INFI is just kind of like sr77 that is more corrosion proof imho.. Unless you are Cliff Stamp or another knife torturer that is!! <img src="/ubbthreads/images/graemlins/smile.gif" alt="" />
SR77 can still chop thru concrete blocks. That's tough enough for me. That Marine Tuf Cloth seems to prevent rust well enough for Navy Seals, so the corrosion issue can be dealt with easily enough.
