No not twisting at all. Regardless of pressure, speed, filing angle etc it chatters bad and barely removes metal. I'm starting to think I got a defective file. OR it could just be too fine for the application. My cheapo round file has been a dream compared to this grobet file. The finish is rough but I just wrap a piece of 400 grit around the file to get an impressionable finish.
In any case I love the shape of this file and I could see it being perfect for impressioning.... I want to order a #2 to see if it's any better but I'm really hesitant considering the 70+ dollar price tag.
Here it is, next to my flat file. I just looked at it under 30x magnification and it honestly doesn't look very sharp. The teeth look like a 60 degree V: ^^^^^^^^^^^^
