So, this is my second knife, ever. The handle is black walnut with red G10 spacer. Blade is 01. I heat treated and tempered the blade myself. I had it tested, afterwards, three times for HRC and the readings all fell between 48 and 52. I bevelled by hand file, with a guide. Made sure to draw file, to level/straighten the blade as much as possible. Also sanded the lower portion of the blade up to 2,000 grit, starting at 150. Used a home made metal sanding block. The larger surface of the blade was run on a belt sander at 400 grit. In retrospect I'm not sure that was a good choice on my part. Blade has a 25 degree cutting angle on it and is a lenght of 4.75 inches. Let me know what you all think. Thanks!
