Speed and Agility
Have the advantage of SPEED and AGILITY with the FBV®. Using the historic information of the radius of hollow, we have created a shape for your blade that will increase your performance. The FBV keeps the flat portion close to the ice to generate glide on all of the sizes.
By MOVING WIDTH
By increasing and decreasing the WIDTH of the Flat, we are able to manipulate the bite to make it more or less aggressive. This also affects the sensation called ‘purchase’ when stopping.
Try it for Yourself
By manipulating the WIDTH and DEPTH of the Flat Bottom, you can have BOTH – SPEED and AGILITY

With the variety of shapes available, there is a perfect shape for you and your technique.

Try it, I dare you!
By Moving the Depth
The depth of the Flat is available at three different levels. 50 – 75 – 100. The deepest depth, 100, represents 1 thousandths of an inch. Such a small increment is more shallow than any radius of hollow (ROH) available. 75 represents ¾ of a Thou, 50 represents ½ of a Thou

BLACKSTONE® SPINNER SYSTEM
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 or an FBV shape.  These custom discs are diamond coated to dress the grinding stone with the specific shape.

ADVANTAGES
  • Easy to use
    • 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)
  • Ability to provide ROH and FBV shapes
    • The spinner system provides the advantage of being able to sharpen ROH and FBV
  • Accurate
    • 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)
  • Consistent
    • Be confident that the same shape is being provided to the customer time after time
  • Economical
    • 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
AVAILABLE OPTIONS
The Spinner System is available in two versions.
  • SINGLE SPINNER:  The single spinner system holds one interchangeable spinner at a time.  It can hold any ROH or FBV spinner.
  • REVOLVER SPINNER:  The revolver spinner system has the capability of holding 4 different interchangeable spinners at a time.  They can be all ROH, all FBV, or a combination.
** Changing spinners in either version is easy and there are no tools required.  Simply unscrew the drag cap and replace, ready to dress the stone with the desired shape immediately.**
