Hey there, don't panic! I'm sure there are plenty of people here willing to help you out.
It WOULD help if you gave us some details. For example, the most important: what's your budget? I mean, there are so many quality knives out there...for a Chris Reeve Sebenza going for $300+, to several others from fine companies like Spyderco, Benchmade, Microtech, Buck, that go for lower yet have great quality. If you give us a price range, we could help you better.
Also, what length do you envision? Might be a large knife, like something around a 4" blade, or smaller, which would be around 2", or of course mid-size around 3"...
Also, is your boyfriend a knife-nut?(e.g. spends a lot or most of his salary in knives). If he possesses many, then you have to be a little more careful and discriminating in what you get him.
Hey, I'm sure there are plenty of people which could provide you with links and pics, but we really need more information so we can help you make a good purchasing decision.
As for me, without knowing anything about your preferences or your boyfriend's I vote for my favorite, the Spyderco Native. You can get this knife at an extremely reasonable price ($43 at discountknives.com, the knife will arrive in 3-7 days), and is a mid-size (3" blade), plus it's a great all-around knife.
Good luck on your purchase. I'm sure your boyfriend (BF???) will be very happy with his gift.
Just hope he doesn't become a knife-nut like us, because he will end up spending more money on knives than on anything else! (including gf's!!!)
