Amazon.com: Swix Ski Edger Pro-Side Edge Tool with Adjustable Bevel: Sports & Outdoors
One Ball Jay Wonton Edge Snowboard Tool 2012: Amazon.com: Sports & Outdoors
I'm between buying one of the two. The swix one is considerably more expensive, but i'd be willing to pay more if it's worth the money. anyone have experience with either of these?
also, the one ball edge guide can only give degrees of 90 or 88. is that a problem? i'm not sure which angle is optimal for what i do (mostly freeride in icy east-coast conditions with a little bit of park)
