Avoid most of the "440 c" blanks on most of the knife supply websites. While they are a decent value, most are bent, unevenly ground, or have a spotty heat treat. Also many have odd shaped bolsters that will drive you nuts trying to fit handles to. Also the "440 c" blanks almost always are barely sharp, with an uneven edge bevel that can take two or more hours to even out by hand.
Jeff Mutz at Trugrit has the only 440 c blades that come as advertised. They are also very reasonable for cutting, grinding, and heat treating your design. Jantz has some really good 1095 blades that wont cost you hours of fixing like most "440c blanks."
