The blanks are forged and ground; manufactured with an exact cut of even density and depth using special machines. These non-convex files have tooth profiles appropriate to each grade of file.
To protect the files, the set is arranged in a strong transparent roll-up nylon wallet.
Protected files cannot be contaminated and the cut is protected against damage; this ensures a consistently high removal rate, smooth file surfaces, and an extended working life.
With impact resistant plastic handles.
