Hapstone R2 Black Knife Sharpener

This is a very high-end sharpener, I like having the four clamps, makes it nice for all kinds of knives, it should last a very long time, I really like the bearings on the slide, I've worn out a couple of others that don't have bearings, the operation is very smooth and well made.

Love the product, but for the love of everything that's holy, please include some decent instructions or a video explaining assembly. I ordered some extras and the original instructions didn't apply to me.

Solidly weighted. Easy to flip the knife being worked on to switch sides without having to remount (like my older model). Holds knives of different sizes quite securely. I advise picking up the available pads to avoid marring your work.
