I think S7 is a better value than INFI. Everyone seems to think INFI is better but is it twice as good? I would take a 10% drop in performance for a 50% drop in price. Or better yet a 1% drop inperformance and a 50% drop incorrosion resistance. Rust is not a big issue for a coated blade. A steel i have heard of that specs out alot like INFI is hitachi blue steel. It would make an interesting knife.
