Having bought a nice new set of files (link below) I had to make handles for them, I chose iroko because I had some and it is cheap, copper pipe on the ends and a profile cutter made from a bit of caravan!
Files were purchased from Proops brothers, I am not affiliated with them or anyone else but am happy to say these guys have a good range of products for craft and hobby metal working covering budget tools like these up to Swiss made files at £50 each!
