Shapton 1000 grit (14.7 micron) GlassStone

Shapton 1000 grit (14.7 micron) GlassStoneThis 1000 grit (14. 7 micron) GlassStone (50202) is fairly coarse, so is ideal for tasks requiring faster material removal such as initial shaping, establishing primary bevels or flattening the backs of plane irons and chisels. The Shapton GlassStone HR series of ceramic sharpening stones are the most advanced series of stones that Shapton makes they are designed to cut both modern tool steels and high carbon steel very quickly, but wear very slowly,

there are several very good videos on youtube showing how it works

The blade is ground at a skew angle of 30° and with a 25° Bevel

If you order 1 piece of liner

but occasionally red or blue as shown in photos)

and subtract 1° for blades that are 6

with square

Handles have an octagonal barrel shape and are made of beech wood

translating to 80+ years of regular use

A useful trick when checking for flatness is to scribble pencil across the stone and check to see when the pencil marks have disappeared

84 micron) GlassStone (50203) is a fine grit

2mm thick x 25mm long Tool Steel (TS) blade hardened to Rc 62-64 OR a High Speed Steel (HSS) blade hardened to Rc 62

A good choice for boring round 3/4" dog holes in work bench tops
