In answer to your question: yes.
I sold Cutco for about 15 minutes and got a knife called the "Fishermen's Solution" that has a hook whetstone on it. I saw a Lefty Kreh video once that said if you try to drag the hook across your thumbnail and it doesn't stick, it's not sharp enough. Quick and easy test. Sharpening takes all of three passes from three angles, like pill mentioned.
