I often see a nicely made knife as to design , fit and finish only to find it is made from lower grade440 steel or even 420 steel. It leaves me wondering it's a nice knife why didn't they spend the extra $ for at least 440c steel. My question to you knife makers is how much additional material cost is there betweentwo blank pieces of steel say 10"x2"x3/8" one 440a vs 440c. I would think for a company buying in volume it would be a matter of a few dollars if not cents.
