Caution! Sharp! Schlumpf chamfering tool

 

What do Swiss bike gearing systems and American solar-lit bongs have in common?

In Chico, CA, it seems to all make sense, as, after a good 16 years chamfering bottom-brackets for Schlumpf installations, our old chamfering tool just wasn't cutting the metal like it used to. After searching high and low in Sacramento (unsuccesfully) to find someone with the tooling to set a new keen edge on the cutting tool, we finally found the right guy in Chico.

Clearly, searching low was not the right approach, but Tom took a break from marketing his latest (patented) invention in order to rejuvenate the Schlumpf tool.

Thanks, Tom, and good luck marketing your invention.
