Sharpening Must Knows

Sharpening Basics

*Skate Blades have two edges, an inside and an outside edge

 

*The portion of the blade in between the two edges is concave, this is

the "HOLLOW"

*The hollow is measured by the radius of the hollow's circle

(as shown above)

*What we perceive as "sharpness" is actually how deep the hollow is

   -The deeper the hollow, the smaller the radius, the "sharper" it feels

*When you get your blades sharpened, the technician uses a wheel that they "dress" - shave to the desired hollow measurement

They then run the blade against this wheel to either deepen or maintain the hollow of your blade

What Hollow is Right For Me?

*Hollow preference is a personal choice and is not related to skating level or type

(hockey vs. figure)

*Most technicians consider the industry "standard" to be 1/2 (one half) inch radius

*A deeper hollow is sometimes recommended for:

-ice dancers

-synchro skaters 

-Hockey skaters who play forward or wing

-Advanced skaters doing high level jumps with minimum body weight

*A more shallow hollow (such as 5/8") is sometimes recommended for:

-Heavier skaters

-Male pairs skaters (who accrue more weight when they lift their partner)

-Defense players who rely on lateral movement or "skidding"

How Often Should I Sharpen?

Figure Skates:

Generally figure skate blades should be sharpened every 20 hours of ice time

 

*Some blades such as Ultima Matrix are made with a stronger metal, so they can go up to 10 hours longer than normal blades before needing to be sharpened

Hockey Skates:

Hockey blades are thinner than figure blades, so they lose their hollow quicker

Hockey blades need to be sharpened about every 10 hours of skate time

Other Contributing Factors:

*Body weight 

- little bodies don't put as much pressure on their edges

*Ice surface

-the colder the rink - the harder the ice surface - the quicker your blades dull

*Nature of skating

-An aggressive forward or wing will dull out quicker than a recreational or leisure skater

-Synchro skaters also tend to lose their edges quicker

*RUST

-If your blades are rusted YOU MUST SHARPEN THEM ASAP!
