The Pinpoint-Hooks "Fine File" is the perfect addition to the other tools in the range. The manufacturer says "This file is perfect for experienced "sharpeners". The diamond coating results in the most precise hook points I have ever seen produced by hand. Personally I use it for hooks size 2-10."
For beginners they recommend the "standard" diamond file, (product code
17666) because it will enable you to achieve great results much faster!
