Share 'Home-made weapons'

So, I've been thinking, and I think i know of a couple of ways to make some awesome home-made weapons out of household objects. The most obvious to me is the Polearm, where you tape a kitchen knife to the end of a durable stick and use it as a long-range melee weapon. I haven't actually tried this yet, but i think it may work. Any other ideas, lets write them down! LOCK AND LOAD, BITCHES!!!
