Overview

A classic American folding pocket knife featuring a two-blade 'jack' configuration with a clip point main blade and a smaller pen blade. It utilizes Imperial's patented 'shell handle' construction, where thin celluloid or plastic covers are wrapped over a stamped steel frame to mimic more expensive solid bone or stag.

Story

Born in the 1940s, this knife was the 'everyman's' tool, designed to be affordable yet reliable during the post-war boom. Its bright red handle and oval shield made it a staple in hardware stores across America for decades. It’s a survivor of the era when a pocket knife was as essential as a wallet.

Maker / Origin

The Imperial Knife Company was founded in 1916 by Felix and Michael Mirando. They revolutionized the industry by inventing the 'shell' handle process, which allowed them to mass-produce durable, attractive knives at a fraction of the cost of traditional cutlers, eventually becoming one of the largest knife makers in the world.

Condition & Value

The blades show significant sharpening wear and a heavy carbon patina, which is typical for a used tool of this age. The red handle covers appear intact without the common 'outgassing' or shrinking often seen in old celluloid.

Market Analysis

Comparable demand stays strongest where maker, originality, and venue confidence line up. Broader examples still trade, but the range tightens quickly when provenance, condition, or selling lane fit is missing.

Value Drivers

  • Strong maker attribution with credible period details
  • Better-than-average condition for the category
  • Broader demand rises when presentation and finish feel intact

Concerns

  • Decorative-only demand limits the ceiling
  • Surface wear or missing provenance can compress the range fast
  • Regional sale lanes often underperform specialist venues
