Here are two pieces that are based in knives and weaponry, but aren't actually bladed.
First off is an archer's vambrace. It fits very well and is extremely comfortable, yet the surface is hard and waterproof and could most likely cause a light knife attack to be glanced. I could see myself donning this article and matching garb if any sort of apocalypse ever struck. My apologies for the quality of the photo.
Finally is this full sized cutting board-- oak and poplar. This was a collaboration of sorts with Charlee Ann, who did the great wood-burning.
