Heading for Alaska. Taking the motorhome. Heard you couldn't take knives. Is this true? I have steak knives and butcher knives and butter knives, just your normal kitchen stuff. These things are in my motorhome. Does this mean if I'm at a campground in Canada and decide to barbeque steaks, I have to pull them apart with my hands? Heard you couldn't take knives across the boarder into Canada?
