A 1948 advertisement for a Weller soldering gun. Pistol-grip electrically-heated soldering tools had been used since the 1920s. In 1941 Carl E. Weller invented and later obtained U.S. patent 2,405,866 [1] for a transformer-based soldering tool which heated and cooled rapidly, [2] essentially as described in this article.
The greater the hone angle of the wheel, the sharper the angle of the V and the thicker the piece of glass it is designed to cut. The hone angle on most hand-held glass cutters is 120° to 140°, though wheels are made as near-flat as 154° or even 160° [180° would be flat like a roller] for cutting glass as thick as 0.5 inches (13 mm).

A scoring knife or scoring tool is a handheld tool used to cut a groove in a sheet of material. The cutting edge of the knife is often made of hard material such tungsten carbide. The scoring knife is drawn across the material in a straight line (with the help of a straightedge), creating a scratch or score in the sheet. The material can then ...
Front cover – The M16A1 Rifle – Operation and Preventive Maintenance by Will Eisner, issued to American soldiers in the Vietnam War. An inadequately maintained firearm will often accumulate excessive fouling and dirt within the barrel and receiver, which not only can clog up the rifling and decrease the firearm's accuracy and precision, but can also interfere with the proper operation of ...
Linear cutting tools include tool bits (single-point cutting tools) and broaches. Rotary cutting tools include drill bits, countersinks and counterbores, taps and dies, reamers, and cold saw blades. Other cutting tools, such as bandsaw blades, hacksaw blades, and fly cutters, combine aspects of linear and rotary motion. The majority of these ...
