Edge Sharpening

Having properly sharpened edges in your snowboard can make a big difference in performance, especially on when riding on icy conditions. You will need the following equipment to properly tune your edges: a file holder, a flat file, a gummy stone or pocket stone, a Scotch Brite pad, and a cloth. 

Side Edge Filing:
1) The most full proof method is to use the file holder to assure you of the desired angle at all times. With a file tuning tool you can change the degree of bevel, usually from 0-4 degrees. File down the full length of the edge from one end to the other.
2) If you encounter hard spots in the edge created by hitting a rock, these can be eliminated by slightly changing the angle of the file or by rubbing the spot with the either the gummy or pocket stone.

Flat(Base) Edge Filing:
1) This is to remove nicks and burrs, and to bring the edge flush with the base.
2) Place the flat file on the bottom of the board at a 45 degree angle to the board's long axis.
3) Grip the file flat with the tang in your right hand if pushing the file, in your left if pulling it. Wipe the base down often with the cloth to keep any metal filings from becoming embedded.

Edge Deburring:
1) The edges will feel very sharp due to tiny burrs and striations in the metal left by the file. Use the either the gummy or pocket stone as you did the file to plane down the burrs. Use the Scotch Brite pad at a 45 degree angle to the edge to polish it to perfection.

Edge Detuning:
1) You may detune your edges to avoid "catching edge" and to exit turns more easily. First lightly use the flat file to round off the edges from where they come off the snow forward, towards the tip and tail. Do this using just a few strokes of the file at a 45 degree angle in the direction that the edge runs.
2) Now use the gummy stone to deburr what you have just filed. Bring the stone down in the direction of the board center, just past the snow contact point to blend the job into the sharper portion of the edge.
3) The amount of detuning needed depends on the way you board. Advanced riders or those on ice will need a sharper edge, while beginners or those on soft snow can use a more detuned and forgiving edge. Just remember that it is always easier to dull back an edge than it is to sharpen it.
