Pocket watch cleaning pens

[binman]

The pens are retractable, two are wire one is glass fibre, which cleans very well, no scratching, the wire are pretty good to, now best way to trim the glass fibre strands, I can use side cutters for the wire, I did try my Stanley knife, but strands very strong.richard

Sounds interesting. I'm a clock guy, but I'd love to see some pictures of these.

I think this is what is being referred to. The fiberglass insert is only 1.75mm thick, offering better accuracy than the old fiberglass brushes.

Thanks Dave. What is this used for?

Thanks Dave. What is this used for?

Back in the 1950's, I bought a red plastic holder with a glass fiber brush that was screw-fed. I think they were meant to be erasers for ink and typewriters. But I saw them in the Swartchild catalog listed as rust removers.

Dang! I never saw Jim's follow-up question. Yes, I use it to remove surface rust off of small parts. For example, a balance staff that has perfectly good pivots but might have some light rust on the body.
