Fisher's New Space Pen Adds Ruler and Glass Breaker
Fisher's Measure Twice combines a Space Pen with short ruler markings and a hidden glass-breaker tip. A bolt-action control switches between the writing refill and the emergency tool, while the body is machined aluminum. It is priced at $62.10 and uses Fisher PR4 pressurized refills.
Fisher’s Measure Twice blends a pressurized Space Pen with two pocket tools. Its barrel carries 3.5-inch and 9-centimeter scales, laser-etched according to the manufacturer, while a bolt-action selector exposes either the writing refill or a hidden tungsten carbide tip.
The body is 6061 aluminum with an anodized finish, measuring 5.37 inches closed and about 0.39 inches wide. It ships with a black medium Fisher PR4 refill and accepts other PR-series refills. Fisher rates the sealed cartridge for inverted, underwater, and zero-gravity writing, with a stated -30°F to 250°F range and a claimed writing distance reaching 12,000 feet.
A combined pen, ruler, and concealed glass breaker may appeal to makers, technicians, outdoor note-takers, and everyday-carry users who value fewer separate items. Its higher price could limit adoption, so impact may stay niche rather than broad. If such multi-tool pens become common, they might influence how people prepare for small measurements or emergencies, but a dedicated rescue tool may remain preferable for vehicle safety.
