Get a basic stone, a cheap knife and learn how to use the stone. Recommend a DMT diamond bench stone or a DMT folding stick. I have a lansky and I use it for previously abused knives that some moron figured out how to put 10 different angles into. I normally use a DMT stick, regular Arkansas stone, diamond pocket stone, side of leathe boot, porcelain sink, bottom of coffe cup(unglazed ceramic ring), whatever. Recent favorite was ceramic core of defunct aquarium heater, it was a foot long ceramic rod with four nice sharpening surfaces. Got my filet knives so sharp I barely felt it when one went halfway through my finger. Dropped rod, it's broke.
I say learn the stone because then you can use anything. The key is consistent angle, the right pressure and good pattern. The heavier the pressure, the more the stone cuts. Lighten up as you finish for finer edge. Pattern. If you make ten passes on one side of the blade you now have a wire edge rolled over the other side, not good. When doing heavy blade repair I sometimes stay on one side awhile, but then do the same on the opposite side.
Break the final wire edge by stropping on leather. If it easily lifts hair, it's sharp. Get into this sharpening thing, and you'll look like a freak as I do. I ran out of hair on my right arm so I had to go after a patch or two on my calf. If I get any more knives I'm gonna lose my eyebrows.
