I just got two new knives. A mnandi and a large micarta :) I want to touch them up but I dont know what angle to sharpen them at. I have a wicked edge but I heard that that CRKs are convexed. So for those of you who own a wicked edge how do you sharpen your CRks? Thanks
 
Keep the WE and get a Spyderco Sharpmaker / Lansky Croc-Sticks. That's the best touch-up sharpener you can get.
 
I tried just stropping the factory edge, but i couldn't get it to where i wanted it. It was just too obtuse for me (over 20 degrees per side, so it didn't fit the sharpnaker) so I put a v-edge on it with the edge pro (20 degrees per side to start with) and maintain it on a strop. Haven't measured how low you can go before risking to hit the thumb stud with the stones (small sebenza). I'm no expert, though. Still experimenting and learning.
 
Check the angle with a sharpie. When your stone removes the sharpie from start to apex you know the angle, then touch it up.
 
I used a DMT aligner to convert the convex edge on my Umnumzaan to a regular V-edge. The edge from the factory needed to be reprofiled as it was to obtuse for a sharpmaker. For me a V-edge is easier to sharpen and maintain. I use a sharpmaker/strop for touchups and the aligner for full on sharpening. If you decide to change your blade to a V-edge the Wicked Edge would be the perfect tool for the job.
 
I faced similar troubles with my small Insingo. The edge was >20 degrees which meant the Sharpmaker was not good for touch ups. I was doing some light strokes at >20 degrees to keep the edge usable. In the end I put a <20 degree V edge on using my Edge Pro. Now it has been multiple weeks of use and it is still sharp enough to take some hair off my arm. With the new V edge I can do a light touch-up on the Sharpmaker at 20 degrees for a micro-bevel. The new edge seems to last so much longer than the original convex. Could have been a burr that was left on the original grind but in any case it is a great slicer now!

Ditto for me. The factory angle was awfully obtuse and <1mm of an edge. I asked a friend to reprofile it on his WEPS at 30 degrees and it made a world of difference. Now the edge is >1mm.
