Can anyone tell me about canadians

there's no fixing it like a broken bit.

Shanks can be repaired, stems and tenons can be replaced. Look at enough estate pipes you will see these type repairs.

they aren't meant to be clenched while you're doing something else.

Whether or not any pipe can be clenched is completely subjective.

I have a Ben Wade Canadian that’s 7 ¼ inch x 2.10 ounce, it’s completely comfortable between my teeth.

Even this pipe http://www.cigarasylum.com/vb/attach...8&d=1254545288 can be clenched, for a few minutes anyway, it tips the scale at 3 ounces.
