Just want to say thanks so much for all the suggestions! I am reading through everything now and I have a lot of choices to research and think about. I'm learning and I'm sure will continue to learn- lots of fun being a mama to a boy.
At this point, I'm leaning towards a wooden or training sword- something he can swing around and play with and that won't break easily and also won't slice his pinky or finger off- man, all those stories you guys told are gonna make me a nervous wreck now. LOL. In general, he is not a careless kid.
He has a dirt bike (kid one obviously) and he took the time to go slow and learn it properly and he is a great rider now, always wears his helmet and doesn't take unnecessary risks. I believe he thought the dagger I bought him before was a throwing knife, because it looked similar to one and he was trying to copy what he saw on tv. (oops) His daddy was with him at the time, though. I know several have mentioned pocket knives but the folding kind of the kind that pops out (sorry- it will take me time to learn proper names- switch blade?) just makes me very nervous, which is why that wasn't my first go-to. I'll let his daddy make the decision for a first knife and the proper training instructions with how to handle it and I will most likely research the options for wooden or training type swords. Didn't even know about those. If he remains interested in knives and daggers as he gets older, I will go from there based on his age/maturity level. Maybe some throwing knives like several mentioned a little later on.
Glad to be on this forum with lots of helpful people. I am sure I will be back with more questions in the future.
Thanks so much, guys!
