flipe8,
Sorry to hear about the confiscation. Majority of Spydies almost never get deemed "flick" knives cause the pivot screw is usually tight enough.
I had a Benchmade confiscated by Can customs because it opened by gravity (when the appeals customs officer heard that it was a BM he said "yeah, we get/confiscate alot of those")
My advice would be to have the knife shipped back to the sender... friends who are customs officers say that if a knife fails the appeal, your name will be flagged as having imported a prohibited weapon- which may or may not lead to issues when you're crossing the border & dealing with Can customs. That being said, I'm sure there are many Canadian knife collectors/knuts who've had several knives seized in the past and probably havent had issues.
UPS and FedEx wont ship the knife. I believe Purolator will. So will DHL (but they're not as big). If you call and get an agent who wont ship it based on the fact that its a "prohib" weapon, call back a few hours later and try another agent. Shipping policy appears to differ between agents- mostly since they want your $$$.
You will have to fill out a few customs forms as well.
Also you may have to meet the courier agent at the Customs office to coordinate the entire transfer (at least I did). Customs agents seem to hate to deal with resends and tend not to sign anything (maybe cause they're allergic to paperwork) so dont expect any assistance from them when trying to get your knife sent back.
Hopefully your experience wont be as bad as mine. Good luck!
