Fine, Medium and Superfine hones.
Their smaller size and tapered profile makes these high quality hones ideal for renewing the edges of hard to sharpen tools like router bits and circular saw blades. Super hard diamond particles bonded to a wafer thin metal backing plate, can handle all of today's extra hard materials- even carbide. 5 - 7/8" long overall with a honing surface of 2" long x 3/4" wide.
