A stamped rasp cuts going one way and skates the other, because the teeth are punched up out of a sheet of metal and only one face of each tooth is sharp. Microplane photo-etches more than 400 tiny blades into stainless steel instead, so this file bites on the push and again on the pull. We noticed it on the second stroke: you do not have to lean in, and what comes off looks more like flour than like ribbons of skin.
The working surface is 5.25 by 2.25 inches, big enough to cover the pad of a heel in two or three strokes and short enough to follow the curve at the ball of the foot. The cutting edge sits slightly above the frame, so the file scrapes across the surface rather than digging into it, and that is the detail separating it from the cheaper rasps. Dry or in the shower both work; dry is easier to control because you can see how much has come off.
Two things we did not expect to care about. The handle comes off, which means the file dries flat instead of sitting in a puddle on the shower shelf, and it stores in a drawer without a wet seam. And the steel is rust-proof, so leaving it damp between uses is not the slow death it is for a stamped blade.
It is still a rasp, and a rasp rewards patience rather than pressure: work one spot for much more than a minute and your heel will be tender the next day, so stop while the skin still looks like skin. What sets this one apart is that the surface does not load up with damp skin, so the tenth stroke cuts as cleanly as the first.
Pros
- Etched teeth cut on both strokes, so less pressure
- Large 5.25 x 2.25-inch surface covers a heel fast
- Removable handle lets it dry flat and store small
- Rust-proof steel survives shower storage
Cons
- One grit only, with no finishing side
For most people this is the foot file to buy: the etched surface clears callus in two or three light passes without gouging, and it rinses clean in seconds.
