The patented spinner system changes the way skates have been sharpened for hundreds of years.  The spinner system uses a small 1” disc precision machined with an ROH (Radius of Hollow) or an FBV® (Flat Bottom V®) shape. These custom discs are diamond coated to dress the grinding stone with the specific shape.


Each disc has only one shape, simply grab the disc with the desired ROH or FBV and install it onto the spinner system (no tools required)

The spinner system provides the advantage of being able to sharpen Radius of Hollow and Flat Bottom V.


The spinner discs are precision machined with exact measurements.  The ROH shapes are true and the FBV shapes are unique to any other shape (see FBV to learn more)

  • The Spinner System sharpens the entire face of the grinding wheel at once (unlike the single point diamond which can only contact one point on the wheel at a time), resulting in a longer life for the grinding wheel
  • The spinner system extends the life of the grinding wheel which equals more sharpening per wheel
  • More skates sharpened and less consumables required equals savings and more money in your pocket
