EXPERT BLADE SHARPENING
The Ice Chalet offers professional skate blade sharpening! You can leave your skates at the counter and come back in a day or two to pick them up. Call us at 865-588-1858 for details.
This is a sport of edges -- so consistency of
the hollow, radius, and sharpness is critical. Monthly sharpening helps you get the
maximum life out of your blades, and
lessons will be more productive!
It depends on the blade, the skill level, the skater, etc.
Done frequently enough, a blade should last 5 to 8 years for the average recreational skater. Generally, the frequency should be every 20-30 hours of skating.
Examples for the average, recreational skater:
1 session/week X 3 hours --
every 10 weeks
2 sessions/week X 2 hours --
every 7.5 weeks
3 sessions/week X 2.5 hours --
every 4 weeks
FACTORS: Hardness of the steel used in the blade, and how much and how aggressively you skate.
- When you no longer feel secure.
- Bottom of the blade appears dull -- a sharp edge, in strong light, gives no reflection. After sharpening, the bottom of the blade will have a uniform sheen. With more use, the bottom of the blade near the edge will begin to appear dull.
- Blades feel “grippy,” i.e., sharp blades feel secure if they are kept sharp. Of course, when changes are made -- correcting errors, changing the hollow, sharpening a very dull blade, etc., blades will feel very different and perhaps insecure.
RADIUS OF BLADE (ROB):
Curvature of the blade as seen from the
side, front to back. This creates the ROCKER look & feel of the blade. The curve increases toward the front. The smaller the radius, the easier it is to turn.
The rear two-thirds of the blade has a 7-foot
to 8-foot curve, depending upon the make
and style of the blade. This flatter
curvature offers the skater more speed
and stability. The front one-third
(approximately) may have a 9” curve,
or two levels of curvature with a partial
radius of 1 foot and another section
with a 2-foot radius, sometimes referred to as the “spin spot.”
RADIUS OF HOLLOW (ROH):
Curve carved into the bottom of the blade;
the side-to-side curvature that creates a “hollow” and two sharp edges.
Deep Hollow: ROH 4/16” to 6/16” -- better grip, but
slower. Often used by smaller, lighter skaters, high
freestyle, dance skaters.
Medium Hollow: ROH 7/16”-8/16” -- most useful for adults
and medium-weight children and freestyle skaters.
Shallow/Slight to Flat Hollow: ROH 15/16”-16/16” -- goalies, speed skaters.
EDGE: The point at which the side of the blade meets the bottom of the blade.
BURR: A sharp inward or outward piece of the edge caused by stepping on a hard object. Burrs can cause drag.
A long indentation on the edge. If too long,
it can cause loss of control.
