Even they are close to performance regarding strength and toughness and have pretty similar hardness in bussekin blades, these two steels are so different! I'm watching the SR77 on my SOD blade where the coating jumped out near the tip and watching the INFI in the same area of my ASH. SR77 is a gray steel, it looks very similar to vidia, while INFI has a color somewhere between aluminium and silver. When they rust, their patina is also very different.

For now, what I can say is that for normal (soft material) cutting INFI holds an edge better (competing with supersteels and defeating most of them in this area) while SR77 is not comparable with a supersteel from this point of view. For corrosion resistance INFI is also better than SR77.

As regards toughness, I have only chopped some cables with the SOD and did no other hard stuff yet. This weekend I'm going to do something harder with it and I'll tell you then how I feel it compared to the Busse Skinny ASH1 (the skinny ASH1 is approx.425 grams weight and the SOD is approx. 444 grams so they are close). As regards destruction testing, I'm still waiting to see Noss testing the Skinny ASH1 as he promissed, on www.knifetests.com. The SOD would be, I think, the same as the Scrapper 6 in a destruction test, but from Busse Combat he only tested a Battle Mistress until now (which is to big to be compared with the SOD).
