Yes, I own a Wicked Edge, but its pretty time consuming on most of the knives that I need done, for example the spydercos are full flat ground, it takes me at least an hour to get it sharp by the time I get it set up properly in the jaws. My benchmade infidel double edge is also extremely difficult for me to get set up. I know if I spent more time with the sharpener I would get faster at it. I figure I could just send in 4 to 5 knives at a time and it "might" be cost effective for me as I do not enjoy sharpening them myself anymore... If the cost is too high I will probably do it myself though. My daughter just turned 1 a few months ago so between spending time with her and 60 hours a week at work my time is valuable LOL.
