I've got a very nice and expensive set of knives that's taken a few years to put together. I thought the knives that I first got were still quite sharp until tried the the newest acquisition, which was like a razor, reminding me that my older knives were once that sharp. So I want to sharpen my knives. I've sent cheaper knives to be sharpened in the past and they lost their edge rather quickly. I've also sharpened the cheap ones myself, freehand, using a whetstone and actually got great longer lasting results after a couple mistakes. I feel a bit hesitant doing the same with the expensive ones. I'm good at doing stuff like this but I want a little more assurance. Can anyone recommend a reasonably priced manual sharpener? I've done a lot of research and am overwhelmed at this point. At this point I'm leaning towards the Spyderco Tri-angle model. Is this as good, easy to use and foolproof as I've read? Thanks for the input, Happy New Year!
