I know Paul Bos is a master heat treater and a Paul Bos blade is generally a good one,but why?What is it that Paul Bos does thats so good?Also I see a whole lot of blades both custom and production that are PBos heat treated.Does he have a very large machine/furnace that treats blades,and how about cryogenics?Is that part of his process as well?Any info would be very interesting,Thanks!
