my kids weren't interested in the 'kids' tools i got for them. they much prefere adult ones i got hand tools with shaped handle which they can use fine, then we were given a mini spade metal wooden handle would have been quite expensive i think, great fot kids and for some jobs i use it too. i personally would recommend getting a hoe. kids can use them easily with instant results digging is hard for them. and a watering can is essential one with a lid if you can get one
happy gardening
