This is on a good sized antler base and fits in the hand nicely. I gave it to the guy who gave me some antlers.
This next one is maybe not as big as it looks when I cropped the photo. It saves one the trouble of hafting etc. It is called a Kerrville knife. The whiteish stuff is the outside of a chert cobble and fits into your palm for the handle. Makes you want to go butcher a mastadon or something.
