I have a Boker stag trapper that I got about 1986. The 440C is pretty good, the only knife I have ever done a direct comparison test with was a Puma stockman that I got in 1984, the Puma held its edge better. But for a 440C blade I would rate the Boker about typical for that steel. That was a while ago, hopefully Boker has the same or better heat treat now. The Boker slipjoints that I have purchased over the years have all been very well made, great fit and finish.
