A taiko player must take good care of their bachi to protect both their hands from splinters and the drum heads from excess wear from sharp, rough tips. A supply of various grade wood sandpaper will assist in the proper maintenance of bachi. Use 100 grit to begin with to sand deep grooves and sharp edges then finish off with 150 to 220 finer grit for a smooth, polished stick. Sanding also removes dirt and dark spots from the drum stick tips which inevitably builds up after prolonged drum playing.
Long & McQuade music stores carry affordable taiko drum sticks which are suitable for using on larger barrel drums with thicker cowhide heads. Purchase various grade sandpaper at any hardware store.
