HM - great tool. hope you shut down botach pronto.
by the way, something i discovered when using the catm4 (and HM posted this on the catm4 website as well) - not all bolt tails have the same contour and some may not make full contact with the scraping edges on the tool. i found that you can use the OUTSIDE of the tool to scrape the tail as well, and by applying pressure a bit more here or there, will take care of those dimensional differences between bolts. there's a pic in my writeup:
