Precise angle adjuster for Hapstone R1/R2/M3/V8

Absolute must have for the R2. It is simple, accurate, and easy to use. Also, Hapstone's customer service istop notch. I also have one of their premium diamond stones and one of the cbn start stones, both of which are excellent.

Definitely makes it easier to adjust compared to the stock rod. I am able to get the exact angle I am searching for without having to fiddle with the old rod. Highly recommend this upgrade. On top of that, I think this is more sturdy and should be the stock option.

Great service, quick reply to questions. Great people. Am=ngle adjuster works perfect. Gives added level of venire adjustment to height/angle. Wonderful system. Highly recommened
