Ok, first to answer the original question, INFI holds an edge far better than most steels and it also sharpens about as easily as 1095. What INFI does is it resharpen itself, it will begin to dull and then it will sharpen again while you use it and this strange behavior causes it to last much longer than most steels in edge holding. The only other metals which I have experienced exhibiting this behavior to a lesser extent are Stellite 6K and Missions beta Ti. However, both dull much faster than INFI, but for their hardness have unbelievable edge holding.
Anyway, I purchased my first INFI knives back in 1998 and received them piecemeal in late 98 and early 99. I have used a few of them beyond what they were meant to do. I used one for work strictly and that is the one I do not show in pics. Then I have used another one for this whole time to chop wood, cut boxes, cut rope, and throw. That knife has been thrown over 10,000 times and stuck into wood 90% of the time, and that same knife has been used to chop and reduce 4-5 chords of wood for winter use. I have used other blades during this whole time and none have survived. The most impressive part, besides the fact that it never failed, is that I would not need to sharpen it but once a season after all that hard use. this knife is now in the hands of Pbubsy and he can tell you what it looks like. Also I once posted a video of throwing this knife and a few others and in this video this knife's edge hit the other knife's tang, with amazingly no damage.
