Snowboard Edge Tune Explained - Snowboarding Forum

If I have a -1° base edge and 1° side edge the board will have a 90° edge. So if I take a file guide for shaprning the edge, to maintain that 90° angle should the file guide be set to 91°?

Your picture is correct.

obtuse 91 = acute 89

i made the picture i was just making sure i need to set the file guide to 91 degrees. to maintain a 90 degree edge.

Be careful, some guides use acute angles, other use obtuse angles.

wait, what? i guess i have no idea how that stuff is measured.

Actually what I'm saying is that an obtuse 91 is identical to an acute 89.

It depends on how the edge tool manufacturer decides to label their stuff.

Although most basic edge tools (i.e. Dakine Edge Tool) use acute angles.

The main source of confusion arises when the angle gets labeled as 1 or 2.

Yep but if you say 1 degree on the base and 1 degree on the side the shop will know what you mean. I don't think I've ever heard anyone ask for a 91 degree side bevel before. But you are right.
