Knife not getting sharp?
•
More strokes
- Grind all the way to the edge. Continue until a burr is raised. Then
progress to a finer belt.
•
Higher Speed
- Slow belt speeds may not be removing enough material.
•
Coarser Belt
- Coarser grit belts will remove material more aggressively.
a) Problem: The tips of my knives are becoming rounded. See Section 5.
Solution 1: Stop the tip on the belt while powering down the tool.
Solution 2: Keep the blade edge perpendicular to the belt. To reduce tip rounding,
follow the curve of the blade.
b) Problem: The belt is cutting into the sharpening guide or edge guide.
Solution 1: Use the belt tracking lever to re-adjust the belt position to center
of the pulley.
c) Problem: How do I feel for a burr at the cutting edge to know when to proceed to a
finer belt?
Solution 1: Slide your finger perpendicular and away from the cutting edge. The burr
will feel like a small ‘ridge’ or ‘wire’ at the edge.
d) Problem: My knives are cutting through my edge guide.
Solution 1: Use much lighter pressure on the Edge Guide. Using only the weight of
the blade provides best results.
Best Techniques:
Only use P120 on blades with edge damage, thick / wide edges or very hard blade
steels (D2, S30V, 154CM, etc.). This belt will remove material and raise a burr very
quickly. Use sparingly and check for a burr after every stroke.
