The Diamond Needle Files Set is perfect for my steam engine workshop. The files are "sharp" and small burrs can break very well. And since there are 10 different forms, is something for every application. The grip rubber coating is ok - the handle to be very thin, however, so sometimes the secure grip is lost. The sleeve may be somewhat greater calm - not everyone enjoys it, the file from the super tight plastic-part challenge or hereinzufummeln. But what do you expect for the price? With better grip and better cover the filing would have been significantly more value to me. Degraded due to handle and sheath.
