Well I have been gathering up a collection of Bear razorheads, and just picked up a half dozen of the Rothaar snuffers. All of my razorheads have been used or are NOS. The snuffers are NIP but the inside of the ferruls on all of the BH's in question have either glue on them or they are rusted slightly. I don't think the glue is a big deal but the rust is something different, I have been looking all over for a tapered wire brush to clean the inside of the BH out. I can't seem to find what I'm looking for. Any suggestions as to accomplish my goal? Thanks in advance.
