Bushmaster,
Congrats on acquiring an absolutely bombproof blade!!!
One of the great characteristics about INFI steel is that it is really hard carbides held in a relatively ductile (but really TOUGH) metal matrix. This is why the edge will tend to roll when you inadvertantly whack it into a rock or other hard object rather than chip out or suffer other catastrophic failure. That ductility also allows INFI to respond very well to steeling or evening out the edge with a smooth rock in the field, since the metal matrix realigns readily without fracturing off. I have found that if the edge does chip out, INFI answers well to sharpening on ceramic sticks, diamond rods, or sharpening stones.
Strabs gave you the straight scoop on the flat/convex configuration of the Busse edge. As he noted, the flat ground side of the edge (which is the side of the edge you'll strop on the ceramic stick) is the left side of the blade when you're standing with the blade tip pointing away from you and the spine of the knife is upward.
To strop the blade you start with the heel of the knife edge at the tip of the ceramic stick, then draw the blade toward you (edge trailing on the ceramic stick) so that you end with the blade tip's edge positioned near the handle of the ceramic stick. If you've worked with Arkansas stones to sharpen knives before, this process is sort of backwards from that. On stones you are pushing the knife along the stone edge-first. Here you are drawing/pulling the knife along the ceramic rod edge-last.
To help determine if you've got the correct angle as you strop the edge, you can use a magic marker to "paint" the edge of the blade. If your stropping on the stick is removing the marking further up the blade from the edge, you need to steepen the angle between the blade and stick so that you're removing the marking off of just the very edge of the blade. After some practice, you can dispose of the marking process because you'll know the angle by feel.
There used to be a video clip around showing how to sharpen Busse blades. If someone has the URL for that clip, please post it here for us & thanks in advance.
Your in nuclear long-windedness,
Greg
