with that being said , what can you do if a game doesn ' t use raw input ? edit figured it out , thanks everyone . <| sep |> How much you need to do depends on the base angle your board has from factory , and then there is finding a balance between not catching an edge on rails and still having good edge hold for normal riding . If you are lucky you might have a board that has a 3 degree base edge , and you might not need to do much at all . If it is a 1 or a 2 degree base edge you want to take a bit more off . With the board upside down , I run the file down the edge between the bindings at a slight angle , and take off enough edge that you can feel a difference from the sharp factory edge . The more I take off , I add more angle to the file to slightly round it more and more . Once you have done it a few times , if you are still worried take your board off , and run it by hand over a metal rail , and listen to the sound it makes , if you don ' t hear the metal on metal sound , you should be all good . It ' s a bit of a trick though , because once you give an edge a good detune , it is very hard to get it back , even with heavy base grinds . If you have a workshop near you , you could ask them for a tune with a 3 degree base edge , it will keep the edges out of the way for rails , and you will still have nice sharp edges for normal riding .
