The Flat Bottom ‘V’® (FBV®), is an evolution of the traditional method of sharpening skates. The FBV® has recently been introduced by Black Stone Sports® to coincide with their innovative ‘Spinner’ patent pending dressing system.
The Flat Bottom ‘V’® (FBV®), available only with the Blackstone® ‘Spinner System’, offers the skater the ability to have both speed and agility. A blade sharpened with the FBV® has the flatness of a shallow hollow and the edges of a deep hollow (the depth of a 2 inch radius and the bite edges of a ½ inch radius).
The edges of the FBV® are keener, so the same edge may feel sharper than the one you are used to. This allows you to skate on less of an edge and maintain the same bite. If you have tried the 90/75 and feel that you do not have enough edge, you should then try the 100/75. From our initial testing, we have determined that the 90/75 can be related to the edge of a 5/8 circular hollow and the 100/75 can be related to the edge of a 1/2 - 3/8 circular hollow.
The FBV® provides the best of both worlds when it comes to speed and agility. With the flatness of close to a 2” radius, you will notice more speed and less drag. If you are used to slowing down when you stop pushing, you will notice your glide is a lot longer. With the FBV®, you will notice a decrease in the number of strides necessary to get from end to end. Along with the increased glide and speed, you will notice that you still have a solid, keen edge to allow you to be as agile as you were before, if not more so. The result of this combination is more speed, solid edges to bite during turns and stronger legs right up until the final buzzer. With the FBV®, you are able to increase your effectiveness on the ice with less effort.
