Pair of Lee Valley conical diamond hones for economy hollow mortise chisels for mortisers and drill presses: one for the basic grind, one for a corner micro-bevel.
A pair of conical diamond hones from Lee Valley for sharpening the economy hollow mortise chisels used in mortisers and drill-press mortising attachments.
The hone is chucked in a drill and sharpens the inside of the chisel's square cutting end. One hone is used for the basic grind and the other to put a micro-bevel on the chisel corners, which need a higher bevel angle for strength.
Suit the Lee Valley economy hollow mortise chisels, for example the 1/4", 5/16", 3/8" and 1/2" sizes.
Supplied as a pair: one hone for the basic grind and one for the micro-bevel.
There are several good ways to sharpen chisels and plane irons: water stones, diamond stones, oil stones and sharpening machines such as Tormek. All give sharp edges, but they differ in speed, maintenance and price.
A honing guide makes it easier to keep the same angle every time. The most important thing is to find a method you enjoy and use often. The guide helps you choose.
Which water stone you need depends on how dull your edges are and how fine a finish you want. A common setup is a coarse stone around 1000 grit to shape the edge and a fine stone around 5000–8000 grit to polish it. For chipped edges you need a coarser stone too.
Water stones wear unevenly and need flattening regularly. The guide explains grits, brands and flattening.
