Tool Good Quality Files and where to purchase them?

[StevSmar]

I've found an answer:
"Example: At a length of 250 mm, a cut 1 file has 9 teeth/1 cm of file length. A 100 mm long cut 1 file has 17 teeth/1 cm of file length, however. The higher number of teeth on shorter files ensures the same ease of use (in terms of force input, guidability and stock removal rate) on surfaces and edges as for longer files."

So this explains why my small files are listed as a Bastard cut.

Now I just need to develop a list of the files I want to order!

Just to add to the confusion, this is what Starrett & Co said in the 1917 Starrett Book for Machinists Apprentices.....

I stopped off at a distributor yesterday that stocks Pferd files. They had a few oddball files in stock plus 14” tapered bastards.

The coarseness is a big change from my 10” bastard and is it ever thick. You could say it’s a fat bastard for sure.

So far so good, it’s given me confidence to order a couple of others.

I’m sure pleased the forum helped me work out what the hell a bastard file is. Life would be a lot easier if everyone just did as I asked- but less interesting…
