Like everyone else, we are suckers for hand made rasps. These Gramercy Tools rasps are hand cut and you will be surprised not only by how fast they work, but by how smooth a surface they leave. Made of surgical grade stainless steel for a tough, long life with a brass ferruled wood handle. The lengths given are the approximate working length of the rasp. "Teeth coarseness" is the approximate number of teeth per inch of the rasp teeth. We have several sizes of rasps designed to cover a wide range of work. The shortest of the rasps is only 5" long (working length) and is inspired by the long-gone Nicholson 55 - except ours is hand cut. The teeth go out to the edge, for a greater range of work. We have longer rasps with both coarser and finer teeth. The larger, finer rasps are ideal for making cabriole legs and other areas of sculpted furniture-making. The rasps are made in Pakistan, which has a long tradition of metalwork, by a single craftsman with very limited production who is working to our specifications. Sizes will come in an out of stock as supply permits. The handles are made in USA.
