Who doesn’t have a Stanley’s Surform file or plane somewhere in their shop? While these tools work well for some tasks that require a rasp, with Microplane’s replacement blade they might work even better.
Microplane’s Surform replacement blade fits 10″ Surform files and planes. They claim their 400 series stainless-steel blade cuts 10x faster then similar replacement blades.
Rather than abrading the material and creating sawdust, the Microplane blade shaves the material, leaving only small shavings behind. The blade works on wood, plastic, rubber, and other materials you might take a rasp to.
The Microplane replacement blade retails for $14.
