This has been very helpful. Thanks to all. It's not going to see much use, but I do have a few bikes that I work on and I change the cables and housings on all of them about once a year. I've been using a bench grinder to cut the housings, but the heat generated melts the plastic lining, which tends to gum up the opening. It's hard to ream it out, especially with longer runs. Just thought it would be nice to have the right tool for the job.
