hey this will sound a little stupid but what is a “burr” on a snowboards metal edge?
A burr is a deformation of the metal wherein it raises up and causes the serface to not be smooth anymore. If you run your fingernail up and down the edge you can feel it “grab” where there is a burr (be careful, it could cut your finger!). Burrs are especially hard since they are typically formed then the steel edge hits a rock or other hard surface and sparks — the spark forms heat and actually tempurs the steel. Most burrs can be removed easily with a tuning stone, however nasty ones may require a diamond stone.
