Some time ago in a second hand kit I got off eBay were 4 Micro needle files which I have found exceptionally useful for preparing rail ends to fit chairs. I have added 2 standard needle files in the photo to show the differance
2 x 1.5mm square profile
2 x 1.5mm round

The files are just under 14cm long, cutting surface 60 cm long, the handles are 1.85 square and 8.5cm long
Any thoughts please what these files are called and where to buy them please
