I know there are many cultures around the world, Inuits, etc. who would answer this question by saying, what the hell are you waiting for?
However, they are not married to my wife who takes a more cautious approach to these things.
I have an 8 year old son who has grown up watching me use a variety of knives for a variety of tasks, from EDC, to food prep, to fishing/hunting to basic bushcraft. He has grown up viewing knives as tools and not weapons. He respects them, sees how I care for mine and I have spoken with him many times about the damage they can do if mishandled or used when not concentrating.
I have let him handle mine under my watch and my wife and I let him handle a knife under our supervision in the kitchen, which he loves to do. As a lover of the outdoors he enjoys whittling. I think it started during summers when I would let him clean branches to use as a skewer for roasting marshmallows.
I would like to get him his first knife, that he can use for basic bushcraft and was looking at the Mora Scout 39 Safe https://morakniv.se/.../scout-39-safe/
I was just curious if anyone had any familiarity with it.
