Is this what you are talking about?
Not to sound like a party pooper but check your local laws on double edged blades, I know they are illegal here ! <img src="/ubbthreads/images/graemlins/frown.gif" alt="" />
I am positive that double edged blades are legal for purchase and carry in Canada, Pit. As long as it is only a "tool", and not for self defence (stupid law), or concealed, it's all good. I have a pair of these on order. I will have a very nice box cutter that only needs to be sharpened half as much <img src="/ubbthreads/images/graemlins/wink.gif" alt="" />
