Pictured are a set of files that I got from Rings and Things. As you can see from the picture, they have become my favorite and are well used. Smaller than most files they are a must have for working with PMC. Because of their petite size, they are wonderful for getting into tight spaces. They are only four inches long and the smallest round file is only 2mm at the widest part. I had them at a PMC class and everyone wanted to borrow them.
The set is by Eurotool® and features a fine grit diamond electroplated onto high-grade stainless steel. The set includes round, half-round, flat, three-square, square, warding, slitting, oval, knife and barrette. You can order them here.
