Teddy is left handed.
See the bandage?
Yep. that is his left hand. So, how do you cut your dominant hand while using a multitool to cut cardboard, you ask? Well....if the place that needs cutting is more convenient to your right hand.....
No, he didn't need stitches. Nor did he need a tetnus shot. Just serious cleaning and steri strips, to hold down the chunk of finger he sliced off (I expected them to glue it, but they didn't).
Patience? Nope, none left. All used up.
