This is an area of child-rearing where you don't just decide you're going to jump in, one day.
Tools are serious stuff.....and the uninitiated can do an awful lot of harm with the most benign of them.
I started my eldest son on the bulldozer when he was 6.....because he was ready.
I bought my second son a good set of tools when he was 9..... because he was ready.
If you are a parent who works with their hands...and tools...on a regular basis, you're going to have much greater hope of success teaching your young.
Handing someone tools while they work, and watching the processes unfold from a few feet away, is priceless education for an aspiring young mechanic/plumber/millwright, etc.
Use great discretion and teach them to respect those tools before they ever have access to them.
Oh....and for the very young.... they do make the awesomest little two gallon plastic chore buckets with steel wire bail...
