This is one of the reasons I started this thread. I'm not sure I know enough or have practiced enough to tell myself very much. I've got about $70 invested into sharpening so far, having a 600 and 1000 grit flatstone and I was given a Lansky. I'd like to be able to quickly reprofile and sharpen a knife with repeatability. I'm not good at what I have and I think repeatability and speed are lacking in what I have.
There's a lot on this site and there are pros and cons to everything, so it's hard to know what to go with. Sometimes when I think I would like one system, I would read a thread that shows some cons on it so I kind of get back to square one a lot. Where I'm at right now is it seems a bench grinder with a paper wheel is the fastest, and the Wicked Edge would be the best for repeatability, but it's too expensive.
I'd like it to be simple, inexpensive, and quick to be able to reprofile and sharpen, but I don't currently know how to get repeatability with those criteria.
Right now, I would tell myself: be patient, it's not quite a simple as you would like it to be, it may cost more than you want it to cost, it doesn't have to, but it might, it may take more time and practice than you want it to.
Thanks everyone, keep your thoughts coming please! It would be good if this could be a thread with collective, experienced wisdom summed up for new people coming to the site.
