I have the trusharp and the hand held one by Dritz. Both work pretty good for me. Remember to use a little bit of sharpening oil, and for the hand held one, use the course side first and count the times you go around on one side and do the same amount on the other side. Then use the fine side to finish off the blades. Neither one will take out nicks and your blades will never be as sharp as new, but will last way longer. Don't wait til the blades are completely dull to resharpen, I take a few mins. between two or three cutting days (I cut something almost every day) and touch up the blades.
