Foldup handle is 40% stronger than steel, and will not rust or corrode.
Handle is comfortable to hold, and does not conduct heat or cold.
Patented Bondhus® design allows selection of one blade at a time, without the need for annoying mechanisms to release a blade.
Blades have a positive stop at 270 degrees open. Flip & turn feature permits screw insertion or removal when working near an obstruction – without the need to continually remove and reinsert the tool into the screw head. Does not have ball end tips smaller than 5/32 and 4mm, since the handles could easily over-torque the blades and risk breakage. Blades are accessible from both sides for single blade selection without the "unstacking" of blades associated with metal Fold-ups. Made of Protanium® Steel with ProGuard™ dry finish. Hex sizes: 5/64" to 5/32" and 1.5mm - 5mm. Part # 12550.
