What the AI looks for in American Pattern Files
- Cut grade
- Bastard for fast removal, second cut for general work, smooth for finishing. These three grades are how American pattern files are sold and chosen.
- Length
- At the same cut grade, a longer file is coarser; buy shorter for finer work. Tooth spacing scales with length in American pattern files.
- Mill vs flat
- Mill files (single cut, slightly tapered) for sharpening blades and draw filing; flat files (double cut, tapered) for general stock removal. These are the two most bought shapes and they are often confused.
- Safe edge
- Pick a file with an uncut (safe) edge when filing into a corner. A safe edge keeps the adjacent face from being damaged.
Brands that matter
- Bahco: Consistent American pattern files in common shapes.
- Pferd: Also makes American pattern files with good tooth quality.
- Nicholson: The classic US name; check origin, as consistency varies.
- Simonds: Long-established American file maker.
What to avoid
- Bargain sets where all files share one handle-less tang design and soft teeth.
- Using a bastard file for finishing, which leaves deep scratches that need more work.
