The multitool argument gets better when you fully realize what havoc a three year old can wreck if you take your eyes off of them for two New York seconds. All three of my kids and two out of three of my grandkids created afor mentioned havoc in just a few minutes. When they discover they can take out or dismantle things, it's amazing how much you'll need a screw driver or pliers. A mulitool and clean up stuff is mandatory. Especially when your kid realizes if he squeezes his cardboard sip up juice container right in the middle, it shoots a stream of liquid straight up. This is amazingly funny to them. Paper towels/wipes needed. Knife, maybe not so much. But when they knock over that end table and the lamp hits the floor but doesn't break, you'll need that little multitool to reassemble the lamp head to the main body where it stripped out. The small screw driver to loosen up the set screw, and the pliers to shove the base of the lamp head back down into the lamp body, the tighten up the set screw good and tight.
Kids cause chaos, you need tools!
