These replacement miter trimmer blades are made from high speed steel, and pre-honed ready for use with you hand saw. The low-bevel, combined with a skewed cut, results in a silky smooth finish and the tightest possible joints. The blades can be resharpened many times, and they are easily removed for sharpening. For use with your guillotine-style miter trimmer (#26477, sold separately). Note: Blades should be honed on the bevel side only. Mounting hardware not included.
