Over time I found that the abrasiveness of these triangles was greatly reduced as the cube drill was rubbed off the primer. I took great care not to apply pressure when sharpening, understanding that the bond of cubic boron nitride to the triangle is brittle at best, but even with extreme care and very careful use, the triangle will not…

Pros
  • EASY TO CLEAN - Simply scrub with a sponge and scouring powder. Allow the product to air dry.
Cons
  • Obsolete model
