Micro-Mark ナイロン毛ブラシ（2本セット）

Small enough to tuck into an apron pocket, and the half-inch bristles reach into the teeth of my saw files pretty well. They’re stiff but not scratchy, and the polypropylene handles don’t slip when my hands are a bit oily.

I’ve been using one of these to get the gunk out of my saw blades, and the 1/2-inch bristles reach way deeper than I expected without bending out of shape. The molded handles feel solid in the hand, not flimsy like other mini brushes I’ve tried.

These little brushes are perfect for digging crud out of my needle files—the 1/2-inch bristles are stiff enough to really work the grooves but won't scratch anything. The molded handles give a solid grip too, which I didn't expect at this size.
