MP21-14 Manpa Belt Sander/Power File
Surprisingly expensive for an attachment that will only fit some angle grinders and lacks a backing pad on either side of the belt. Most finger sanders have a backing on one side, this doesn't. Neither does it have a common belt size, so you are restricted to the (again expensive) ones made for it. They are, however, reasonably good quality and don't break easily. The attachment does do a job that is different, but the tight casting with too little adjustment for fitting to larger/smaller mounting collars and the price makes for a very small market.
