I got my daisy at age 5. I got a single blade vic sometime shortly after that. I lost it, then found it several years later under the large live oak tree in the back yard, up in which I spent most of my time. It was rusted shut from the elements and by that time I had another knife so I think that first one found the trash. By age 10 I was wandering our property unsupervised with a ruger 10/22. I still have the bb gun some 25 years later- it still shoots as well as any daisy ever did- and my dad still uses the 10/22 for armadillo ellimination duty. I never noticed you could see the bb in the air until much later in life. Many a grackle and sparrow fell victim to that bb gun. The squirrel population has yet to rebound on our property from my days with that .22. I was 12 or 13 when I started deer hunting with my dad, and I remember my mom saying that she would trust me with a firearm over most of the 18+ year olds that she knew. It is not about the age of the child, but the maturity.
My three year old knows that knives are sharp, and that they can cut, and he'll get his first knife when he could have a use for one. He has expressed interest in going deer hunting with me, although I don't know that he really understands what that means. Over the holidays, I hope to teach him about it when we are back at my parents place in Texas. He'll start just like I did, sitting quietly next to dad expectantly waiting the arrival of a deer- but hopefully his dad will be more understanding of the extrememly boring nature of blind hunting, and how a child can get cold sitting still even when it is not terribly cold out.
