Virtual BBQ WIP. GNiCr40Al4 frame lock folder.

Dane, thanks for asking. You got me motivated to do some cutting.

I test cut some heavy corrugated cardboard and did some whittling on a broken hickory hammer handle. I wanted to test it against something, the only knife I had roughly comparable on hand was a CRKT Ripple, the Ken Onion model. Results:

I cut out some test pieces of cardboard, so the cut would be about 3" across the corrugation.

I sharpened both knives to hair-popping with a leather belt and green compound on my 1x42 Viel S5. The CRKT is Acuto stainless.

After 20 cuts each, both knives were cutting with drag and would no longer shave hair. I resharpened.

After 10 cuts each, the Acuto blade would not shave (A) and the GniCr40Al4 (G) blade still would, but not as thirsty.

I repeated the 10 cut cardboard test after re-sharpening. Results were the same- the G blade retained more sharpness in this abrasive medium.

I resharpened.

I whittled curls off of a 1" plane on the end of the hickory handle, down through the grain at about 20 degrees, trying to use the whole edge of each knife as much as possible. The A blade being a combo edge has little bit shorter of a plain section, so results might have to be adjusted slightly.

After 30 cuts, both blades were still good and shaving sharp. I proceeded further without sharpening, testing on my arm after each cut series.
20 more cuts, still no appreciable dulling.
20 more cuts, the G blade had dulled very slightly but the A was still good.
20 more cuts, G a bit more dull, A still good.
20 more cuts, G slightly duller, A slightly duller. Both still shaving hair.
20 more cuts, both still about the same.
20 more cuts, both a little more dull. Still shaving.
20 more cuts, G blade developing spots of non-shaving, A blade still shaving OKish.
20 more cuts, A still mostly shaves, G mostly won't.

At this point I cut cardboard 10 times with each to finish them off- I was tired of cutting. Both dulled past shaving for sure afterwards.

A pretty basic test, my limited conclusions:

G cuts better in cardboard, an abrasive material. A cuts better and stays smoother in hardwood. Both are pretty good, G seeming to hold up pretty darn well.

My arms are bald now. A pic of the knives and materials:

lol I was gonna say why did you stop? Run out of hair? Then I scrolled down and saw the arm, then I finished reading. :p
 
Thanks for the testing! I was really interested in how this steel would perform. To be perfectly honest I didn't even think it would do as well as it did, but with that composition I really had no basis for comparison.
 
nice work and very useful test information. i am think this alloy can be really good at manufacturing small hunting knife. or butcher knife. knifes required to be clean very carefully after gutting animals. this thing can be simplely heated to over 500F to kill all the germs. temperature below 800f in less than 1 hour cause no change on this alloy. no surface oxidation to affact sharpness as well.

few days ago i was asked if this alloy can be carried by pass the metal detector at air port. i did not know why he asked that. but the answer is no. it can be detected by most type of metal detector, and can be detected 100% by the metal detector they are using at air port. so don't try anything stupit if any of you are planing it.
