Welcome to the mix Lad,
You just asked the "$64,000" question. I'm sure there will be a wide spectrum of answers.
Since you asked the question, I must assume that you don't have a great deal of experience in the world of knives. I also assume that your price is in Canadian. Since it isn't high I'm also assuming that you are on a fairly tight budget.
That said, I have a few recomendations: 1) A standard Buck #110 Folding Hunter. These are priced low enough that you can try one to see how it feels to you to carry around. It is common enough that even the RCMP boys usually don't give it a second look. It holds an edge fairly well, but is easy to sharpen, an important point for a newby. There is nothing more frustrating than trying to sharpen a knife for the first time and most of the new wonder steels don't help any. Then it weighs more than most of the latest High Tech offerings, you may like it, you may not, but it doesn't cost alot. Nothing like spending big bucks only to find that the knife that was soooo great in the store has become the blade from hell.
Another knife that might interest you would be a Spyderco Endura, again pretty good steel, it's much lighter than the Buck and has a pocket clip, which you may or may not like. This also applies to the Cold Steel Brand of folders. Now I say this with the Idea in mind that you could buy one of each for the collective price of $150 C. Each is enough different that you can get a feel for some of the style differences and beable to refine your prefferences, before moving upscale in knives. I listed only sterdy lockbacks because "I" think they are safer for someone just getting into the knife world and ther is less chance of biting yourself, that using a linerlock when you're not even acustomed to using a folding knife.
Now I've made some gross assumptions here and if I'm wrong at any point, I'm sorry, but you didn't leave much information to work with.
Luck to ya,
Dan
