Due to INFI's superior toughness do the Hogs think that a thinner piece of INFI is equal in strength to a thicker piece of standard steel?

My example would be is a 3/16" thick piece of INFI equal to a 1/4" thick piece of 1095 in terms of toughness?

Am I making sense? My apologies if this seems like rambling.

Based on Noss' (extreme) testing with the skinny ASH, I'd say yes. It took more than I expected a thin piece of steel could take.

Infi is very tough stuff!
 
I would take a .1875 piece of INFI and day over 1095 any thickness. 1095 can be a good steel (can be) but I have seen way to much of it left soft. If my life is in the balance, there is NO question as to what I would carry. Leave the customs at home and give me INFI-period....
 
I think that the ultimate and yield strengths of INFI and other cutlery steels are somewhat in the same range. Toughness refers to a metal's ability to absorb energy before it fractures or breaks. Remember, the geometry of the knife will have a drastic effect on the stiffness of a knife in bending. So, a 1/4"-thick 1095 saber ground knife would probably resist bending more than a 1-4"-thick flat ground knife made of INFI. There are a whole bunch of factors that go into making a knife "strong"...
 
Well, having seen INFI blades (and SR101 for that matter) put in a vice and bent 135 or so degrees, I seriously doubt that 1095 of any stripe will compete with it for strength. Most low-end steels, even with the best of heat treats won't really compare well.

When you get up into the better steels, like 52100, 5160, S30V (I think that's what Fehrman uses), you can come real close.

What it comes down to is the complete package. Some steel may hold an edge better than INFI, some (like S7 and S5) may be tougher, but not hold much of an edge, etc. What INFI gives is an excellent accounting in all areas
