I would be very cautious buying this product, Amazon showed it to me based off of other activity on their site as a "suggested product" and my concerns prompted me to write this review.
Canada has specific prohibitions against "push daggers" contained in regulations and punishable under the criminal code, just as butterfly knives are illegal along with knuckle dusters and other items.
The look of the knife implies to me that it may be construed as a push dagger. I would be *very* cautious as possession of a prohibited weapon can carry extensive penalties in Canada.
Do your own research, make your own decisions, but consider yourself forewarned.
