Knipex for cutters, but I quite like the CK ones with the 2.5 & 1.5 slots, saves me the job of blowing them up to get the same result! Handy having the socket screw chopper on them too. Mind you, a good set of Knipex cut through screws like butter anyway. Used Draper screwdrivers for a while now, seem ok. Used to get a lifetime guarantee on CK screwdrivers, don't know if that's still the case. Use 'em, bugga 'em up, take them back to the wholesaler for a shiny new one!
