There is a lot of stuff to do in Colorado if you have the time and desire to drive all over. You all ready have the Spyderco thing figured out which is probably the only knife thing to do. Around Breckenridge? Other than Skiing? Bars and restaurants mostly..there is the Breckenridge brewery... there are places to rent snowmobiles or go on snowmobile guided tours way up in to the mountain, I always though that sounded fun. you can go on dog sled rides too.
We have lots of touristy crap like the Denver mint, museums, the zoo, a giant tropical aquariaum. There's a huge REI store with a climbing wall. Ever been to a Bass Pro Shop? I can spend all day there.
Red rocks is beautiful. We have casinos, steak house titty bars,brewery's,ghost towns, hot springs, cave of the winds, garden of the gods and all kinds of things that may or may not be your thing.
