I live in Canada and like A.F.P., I buy at Warriors and Wonders as well as SR Knives..
Knifeworks is awesome. Great customer service and fast shipping. Roger is awesome to work with. Once I needed some gifts for a group of people, fast. Called him and a couple of days had about a dozen pocket knives, all laser engraved with individual names, all in individual engraved wood presentation boxes. I always check there first.
Cutleryshoppe has massive inventory and is always the cheapest on Spyderco's (sometimes his prices are downright ridiculous) but he does sometimes sell stuff that's not in stock - and then tells you afterwards. I bought my GB from him and it took 3 months. That was seriously uncool.Cutleryshoppe.com is my go to place for Spydies. Jeff's prices are great with top notch service.
