Do think it’s bit of a non-question, and a bit sad that it’s being asked. Not just by the OP, but in general. I’ve got a whole bunch of stuff around the house I could kill people with, but I’m not sure anything with a blade would be top of my list.
My wife brought me back a Sirupate Kukri from a work trip in Nepal. Slightly surprised that she wasn’t pulled up at customs. It’s very useful and versatile, you can cut meat, chop firewood, split kindling, strip branches, prune trees. Used it for all those things, and it’s a shame it’s not acceptable to have it along on a camping trip, when people wouldn’t blink at a hand axe.
