T-H-E must have file for metal clay. Perfect size, large, heavy medium-cut file, great for re-shaping clay quickly.
Whilst having enough tooth to quickly remove material, it is still fine enough to not leave your surface shredded to pieces. As it is a nice long file, it is comfortable to to work with. (Another of Petra's favourite tools...)
Half-round, this file has one flat side and one concave side.
The file is 12mm wide at it widest part and 22cm long.
