While I agree cheap files are best avoided, I'm far from convinced advice to spend big money on files is well founded. Ask yourself:
- How much filing will I actually do? (Not much if you own a milling machine.)
- Do I really want to own expensive tools because they will last longer than me?
- Is there nothing else that the money wouldn't be better spent on?
If you want to cough up £30 per file for a full complement of Vallorbe's very best, go for it. My advice is to buy something mid-range.
Far more important to me than owning an expensive file that lasts for ever is having a collection of files in the sizes and shapes I need. Have a look at what Arc Euro sell – aimed at hobbyists, and well described. I have round, half-round, triangular, square and flat in large, medium and small (needle files), more than 30 in total. Mostly second cut, but I have a few rasps for quick ripping and plastics, and a few fine files (smooth cut). I keep a small set for brass only: this is because using a file on steel quickly takes the very sharp edge off, and brass likes a sharp file. When a file used on brass starts to go blunt, replace it and move the old one over to steel where it will still work well.
Horses for courses because this is a hobby! Nothing wrong with pride of ownership purchasing if it makes you happy. I'm the opposite. I think tools are to be used not drooled over. and am quite happy to replace inexpensive tools when they don't do the job. I might go upmarket if I did a lot of filing. As is, files costing about £5 to £10 each depending on size do me well. Paying £6 for a set of four big files is risky!
Never use a file without a handle. Apart from the risk of spiking oneself, the handle makes the file much easier to control.
As a youngster I was given the 'buy quality, buy once' advice by a well-meaning craftsman. Fifty years later I was proved right : my collection of ordinary tools is still going strong. (Mostly!) They've lasted because they're lightly used. A busy professional should buy tools that last, but I'm not rushing to meet deadlines, and only work when I want to. Buying better than I need is a waste of money.
