Trench knives are prohibited due to the metal "Brass Knuckle" guard. If that guard was a "D" guard or made of a material other than metal, it would not be considered prohibited. It would be a fixed blade knife. No restrictions on importation of fixed blade knives.
Yes, you are correct. When I was using the term "trench knife" it was used within the context of this thread in which it was presumed that we were talking about a knife with a "Brass Knuckle" guard. Yes, there are trench knives that have "D" guards, which I did not include in the explanation because I didn't believe there was confusion about "D" guard variants (we were talking about "G10 knuckle dusters" and making a "Canada legal Mark I Trench Knife" or a "US 1918 mk1 L.F.& C trench knife", etc).
But I am glad that you brought it up because my omission may have caused some confusion. Thank you (not sarcasm).
Therefore, to classify a "brass knuckles knife" as prohibited:
(a) the handle must be a weapon; and
(b) that weapon must meet the definition of brass knuckles. It is not sufficient for the blade portion of the knife to be designed as a weapon
This is true. (But the Governor in Council could make new regulations to prescribe the knife as a "prohibited weapon" if, in the opinion of the Governor in Council, the knife is not reasonable for use in Canada for hunting or sporting purposes. Which is why I mentioned that if such a knife was created and
if it garnered a significant amount of negative attention, the proper authority could prescribe the knife to be a prohibited weapon in the future. (Section 117.15 of the Criminal Code of Canada)
