for a good strop and compound, check out DLT Trading for bark river products. It's very cheap for nearly a lifetime's worth of use and it does bring your edge to a new level, but most importantly, your edge will last longer and it will take just a few daily passes on the strop to maintain it for weeks before you'd have to give it a real touch up on stones. It would extend to life of your blades and the convex it will take with a high polish is quite katana like. pretty sick if you ask me :) I only use the black and white compound, but the white alone does the job plenty!
 
i'm thinking its probably do because your not removing the wire-burr! this was my biggest problem when i first got started into sharpening knifes,and took me forever to figure it out!once it did'i was on my way,but also a proper strop really helps with keeping the knife sharp and not having to return to the stone so often!keep trying .:thumbup:
 
I find a microbevel a very effective way of getting rid of any burr or wire edge. I reprofile to 30 degrees and then do a VERY light microbevel at 40. This will cut off any remaining burr and create a very high level of sharpness in just a few passes. It is important to go extremely light when doing this since the contact area is so small and the force/area ratio is greatly magnified. Once the burr is removed, I continue to resharpen (microbevel) at 40 until it starts to take over the main bevel and then it is back to the reprofile stage. It is more difficult to remove a burr when you are sharpening the entire edge bevel.
 
Still cant get rid of the wire edge, knives get extremly sharp, but after first use, dull again. Under a flash light i can see the wire edge. Ive tried a few diffent steels, cleaning the stones, i use little to no pressure. Still havnt ordered a strop yet. Going to tomorrow. But on my fixed blades i like a toothy edge so that wont fix that problem. Any other tips?
 
Sorry I don't post often, but maybe try a diamond stone ( get mine at w-mart) and try free hand. Keep the stone and knife at eye level go slow and stay with angle of the blade. Maybe this and raise the back of your blade a little to put a microbevel on it, it seems like this recuts the edge and gives a clean slate to work with. Remember it may not be instantaneous and a lot of work.This has worked for me on some tough blades. Seems like simpler is better with some blades.
Not trying to put down the Sharpmaker or other systems like it. I've been free handing blades for about forty years.

I don't really think you need a strop. A wire edge can be hard to get rid of, but I almost never get a wire edge when sharpening on the SM. One other trick is to run your knife edge through some wood as if you are cutting it. The wood can help grab the offending pieces of metal and pull them off. Keep at it. I had this problem once with cts204p and it was driving me nuts. I finally just reprofiled the knife on the diamond rods and put a new microbevel on. Solved the problem and I haven't really had many issues with a wire edge since. Good luck.
