I have a few bone arrowheads, they are nice gimmicks but I would not use them for hunting. I do have a few very crude and rough arrowheads made from pieces of chert and quartz that although not razor sharp, will kill a deer.
Now the idea of breaking the bone, that is a good idea. Like bamboo, break it and it will make a good weapon, scraper, spear point, or tool. But then so will a sharpened stick.
For quickness, break a bone and have a knife. Knapp a rock and chance cutting your finger, breaking the bone may just have a few valuable options.
I may need to try this.
I can tell ya one thang, if'n I'm skinning a hog or a deer, you can keep your metal knives as my favs are a coastal plains chert rock and a chunk of obsidian. Have to watch that obsidian though, will cut right through a thick hog hide with no problem, and maybe into your flesh.
