Vintage Keen Kutter K729 Pen Knife – Circa 1945–1955 – Yellow Swirl Celluloid Handles – Two Blade USA Pocket Knife w/ Anvil Tang Stamp

This vintage Keen Kutter K729 pen knife is a charming mid-century relic, featuring bright yellow swirl celluloid handles and two versatile blades. The standout detail? The tang proudly bears the Keen Kutter name inside an anvil logo, a classic mark tied to the golden era of American hardware branding.

Maker: Keen Kutter (contracted production, likely Camillus or Imperial)
Pattern Number: K729 (stamped on reverse of main blade)
Blades: 2 – spear point and pen blade
Handle Material: Yellow swirl celluloid
Bolsters: Nickel silver
Liners: Brass
Closed Length: Approx. 3 1/4"
Key Ring: Attached loop for easy carry or display

Condition:
Both blades show surface wear and a light patina consistent with age but still open and close with a smooth action. The colorful celluloid handles are intact and bright, showing only minor handling marks—no cracks or major flaws. Nickel silver bolsters show typical tarnish, adding vintage character. Please see photos for full details.

Historical Note:
This knife dates to approximately 1945–1955, a period when the Keen Kutter brand was managed by Shapleigh Hardware Company following their full takeover from E.C. Simmons. During this time, Shapleigh contracted knife production to firms like Camillus and Imperial, ensuring that Keen Kutter knives remained affordable and well-made for American consumers.
The anvil-logo tang stamp represents a beloved period when hardware stores were the heart of American communities and products were built for life.

Collector’s Note:
While not extremely rare, this specific combination—yellow swirl celluloid handles, anvil tang stamp, and mid-century production—makes this a less common and highly display-worthy piece. A great addition to any vintage pocket knife collection or a meaningful EDC choice for someone who appreciates American craftsmanship.
