The Wera Kraftform VDE Screwdriver Set 7 Piece is to my mind an excellent investment for the serious' sparky'.The screwdriver tips are well crafted Especially. Especially I am impressed with the Pozidriv screwdriver heads Which do not cam out after a few uses. More importantly, for the busy electrician They are comfortable even after repetitive use. The small terminal screwdriver has a good sturdy feel to it Allowing for tight clamping of terminal screws with no damage to the screw head. The small tester screwdriver is not of the same quality and is probably only put in as a filler. If you need a good selection of screwdrivers do not be guided by price alone. If you are starting out I suggest you did purchase thesis alongwith Knipex pliers, side cutters and Perhaps a Knipex wire stripper and you have the basis of a first class tool kit.
