RE: RCBS case trimmer, can you sharpen it
most everyone uses a lowcarbon steel and case hardens them for a case trimmer cutter. Often times the employees sharpening them at the factory over sharpen them and they don't stand up. There's usually no chance of sharpening one of these cutters where the hardened edge is gone.
Get a replacement.....or better yet....look to L. E. Wilson case trimmers
