The Bevel Grinding Jig from TR Maker is their smaller jig design. It has 1 point of adjustment for the angle at which it comes into contact with the belt, which makes it faster and easier to adjust.
I personally use this jig and prefer it over the 2-point jig.
If you couple it with the file guide, you can bolt the file guide to the jig itself. Then you don’t have to take the knife out of the jig, you can just quickly switch it from side to side.
Made out of high-grade 6061 aircraft aluminum and coated with an anodized satin finish to protect from corrosion.
