We will shortly have a number of new converts to the wonders of the Busse Asymmetric Edge. I thought it might be helpful to gather in one place the various users hints, tips, and tricks on maintaining, fine tuning, or improving the Asm Edge. I know there have been scattered posts on this in the past. Let's try to collect all these here in one place.
To make it most useful, instead of posting links, let's copy and post the text here whenever possible.
I'll start with the sharpening tips by Jerry, as posted on Bad Mojo.
quote from Jerry Busse:
"SHARPENING TIPS
***WARNING***
Use the sharpening tips listed at your own risk!
The term Asymmetrical edge does not mean that the knives are chisel ground. All the knives are flat ground, with complete symmetry right to the edge bevel and this is where the Asymmetrical work is done. Hence the name Asymmetrical EDGE. With the blade edge down the left side is flat ground and the right side is convex ground. This edge is both stronger and easier to sharpen than many other grinds.
Method 1
How do you sharpen the Asymmetrical Edge? To maintain the asymmetrical edge, the flat and convex sides should be sharpened in different ways. To sharpen the flat side you need to use a ceramic rod and draw the knife towards you, edge away from you. To sharpen the convex side you can you a leather strop. Sharpening the knife in this way will realign the edge without removing as much metal.
Method 2
This is Cliff Stamp's current sharpening method as follows:
Touch up with strop, first on canvas then leather plus Lee Valley CrO compound if this fails to produce a high quality edge. Turn to a few passes on 800 grit ceramic rod. If this fails to leave an aggressive edge, remove a little more metal so try a few passes on a 600 grit 12" DMT diamond rod. Touch up with strop and if necessary, a few passes on 800 grit ceramic rod.
Afterwhile even this stops working as there will be a visible secondary bevel on the edge. Then back up one step further, Use a SiC wet/dry sandpaper on the convex bevel, Then use a SiC waterstone on the flat bevel. Then use a finer grit of the same & touch up with strop and if necessary a few passes on 800 grit ceramic rod.
Method 3
This last method is to use a buffer / slack belt sander, this method is much quicker if you have the skills.
Method 4
Contact & send the knife back to Busse Combat Knife Co. for sharpening."
