C2 - SeaRay is correct. My 2 hunting knives test either 62 or 63. A buck knife tests around 57. My primary hunting knife has gutted 8 deer, split 3 sternums, skinned 8 deer and then quartered the 8 w/o needing to resharpen. These custom blades are made in Okla for $175.00 and will fit your hand like a glove. Resharpening takes less than 5 minutes on a set of paper wheels. I sharpened several peoples knives at the Winter Camp on my wheels.
