Overview
Short, double-ended files bent into a range of curves, so the cutting surface can be worked inside a concavity or around a detail. Rifflers are how the transition between two forms gets smoothed, and they are the primary shaping tool for the softer stones — alabaster and soapstone are worked almost entirely with files and rasps.
Using it
- Use a drawing motion, lifting on the return stroke — files cut in one direction.
- Match the profile to the curve. A round riffler in a flat-bottomed groove will only scratch.
- Card the file every few minutes. Clogged teeth skate and scratch.
- For alabaster and soapstone, a coarse rasp followed by finer rifflers replaces most chisel work entirely.
Safety notes
- File teeth are sharp and the tool is short. A slip puts the cutting surface into your hand.
- Stone dust from hand filing is fine and stays airborne. A mask and extraction still apply.
- Steel files wear out silently. A dull file burnishes instead of cutting and can crack soft stone.
