I just got my book that I ordered through Amazon titled, "Zinn and the Art of Mountain Bike Maintenance" by Lennard Zinn, for ~ $16.50 (free shipping).
I started to read it from the beginning. I'm in the chapter on tools, level 1. One of the items that he recommends, but doesn't explain why is that for a patch kit, he prefers one w/ sand paper instead of a metal scraper.
Does anyone know why he would say so? How about you? Have you found a difference in the ease of patching a tire (and it not exploding or losing the patch) with either material?

The reason that you clean off the patch area is to rid the tube of the wax mold release. The metal scraper doesn't clean off the tube very well and it is possible for the patch to leak around the scratches though obviously it doesn't happen very often. The sandpaper does a vastly better job with less rubber loss.

As a bonus, the sandpaper can be used to level and deglaze brake pads.

Metal bits can make rattling sounds and the possibility of cutting edges from metal items in your kit is nice to avoid if possible.

The reason has been explained here often. The cheese graters with some patch kits (Monkey Grip) are just that and do not prepare a good adhesion surface. This is an item that demands an FAQ item because it is so readily misunderstood. As I have mentioned in this forum, even the REMA patch representative at InterBike had no idea about this or why freshly mounted patches delaminate easily.
