You want to be really careful with the knife you get, because most customs agents are super picky. Almost anything can be confiscated. Make sure the knife isn't something that will swing open at the flick of your wrist, or is too large.
If you'd like, I can PM you the link to a Canadian site/dealer that has deals that are usually just as good as american site prices, if not better. Shipping will cost less and you have almost 0% chance of getting your knife confiscated at customs.
