Vintage Boker USA 1158 Pen Knife – Jigged Brown Bone – 2 Pen Blades – Circa Late 1960s–Early 1970s

This vintage Boker USA 1158 pen knife is a classic example of traditional American pocket cutlery from the late 1960s to early 1970s. Compact and refined, this knife follows the historic pen knife pattern—originally designed for fine, controlled cutting tasks.

The knife features two pen blades, both slim and tapered for precision work, housed in a compact frame ideal for everyday carry.

The handles are fitted with beautifully jigged brown bone, showing natural color variation from deep chocolate tones to lighter amber highlights. The irregular jigging and subtle edge lightening from traditional hafting give the knife a warm, authentic character that only bone develops over time.

Stamped “Boker U.S.A.,” this piece reflects a period when Boker’s American production still emphasized traditional materials and construction methods.
