Simple to use because of correct angle already built-in. Very effective at restoring a edge to dulled blades shot while practicing.
Thing is excellent just a couple swipes and it was sharper than new. Just don’t shoot at the same spot when broadhead tuning. Let me tell you great broadhead thanks.
Really like the oil. Used it with sharpening stone I also purchased. They work well together. And the end product was favorable. I recommend this product
