I have a LOT of knives, so need a bigger stone at times.
If you look at the pic, you will see a very large 2-sided stone in the back. I don't remember the grits. It is fine/course.
Under it, you will see a yellow Schrade diamond impregnated sharpener. I use this on pocket knives all the time. $15 well spent. I have used the [beeep] out of it.
Straight to the right of that (next to the 22° jig) is a simple Arkansas stone. It is a medium to fine grit. That and a extra fine grit Arky stone(below it) will take care of 90% of your needs.
Some form of quality leather strop is also nice to have.
I do not own any electric sharpeners, or fancy sharpening systems. It took some practice over the years, but I am able to get a quality edge on most anything without these items. Practice is all it takes. You also need to learn how to do it without scratching up the blades. This takes practice also, but it will come to you.
Buy a crappy new model Schrade or some other Chinkwanese steel knife. They are very hard to put a good edge on. But they will teach you how in the process. (I'd start out with a fairly straight blade. The more curves, the harder to sharpen.) If you scratch it up, so what? Who cares?
