Hello all. I was wondering about the use of ceramic sharpening rods. I guess they are best used just for touch up sharpening? Are there certain types of steel that they aren't good for? What is the proper technique for their use?

The ceramic rods used by the various manufacturers should be harder than any steel, so they should be able to handle any sharpening job. The only problem they have is that they are set at a fixed angle, so re-profiling might be necessary. This could involve alot of work.

Spyderco has recently introduced diamond-coated rods to alleviate this problem.

The sharpening technique is very simple: keep the blade as vertical as possible and use a "slicing motion" moving from the handle end of the blade to the tip. Don't go all the way to the tip, or you could end up rounding off the tip. Alternate back and forth from rod to rod--one stroke on the left rod--one stroke on the right, etc., etc.

Hope this helps.:)
 
Thaks for the info. However, I don't have one of those sets of two rods mounted in a base with the angles fixed, I just have a single hand held rod. What would be the best way to use that?

Sorry. I just assumed it was one of the dual rod systems. Your situation requires a bit more "technique". I would try to match the factory edge angle, if that suits you and stroke evenly on both sides of the blade.

If you look up at the top line of the page, you'll see "Tutorials/FAQs". Click on it and there is a wealth of info on sharpening by Joe Talmadge, one of our most talented members. (You don't have to pay me until after the first of the year, Joe.:D :D )
 
I luckily scored one of the freebie ceramic rods that Spyderco was handing out to certain folks during the NY show. This has been a very handy thing to have. Looks like a sharpmaker might be in my future purchasing plans.
 
I have a DMT diafold rod for serrations. It looks like a butterfly icepick. Anyway, when I sharpen a knife freehand using this or even the Spyderco Sharpmaker ceramic rods freehand, I will use my chest to stabilize the rod. Basically I will hold the end farthest from me with my left hand, and plant the other end against my chest. this stabilizes the rod, and allows me to concentrate on holding the proper angle with my right hand without fear of the angle of the rod changing. This position also gives me a good view of the edge when pulling the knife towards me. This works very well for me. YMMV.

HTH,

Mike
