My Weblo scout just left for camp. I tried to follow the basics and double ziplocked the following kit from things at home before he left. Anything he has, he knows how to use.

*Camillus Boy Scout Lockback Folding Hunter - he does know how to use it safely. Has an official sheath (cordura) and I made him a functional, adjustable, bright orange lanyard tied with a Reeve coil. In my "everybody-has-one" opinion, SAKs and non-lockers are dangerous for kids (and some grown-ups).
*Matches in orange waterproof container
*PJ-soaked cotton balls in orange waterproof container.
*Large garbage bag wrapped compact with rubberband
*Large bright red bandanna (didn't have orange)
*25 ft of 15 lb. test line w/ 5 hooks and 5 sinkers - in a pill dose size ziplock - kids should already know how to fish with this
*Candle stub wrapped in aluminum foil - pill size ziplock
*Bandaids, adhesive sutures, anitseptic wipes in pill size ziplock
*Silva map compass and I told him to ask (demand) for a map.
*Pealess, orange safety whistle w/ lanyard
*Signal mirror
*P-52 can opener on keyring
*Canteen full of water
*Space blanket in a ziplock
*AA flashlight in ziplock
*4 large safety pins in pill zip lock
*2 large rubber bands
*10 ft of mason string
* 2 - 3 feet of 1 inch wide duct tape wrapped on tiny rod
* fresnel lens

He will carry it all on a hike. Whistle around his neck. Knife on belt. Everything except canteen into a waist pack.
