it should be well lapped near the cutting edge. In this lapping process, be sure to 
keep the face of the blade fl at; otherwise, you could gouge the face of the blade or 
create an unintentional back bevel. When you have the back well lapped, polish it 
on a 4000 or 8000 grit stone.

Step 2: Setting the Honing Guide

This honing guide can be set to one of three bevel angle confi gurations. These are 
numbered and color-coded for clarity and ease of use (see 

Figure 3

).

• Position 

c

 (red) for high angles, 

• Position 

d

 (yellow) for standard angles and 

• Position 

e

 (green) for back bevels.

Loosen the blade carrier locking knob, then lift and slide the blade carrier to the 
required position. For example, if you are honing angles between 15° and 40°, 
set the blade carrier to the 

d

 (yellow) location.

You will notice a signifi cant overlap in the bevel angles marked on the registration 
jig. There is no particular disadvantage to using either confi guration unless your 
blade is particularly short (butt chisels for example), for which it may not be possible 
to achieve a lower bevel angle at the high-angle confi guration.
