In an age before the digital screen, the slide rule was the ultimate tool of the analytical mind. The KLPZ pocket logarithmic ruler, manufactured in 1966, represents a pinnacle of Soviet analog engineering. Crafted from a blend of wood and celluloid, this instrument was designed not just for calculation, but for the tactile, disciplined process of engineering and drafting. Holding this piece today offers a rare glimpse into the mid-century scientific workflow, where logic was measured in precision scales and physical craftsmanship.
