I got one of these kickstands

http://www.amazon.com/Ventura-Standa...1832435&sr=8-4

Problem is the point of contact with the frame on the kickstand is completely flat, whereas the frame has a little bit curvature. Hopefully, my illustration gets the point across. I would like to cut off the part on the kickstand that is in the way, or at least bend it.

Suggestions on how to do that?
