I’ve been very pleased with the Swiss pattern Tome Feteira needle files sold by Arc Euro Trade. Cheaper than Vallorbe, and good quality.

Hello Mike,

If in your message you mean that the Tomé Feteira files are of Swiss manufacture, you are wrong.
They are, in fact, manufactured in Portugal.
Read, please, the text you can find ***HERE*** .

Have a look on amazon, Pferd is one of the brands they offer on Prime deals, there is currently one on there that I think is what you're looking for at £3.50 as an add on item meaning you need to spend £20 if you can find a few you want, you can get some at massively reduced prices, I've bought half a dozen pottance files for hardened material ranging from £2.70 to £10 these files retail at about £30 each. Best quality files I've ever used.

Peter F:

Thanks for introducing me to the "pottance file". This seems to be a type of Swiss or toolmaker's file with the cut designated by a number and, as you suggest, harder than standard.

In trying to chase this down I came across a reference to Peter Stubs' files being measured in French inches or "pouces" (longer than the English inch).

Just a point but if I was filing a square hole I would use a three square file ( triangular ) not a square one

Yes, they range 0 to 4, 4 being the finest, a #1 pottance is about the same as a normal fine file, and a #4 you can file your finger nails with its so fine.

That used to be the case many years ago but now the French pouce (thumb) is defined as 2.54 mm, exactly the same as the Imperial inch.

Thank you for pointing that out. My 1943 Machinery's Handbook gives the then metric equivalent of 25.4001 but, according to Wikipedia, " In 1930, the British Standards Institution adopted an inch of exactly 25.4 mm. "

I remember having a discussion some years ago with an elderly relative who was a qualified engineer and having some difficulty in persuading him of your point. The difference must have been regarded as very slight and I think the use of a 127 tooth gear for metric pitches pre-dated harmonisation.

Agree with Peter F, Pferd are fantastic files. I have quite a few and some are years old and still cut very well even though they have seen a lot of use over the years. Top notch filesyes

Sorry to be a pedant but that should be 2.54 centimeters or 25.4 millimeters.
