Wow. You can not go wrong with any of those choices. The Case is great because its not as ubiquitous as SAK but the loss factor comes into play.

Something must be said however that SAK keeps coming up and my wife has a small one for EDC, I have the Champ in regular rotation in my EDC.

I have given a lot of thought to my son's first knife. I have a ways to go, he's 5. I have narrowed it to a small SAK or an Old Timers knives. The Old Timers, (originals no longer made) are sold at Home Depot so they are easy to replace. The PAL is about $10 and a single blade. Its a nostalgic blade. Story's about its remarkable family past is usually highly exaggerated to create mystic. (wink wink)
