Magnetic blocks to hold a knife at different angles to sharpen with the Tumbler sharpening system. A 15/20 degree block is standard with the Tumbler, but Japanese knives like Miyabi require an 11 degree block.
I've included a bunch of different angles, but if you need something else or a different combination, please leave a comment and I can make something different.
6mm x 3mm magnets fit in the holes on my prints, just superglue them in:
