Description: Screwdrivers and wrenches are now for sale at handtoolrescue.com The largest in antique screwdrivery, this screwdriver is based off an 1904 patent by William Ward, but with several modern improvements. These are sometimes referred to as "Perfect Handle" screwdriver due to the name H.D. Smith Co. used for there line of screwdrivers will a similar style. Each screwdriver is made from 1144 steel, is 10.5in/26.6cm long, and weighs 1lb/454g. The square shaft is 5/8in/1.5cm thick. The blade is 1in/2.5cm wide and 1/8in/0.3cm thick. Blade is hardened to 52 Rc. The blade on the screwdriver is now a consistent width, unlike the tapered design of most modern screwdrivers, to assist in removal of countersunk screws. The blade tip also has a hollow-ground design ensuring 1/10in/2.5mm of the tip is parallel, allowing for maximum engagement with the fastener. The handle has been re-positioned so that it is perpendicular with the blade to allow for increased strength when using the screwdriver for prying. The handle has also been designed to encapsulate the handle scales, so that even without brass pins, the scales will stay in place. The square shaft allows you to use wrenches to increase the amount of torque you can apply to the fastener if they are really stuck! This was a major design and production undertaking that took about 2 years of prototyping to finalize. I excited to share this with everyone! Big thank you to @yxecnc as well!
