Once you have put an edge on your shovel, how do you keep it from cutting your backpack, or other stuff if you do not use a carrier. I don't want to use a carrier because of the added weight. My ILBE backpack has a pocket and sleeve which is ideal to carry an etool and while the pocket seems sturdy I think over time a sharp edge to cause unacceptable wear.

I think I am going to try the stripping they make to go on the edge of car doors, but i am wondering if anyone has any better ideas.
