Sawfiler Variations include face angle, face length, back angle, gullet width and depth, and a frost notch (if necessary). Typical bandsaw tooth dimensions are 1-3/4" tooth space x 3/4" gullet depth x 3/4" gullet width (grinding wheel width) x 30deg face angle x 16deg back angle. Fitting means tooth dressing and involves swaging, shaping, gauging, and grinding. The tip of the saw tooth is swaged to a flare, then the sides are compressed in slightly with a shaper tool to an exact kerf. Then a final grinding pass is made. The usual gauged tolerance is +/- .005" in kerf, and <
Fleam devices with their right-angle blades are the earliest forms of what collectors now refer to as the fleam. While there are reports of this type of instrument being used in humans, it is more likely that these were reserved for veterinary use, while the common thumb lancet was the instrument of choice for use in people. A survey of 100 fleams found thumb lancets in 6%. These instruments with their triangular-shaped blades were designed to be placed over the vein (most commonly the jugular or saphenous) and struck with a fleam stick. This would ideally result in rapid penetration of
