The DiaFold Diamond Flat File is a tapered single sided sharpener that fits where other sharpeners can't. The 1/16" thick diamond "file" tapers from 1/4" wide at the tip to 3/4" at the handle. Diamond is one of the few abrasives able to sharpen carbide so the thin shape of the DiaFold Flat File makes it a natural choice for sharpening router-bits.

We always knew these would be a specialty purpose sharpener, and we had initially bought a couple DiaFold Flat Files to try them as an alternative method for sharpening auger bits. They're a little too wide for bits smaller than about 1 1/4", but we found the thin profile, and diamond abrasive to be useful in tight spots too narrow, or too hard (like carbide) for a mill file. You won't need this sharpener all the time, but when you do, it's likely to be the only tool for the job.

Dimensions: Abrasive surface measures 4 1/2" by 1/4" by 3/4" and is 1/16" thick with a 5" long handle. Folded dimensions are 5" by 1 1/4" by 7/16"
