I hope they have learned from Mom :-)
yes a set of screwdrivers + a set of torxs-cerwdrivers , pliers , a handsaw .. yes a handsaw .. you never know
square and a ruler , don´t forget a pensel :-) , hammers one small pen and a medium claw, level , Voltmeter
or testpen , the smart electric thing that can find electric wires and plumming/watertubes in the walls
okay the wishlist is long you know all about that yourself :-)
but a deasent handdrill is usualy the first powertool every DIY got and today I presume its a 12-14V
screw/boreing drill that becomes most handy and a set of screwbits and drillbits to it remeber the note to them about there is different drillbits for different materials like brickwalls ,wood , metal ,
as the toolfreaks most of are its hard to ristrict ourself … LOL
but I´m sure you will make a very fine toolbox to them
good luck with it
