154CM = better edge retention - less durable - more common SR-77 = less edge retention - more durable - proprietary to SY SR-101= Even more edge retention - even more durable - Proprietary to SR INFI = Most retention and durability of all of these and proprietary to Busse blades...
Correct? I'm just making sure i have all of this down. <img src="/ubbthreads/images/graemlins/smile.gif" alt="" />
Basically correct, except that SR-101 is not as tough (if that's what you mean by durable) as SR-77. Also, 154CM is classified as a stainless steel (more accurately, corrosion resistant), which tend to be more brittle than non-stainless steels, although 154CM is one of the best; INFI is not considered stainless, but has fairly good corrosion resistance. SR-77 and SR-101 are both carbon steels and will rust if not cared for, although reports are that SR-77 does not pit as badly as SR-101.
