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 metal scraper I tried in the past was not real good at wearing down the mold line of the tube. I haven't tried it yet but I thought sand paper would be better at that step, so if you have to patch a hole near the mold line it would be more likely to hold.

also the best thing to scrape an inner tube is one of those foot scrapers for callouses.
