Sharpening is definitely a good idea... I often find lures (brand new) have somewhat dull hook points. I believe in sharpening all hooks now and then. I keep a simple "pen style" sharpener on me when fishing. Very similar to the one below. It costs like $7 and the one I have has been in use for about 16 years now. Small price in comparison to time used and amount of better hook sets it has provided.
Walmart also sells a sharpener similar to that called a diamond edge pen style sharpener, can be used for knives also and works very good, i use it for my hooks and my hunting knife's and it leave a sharp hook and a nice edge on a good knife.
