Historical Note:
Produced by Imperial Schrade under the Frontier label, these knives were popular during the 1970s and 1980s as dependable working tools. Their practical three-blade configuration made them a favorite among farmers, tradesmen, and outdoorsmen alike. The rosewood scales offered a step up in elegance from synthetic handles, making them as visually appealing as they were functional.

Collector’s Note:
This knife is a fine example of the mid-century American stockman—rugged, functional, and collectible. A worthy addition for anyone curating a vintage EDC or traditional knife collection.

All knives in this shop are vintage or pre-owned unless stated otherwise. While many are in excellent condition, they may show normal signs of age or handling such as scuffs, blemishes, or blade wear. I try to document condition as accurately as possible in both the description and photos. Feel free to reach out with any questions!
