If you are frustrated by your current drywall rasp, Tajima Tool might have come up with a better one. Their 7″ long Combination Drywall Rasp has three different clog-free sections for shaping, beveling, and spot grinding.
Tajima Tool’s special chrome-plated Tetra-teeth supposedly won’t clog and cut in both directions, which makes the tool faster — plus you don’t have to figure out which way to orient it. To improve your grip on the rasp, they’ve embedded elastomer into the handle.
The first grinding section is recessed to hold onto the edge of the drywall and has coarse teeth for quickly shaping or trimming it. The section also has openings to catch some of gypsum in the handle. The second section has fine teeth for beveling or smoothing the drywall edge. The last section has side-rail teeth for notching and detail work.
Pricing for Tamjima Tool’s Combination Drywall Rasp starts around $13 before shipping.
