Good job, Dad.
I was telling someone the other day, I remember getting my first pocket knife around 7 years old and widdled wood with it, cleaned fish, and took it camping regularly. We did a lot of camping when I was a kid. Good times.
When not is use, I just put it in the kitchen drawer at home with the rest of the utensils. I guess times have changed a lot even in my lifetime, it was then and still is just a tool. Was in the Cub Scouts and Boy Scouts, made Eagle Scout, and recall taking the class for permission to carry a knife (we were given a card, right???) and thought it was just a lot of common sense stuff; but I guess I took for granted at the time that my dad spent the time to teach me how to use one properly and the responsibility that went a long with it.
Very happy to hear of the memories for you and your son.
