Broke my rear derailleur cable yesterday. Bought a new cable at the LBS and proceded to the hardware store to buy cable cutters. Went to two stores and no luck. Went home and tried several types of cutters on the old cable with no luck. Then tried my dremel tool. Worked like a charm! Made several practice cuts on cables and housings. All worked perfectly. So if you don't have cable cutters but have a dremel, your in business. Just thought I'd share my new-found knowledge.
