Yeah I decide to reprofile my ZT560 to 20 degrees using the spyderco sharpmaker coarse ceramic.... Took about 30 minutes on one side which was set to approximately 22 degrees while the other side sits at about 26 degrees.
The 26 degree side, 1 hour into preprofiling, and still not even 1/4 of the way there.

Ordered some spyderco diamond stones coarse stones, hopefully they help.
 
Yea the sharpmaker to me at least is just to touch up knives. Reprofiling on it is really hard as it has it's limitations.
 
I have not but they more than likely speed up what ever you're trying to do with the ceramic rods. Thinking in learning freehand instead of following a preset guide.
 
I use my lansky to reprofile then I hand finish after I have a nice bevel established. It takes a while with uneven factory bevels on cheaper knives or harder steels of higher end knives, but I don't have diamond either. I'm considering a small belt sander in the near future.
 
I've reprofiled several times with my Lansky. It gave accurate enough results, but took a looooooooong time before I got the diamond hones. The extra coarse and coarse made fine work of a 3V bushcrafter that needed more acute angles for best performance.

Damn man, thanks for the advice, just noticed the difference is only $7. I went ahead and ordered the DMT Aligner.

Glad to be of help. :D

You'll find that reprofiling goes faster with the aligner kit. Once you've reprofiled, it will be a breeze to maintain the edge with the SM. Enjoy!
 
Yep. I've tried to reprofile with the Sharpmaker. That's gonna take the patience of a saint. Plus you hand is really gonna be aching by the time you get anywhere. I tried to go from what I am going estimate at 21 degrees to 20 (on a side) on M390. I went at it for an hour and gave up. I took my DMT and propped it up carefully against the sharpmaker stone and in about 5 minutes I had it. The other side was spot on 20 degrees.

The key with the Sharpmaker is to get you knives "indexed" to it with diamonds or some other method and then touch up often.
 
Thanks Hoosier.

I don't mind spending a long time, but I am not doing that with a folding knife, I'd rather hand polish my tantos or sword.
 
I reprofile my folders with the Wicked Edge, then polish them up with my paper wheels. Took about a half an hour to take my GB to about 30 degrees inclusive and polish the edge. Now if I had richardj's skill, I'd do it all on my paper wheels and be done in less than 10 minutes.
 
I have a flat SiC stone that I clamp to the Sharpmaker and then I adjust my angle by hand. Has made short work of all the steels I have used it on. And that is reprofiling the edge to about 13* or so.. So I shouldn't have a problem with more wear resistant steels either. Besides CTS being up there in the wear resistant category anyway.
