Video Instructions for sharpening your BBK ACE knife
Our Recommended Method of Sharpening
This is the same method we use in our shop to put the factory edge on your ACE knife.
Using a Spyderco Tri Angle Sharpener :
Place the course stones in the 40-degree openings.
Use the flat side of the stones only, apply 10 passes to the flat side of the knife and 2 passes on the beveled side of
Now repeat the process using the fine rods with same 10:2 ratio.
Strop the blade lightly using a strip of leather.
Your *ACE* knife should now be as sharp as it was when you purchased it.
Every fifth or sixth sharpening we recommend using the 30 degree back bevel openings using the same 10:2 stroke
ratio to help the blade retain it’s thin superior cutting edge.
When sharpening and nearing the point, keep the point in contact with the flat of the stones. Allowing the tip of the
knife to roll over the edge of the stones will cause the knife point to become blunt.
Using Conventional Stones
Conventional sharpening stones can be used to sharpen your *ACE* knife.
Unlike conventional knives which require equal amounts of steel to be removed from both sides of the blade – Black
Bear *ACE* knives require that most of the steel (80-90%) be removed from the flat side of the blade.
Holding the flat side of the knife against the stone at a 20-degree angle, take approximately 10 passes over your stone.
Check for a burr on the opposite side if the knife edge.
Continue honing and checking until you can feel a burr along the entire length of the knife.
Now flip the knife over and sharpen the other side of the knife at the same 20-degree angle.
Only a pass or two on this side of the knife, enough to remove the burr, is necessary to regain the superior cutting
ability of your Black Bear *ACE* knife.
With the burr removed, strop the blade lightly using a strip of leather.
