Busse dual-grind...

Leo · Feb 28, 2000

Howdy!

Please tell me if I understand this correctly: The "Busse Grind" is asymetrical to make sharpening easier for the user?
Also, do I remember correctly that INFI is tempered to a softer RCH (<58RC), but makes up what it lacks in edge-hardness with very abrasion-resistant carbides?

Thanks!

I thought that was hype when I first read it. I could easily see where it would be stronger as the convex part puts more metal there but as for sharpening a double v ground bevel would be easier, right? Well not exactly. Busse Combat recommends that when honing to use a ceramic rod on the flat side stroking away from the edge. Now you can do this on a double v-ground edge as well but it tends to make a burr which you have to grind off. What happens on the dual ground Busse's is that the convex part of the bevel actually resists the burr forming stronger so there is a greater chance you don't have to work on the convex side. The profile looks like this by the way :

INFI is tempered to a softer RCH (<58RC), but makes up what it lacks in edge-hardness with very abrasion-resistant carbides?

The INFI line is harder, I think the Battle Mistress is spec'ed at 60-62 RC. The Basics are lower about 58 RC.
