Stainless Steel "Bush Knives"

About 11 years ago I made up two pretty much identical
bowies with 12" blades. I made them with the intention of
abusing them, and kept everything as simple and quick to
make as possible with that in mind.

One blade was A-2, the other ATS-34. Both were heat-
treated by Paul Bos. At the time I sent my knives to
Bob Engnath ,(God rest his soul), and he would send
larger batches made up from many small part-time and hobby
makers to Mr. Bos.

Two fairly identical knives in two steels done by the
same heat-treater. I didn't actually destroy them, but I
did abuse them quite a bit. Both actually stood up pretty
well, but when I got to REALLY chopping and brush-clearing
the ATS blade did keep getting little knicks and chips in
it, and the A-2 did not. Also, the A-2 took a slightly
sharper edge, and was much more aggressive in cutting, as
well as being much easier to re-sharpen.

Since I did't destroy them, I'm not sure what the
comparison would have been. I'm not even sure the cutting
comparison was a fair test, because I might have improved
the performance of either or both by changing the edge
geometry, and I did not do that.

Still, everything else was equal, ie grind, size, shape,
and edge. Since then I have stuck pretty much with ATS for
high-finish or knives up to 10", and A-2 for the occasional
larger piece. I have seem some indication that 440C is
tougher than ATS in a larger blade.

Are you of the opinion that 1095 is a better choice
than 5160 for the larger blade?

5160 is a good choice for any hard use knife, however, you won't get that good edge holding that you would with other carbon steels

The wear resistance of 5160 (or L6 or similar) is quite low, however you don't need wear resistance in a large chopping knife as wood isn't that abrasive. Dulling will set in by deformation and fracture so the main qualities a steel should have is a high hardness and toughness. You get a properly hardned 5160 blade (try a HI khukuri) and it takes a *lot* of wood chopping to dull the blade. Check out the GB axes for a similar steel and how well it performs on chopping woods.
