Their knife clamp has ABS angle-guides that fold against the clamp’s body - a set-screw in the back locks them together - they’re marked for 20-25-30-35 degrees. You get 3 color-coded and marked stones - coarse diamond, fine Arkansas, and a ceramic for serrated knives. The guide- rods feature threaded brass lock-collars, and everything comes in a zippered nylon case.
