Table knives are great for prying Legos.....
Had my first knife at 4, (46 years ago). My daughter got hers at 6, at 13 got a dagger (girl's best friend) and has graduated to swords.
Getting cut badly is just part of the process.... prying with a sharp blade will assure this happens sooner. Especially with a non-locking folder.
Eeeeew!
'Ironballs', I am sorry, but having a child anywhere near a moving lawn mower is far worse than giving them a knife. I used to do the same with my l'il cutie till I was shown the danger. It is great to share things. Funerals and hospital visits are not good to share.... No matter how well manicured, the chance of an object being flung is far too great, especially in a yard where kids play with, and leave, all kinds of things in thick grass. Years ago, in my 'town life', my push mower stuck the end of a piece of twisted wire coat hanger through a wooden lattice.
Please think about it, Bud. I want you enjoy your daughter's teen years as much as I am with mine......
Today, my 'mown area' is kinda rough and my 'lawn'tractor frequently fires golfball-size, and up, chunks of Texas Hill Country into the neighboring states. Nobody comes out until the blades are disengaged.
