Knife files are tapered in width and thickness, but the knife edge has the same thickness from point to shoulder.
They are cut on both sides. Can be used to file in a slot or wedge shaped opening. The curved knife edge allows for easily filing in restricted areas.
Swiss made Glardon Vallorbe® half round needle files have round handles.
Needle file lengths are measured from tip to tip including the handles. Measurements given are at the thickest point.
