A blunt file rounds the work instead of cutting it; this simple truth underscores why investing in quality files is non-negotiable for any serious engineer’s toolkit. Cheap multipack files from high-street DIY racks are made from soft carbon steel that wears down after a few uses, rendering them useless for precise tasks. In contrast, trade files from brands like Bahco, Vallorbe, or Pferd utilise high-carbon tool steel that retains its cutting edge over years of use. This durability comes at a higher price point - typically ranging from £10 to £50 per file - but the longevity and performance justify the cost. For those in the UK engineering trade, choosing between economy and efficiency means opting for reliable tools that can withstand daily workshop demands without breaking the bank.
How we picked these
- Cut grades: bastard (coarse), second cut (medium), smooth (fine), dead smooth (very fine). A working set spans bastard + second cut + smooth.
- Profile: flat, half-round, round, square, triangular cover most engineering work. Needle files for delicate work.
- Length: 200mm (8") is the workshop standard. 150mm for smaller work, 250mm-300mm for larger.
- Steel: high-carbon tool steel, properly hardened to 64+ HRC. Soft files dull in days.
- Origin: Bahco (Sweden), Vallorbe (Swiss watchmaking), Pferd (Germany), Nicholson (US/Brazil). Avoid generic Chinese files.

Frequently asked questions
What does 'cut' mean on a file?
Cut grades describe how many teeth per inch - bastard cut has 25-30 teeth/inch (coarsest, fastest material removal), second cut has 30-40 (medium), smooth has 50-60 (fine finish), dead smooth has 80+ (polishing). A workshop set should span bastard + second + smooth at minimum.
Why do trade files cost 5x supermarket files?
Three reasons: (1) high-carbon tool steel properly hardened to 64+ HRC vs supermarket files at ~50 HRC; (2) precision-cut teeth with consistent geometry vs stamped teeth with variable spacing; (3) properly heat-treated tang that doesn't snap when handled hard. Trade files cut faster, last longer, and break less often.
Do I need a file card?
Yes if you file soft materials (aluminium, brass, mild steel). Pinning - material wedging between teeth - destroys file performance until cleared. A file card (brass-bristle brush) clears pinning quickly. £8-15 and lasts forever.
Bahco or Pferd?
Both are top-tier trade brands. Bahco is more common in UK distribution and slightly cheaper. Pferd is the German metalworking standard with stronger reputation in precision/aerospace work. Either is correct for trade workshop use.
Why does my file slide instead of cutting?
Three causes: (1) file is loaded with pinning - clear with a file card; (2) file is dull - replace; (3) wrong file for the material - for non-ferrous (aluminium, brass) you need a coarser file with chip-clearance design like Pferd's 'aluminium cut'.
