This is an add-on for the CNC Kitchen's knife sharpening tool. I didn't really like the way magnets are holding the knife (especially if it's a bigger one) in the original design, but I also didn't want to redo the whole base. This allows you to clamp the knife a bit more securely, mount it to the sharpening tool and rotate it easily without unscrewing the knife from the clamp

Hardware required:

2x M4 socket screw + nut for the clamp
1x M5 hex head screw + wing nut for the mounting element
