I have a bad hip and I was leaning in with the grinder. My hip cramped up and I tried to catch myself with one hand so I didn't faceplant into the spiky bits. The grinder caught in one of the body channels and shot over and got my hand.
Oh well, it will heal. I cleaned it and bandaged it up with gauze and duct tape. When my daughter got home, she made me stop and let her clean and bandage it again because she got her first aid certification recently and told me I could not have done it more wrong if I tried.
I was amused, but let her do it. It was fine, but good practice for her.
