These knives represent an array of sizes. Your choice depends on what you're going to use the blade for, how and where you're going to carry it, and how much you want to spend.

On the small side, you have the Kershaw Silver Spur. You can carry that little beauty anywhere on your person with no bulges. On the larger side, you have the Spyderco Endura. I have always wanted the Spyderco Delica, myself. It's a little smaller and easier to carry.

I love to have a larger Spyderco with me on a trip to a national park. I have the Cricket and Dragonfly. I always have a problem chosing which to take.

The Spyderco Endura or Delica should handle any cutting chores you ask of them, but you would not necessarily want to deploy either of them in the middle of a grocery store to cut a pesky thread. You'd scare the PHRASECENSOREDPOSTERSHOULDKNOWBETTER..

I have no problem pulling out the Kershaw Silver Spur in such an environment. I can have the knive out, opened, the chore done, and the knife folded and back in my pocket in no time at all. But you might not want it to be your only blade in a national park because it IS tiny.

Tradeoffs and choices.
