pulls in the left and right slots of Stage 1 will be needed the first time as you reshape and
sharpen the old edge. Before leaving Stage 1 it is important to examine the knife edge to
insure there is a small burr along one side of the edge.
Figure 3 illustrates how to check for the burr. Proceed as follows: If your last sharpening
pull was in the right slot there should be a small burr on the right side of the blade edge. If
the last pull was in the left slot there should be a small burr along the left side of the edge.
If there is no burr, repeat making pairs of alternating right and left pulls until you create a
small burr along the edge. (Sometimes it is easier to create the burr if you pull the blade
slower.) Confirm there is a burr along the edge after each pull. Only then are you are ready
to sharpen in Stage 2.
STAGE 2
Once you have confirmed that a burr was formed in Stage 1, you are ready to refine the
knife in Stage 2.
Proceed to sharpen in the left and right slots of Stage 2 which have finer abrasive and
sharpen at a slightly larger angle than Stage 1 in order to create a small second bevel
adjacent the knife edge.
You will likely find that only 1-2 pairs of pulls in Stage 2 will be sufficient to create a
small burr along the edge. Always sharpen alternately in the left and right slots of Stage
2, taking about 6 seconds each pass for a 6” blade (see Figures 4 and 5). Take longer
for longer knives, and less time to pull shorter blades through the slots. The burr will
be slightly smaller than you experienced in Stage 1. Pull slower if needed to develop a
detectable burr before moving to Stage 3. You will notice that the edge developed in
Stage 2 is sharper than the edge formed in Stage 1.
Once a burr is detected, move to Stage 3.
