AT-FX01 is a flat DSPIAE hand file with a different grit on each face: #400 for shaping and #800 for the first round of smoothing, both double cut. The body is 420 martensitic stainless steel with a DLC coating over the whole surface, so you can rinse it under the tap without it rusting, and the grit numbers sit under the coating where they will not wear off. The narrow sides have no teeth, so they will not mark the neighbouring face. It suits ABS, polystyrene, resin and epoxy putty.
#400 and #800, double cut
165 × 10 × 2 mm, 25 g
Comes in a black protective sheath; store it there after use
Not for iron, aluminium or other hard metals, nor soft metals such as tin or gold
Brush lightly along the teeth to clean; no wire brushes. Not for children under 14

Notes · Q & A
What's the difference between a needle file and a sanding stick?+
Needle files are steel, cut faster and hold their shape for tight spots and metal. Sanding sticks are foam or paper-backed abrasive, kinder to plastic and better for smoothing broad, flat surfaces without gouging.
Which grit should I start with on mould lines?+
For plastic, start around 400 grit to knock the line back, then refine with 600–800. Coarser than 400 leaves scratches you then have to chase out, so only go lower for resin flash or heavy work.
Should I file wet or dry?+
Wet sanding with a drop of water reduces dust and clogging and gives a finer finish, which matters on resin where the dust is best not inhaled. Dry filing is fine for quick metal work and steel needle files.
How do I stop a file clogging with plastic or resin?+
Brush it out with a stiff brass brush along the cut direction. For sanding sticks, tap them clean often. Clogged abrasive stops cutting and starts burnishing, which just polishes the high spots rather than removing them.
