Just pulled it out from my giant box'o'knives, I'll be darned if the blade isn't exactly 3.5", so legal carry. The other 3.5" knife I was thinking of buying would be a better blade shape to double as a trail cooking knife, but it's nice to know I have this one for now, not that I am thinking of biking in the area of the attack, so not urgent.

It's too bad that having a long bayonet on the bike would be way outside of legal code, because I saw a study that said, for someone not extremely well trained with an edged weapon, especially a heavy swinging one, the most effective and simplest defensive weapon is a poking stick (non-thrown spear), which is why soldiers are taught to use a bayonet on the end of a rifle, it's a much better standoff weapon than trying to competently use other large edged weapons. So that on the end of a solid staff would be ideal I think.
