I have three knives. I bought one directly from Busse, another from their web site and one from a BF member. Their INFI steel is remarkable. I've used them quite a bit and only had to put 1000 grit sandpaper and a leather strop on the steel to keep it sharp. IMO they sell a very high end product. I won't be able to afford anymore, but I'm sure the three I have will last me a lifetime.
