but will take *as it* no-script cut#1
@@BluntCutMetalWorksall jokes aside you're heat treatment and bevels are awesome. Looking forward to what else can be pushed to its limits.
