Here's what I took to college in 1987 ...
1) Slippie: Old Timer 33OT jack, and a Victorinox Explorer.
2) SD-oriented blade: Schrade LB7
3) Folding tank: See above
4) Knife lovers knife:

I loved them
all.
Here's what I'd take to college If I could do it over, knowing what I know now ...
1) Slippie: Victorinox Ramber.
2) SD-oriented blade: None (just good old common sense).
3) Folding tank: One of the lower-end Leathermans (maybe a Kick).
4) Knife lovers knife: Case peanut, or maybe Swayback Jack.
Get what you realistically need, and then don't spend any more money on knives while you're in college. Save every spare penny and then spend it wisely on chicks and beer and cool road-trips. You'll have the rest of your life to buy crap. Study hard (not joking here), and have a ball!

OOPS. I just read further down on page 1 that you're a 26 year old army veteran with a fiancee. So, scratch the beer and chicks recommendation.

But it seems you have an even bigger reason to be frugal. Hey, it's your money and I certainly don't know your financial situation. But I can tell you, as a 44-year-old who has been married going on 12 years, try to head into your marriage with more dollars than toys. Later on, when you two are settled, you can guy whatever floats your boat. Lastly, thanks for your service in the army! :thumbup:
