Cutting tests w/4 knife steels

Hey, Possum, long time no hear.

Nope, that's not me. It's something I found
on the Internet. I figured if I didn't say I was
writing tongue in cheek, I'd get lots of posts
telling me I was nuts...well, more posts saying
I was nuts than I normally get, that is!

I do need to get back to Shootersville and see
if I can practice my mind control on Tap...to get
him to buy more knives than he normally would. :D

If I post a photo, I'll do it over there, but only
if you do the same. In the meantime, I'm learning
too much here.
 
Hi Phil, This is great information. I find it particularly valuable since you have honed at what I consider a reasonable angle for a hunting knife. On the other hand some of the difference between these alloys is supposed to show up at lower honing angles. Is there any chance you could repeat your test after honing at 8 to 10 degrees per side?
 
The advantage of AEBL class steels is mainly for high push cutting sharpness, edges which can sustain smooth shaving ability. Edges which only need hair scraping ability and less, especially with coarse edges will have higher performance with more carbide. I am actually surprised that 12C27 did as well as they did on the slicing tests as it has essentially no primary carbide compared to the huge volume in the other steels, ~25% . For that kind of work, slicing rope, until the edge has flat spots and is very dull, 440A would be superior to 12C27.

Hi Phill,

I am looking forward to see more tests on some current supersteels

CPM 10V
ZDP 189
CPM S90V

How do you measure initial sharpness?

Thanks, Vassili.
