Pair of large Lee Valley conical diamond sharpeners for premium hollow mortise chisels: one for the basic grind, one for a corner micro-bevel.
A pair of large conical diamond sharpeners from Lee Valley for maintaining the premium hollow mortise chisels and bits used in mortisers.
One sharpener is used for the basic grind and the other to put a micro-bevel on the chisel corners. The pair is designed specifically for the size range and geometry of this series of chisels, which runs from 1/4" to 1".
A separate, smaller pair is available for the economy hollow mortise chisels.
Supplied as a pair: one sharpener 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.
