Back 35 years ago I did a lot of hand metal finishing in a shop where no one used that people commonly think of when it comes to metal finishing, which is the single cut rectangular file that screws onto a wooden handle that looks like a planer or a threaded turnbuckle thing that could be used to bend the file.
The ones I'm thinking of were double cut with a tang and about 12 inches long... coarser than a bastard file.
Anyway, I know this is a shot in the dark, but if anyone knows what I'm talking about I'd like to know where I can find one of these... I've Googled "solder flow file" and came up empty. When I Google "metal finishing file" I get a lot of hits but vendors don't list anything by the name of Solder flow file so it's possible they go by another name, and the pictures are so vague I can't see what they look like.
Any help is appreciated.
