Positioning tools at the right angle to sharpen them drives me crazy. I can’t stand messing with a block to hold the tool at an angle, but I know that the right angle can really affect the quality of work that I get out of my tools. Luckily, the Sharpening Box makes it easy. Just set the angle you need, clamp in your tool, and hone away with a flat motion.
Since the box provides a flat surface, you don’t need a humongous stone to slide your knife across. Gary Blum demonstrates the technique in this video on his site.
The only problem: The Sharpening Box runs $150.
