I had never really considered tactical canes, but that is because I never thought I'd need one. Upon reflection, canes are capable of serious tactical impact, and that's without the addons you're bringing to the table. A question only slightly tongue in cheek: is there an option for a pickatinny rail?
I'm glad to see your steel trap mind back at work, if slightly padded by the morphine. Keep on keeping on.
Thanks!
