Universal Angled Clamps for Hapstone R2

They fit great, and I like them better than the original clamps. I bought a 3mm hex driver to make it easier to clamp a knife in place.

They are not the same angle when I flip them over, off by .8 degrees . Also flex a lot. Would expect better for the $$$

The clamps work as expected. The reason I gave it 3 stars is because on one of the clamps, the screw that pinches the clamp shut was completely stuck. I was able to eventually get the screw off but I have destroyed the finish on the clamp around the screw holes. I have found another screw and nut to replace it and now it clamps down like it should.

can't hold a proper angle with lots of flex and the way it's mounted is slopy at best

As always product's from Gritomatic are top notch so when purchasing accessories of any kind to include these Hapstone Angled clamps, they are the first place I look and once again I'm completely blown away. Amazing improvement couldn't be happier. If you've been on the fence take the plung it's well worth it!

Worked Perfectly!! Most of the clamps for the Tsprof are sold out at the time of purchase, this was a great alternative. With Hapstone angle clamps and the gear connect adapters I can now clamp any type knife to my kadet, finding the angle is no longer a pain in the butt. Finally!! I’m enjoy using my Kadet!!
