Some steel is tougher than others. Comparing say S30V to 440...the S30V is going to be harder to get sharp, but it will stay sharp longer. The opposite goes for something like the 440. Keep what you have but get a Spyderco Sharpmaker. It's the easiest to use in my opinion. Plus you can do lots of other household sharpening with it so it won't be a waste if you switch to something else later. I like to use a hone and a strop on some knives to really get them crazy sharp. Straight razors too. Good secret is use almost no pressure. Just let the weight of the knife do the work. When you pull off, go straight up, don't come off slow at an angle or you'll round off the edge on the way off.
Now...some knifemakers put a convex edge on their blades. To keep it convex without reprofiling, you can't use something like a lansky or a sharpmaker. You can do those easy without spending money by hand using an old mousepad and some sandpaper.
The easiest way to sharpen is never let them get really dull. Unless you're cutting stuff all day long every day with it....a good blade shouldn't get super dull in a day or 2. I know that's easier said than done. Touching up a knife can take less than a minute though.
