The crimp ends come right off with a solid yank with the side-cutters. Crimp a new one on when you are done. The side-cutters I have have a crimper built into them. I always have a side-cutters when I work on anything. I guess it is an electrician thing.

I fail to see what the big deal is with these crimps. They cost something like $.03 each when you buy them in bulk. Often you can re-use the ones you yank off anyhow. A bottle of 500 should last any home mechanic a lifetime. It's like ferrules, oil, grease, a variety of bulk bearings sized in jars, or any other consumable used when working on bikes.
