While turning old tablelegs into baseballbats i though: "Why not make a baseballbat with a slingshot on the bottom?". Excellent weapon for the zombie apocalypse, short/medium ranged defence with close combat capabilities with the switch of two hands.
This is the prototype i came up with. I know it has tubbing that barely puts a dent in a pack of butter but it was my last theraband. Ordering new ones in springtime as rubber is no use in winter.
