The American Pocket Knife is a historical reference compiled by PhotoOpAI, Inc. for education and research. Please read the following before relying on anything you find here.
The Site's entries are drawn from period documents — manufacturer and wholesale catalogs, price lists, trade journals, and patent and trademark records — together with clearly-marked secondary sources. These originals are the best evidence we have, but they are incomplete, occasionally contradictory, and were written to sell knives, not to satisfy modern historians. Where old catalogs were digitized by optical-character recognition, transcription errors are possible. We verify and flag our confidence in each fact, but we cannot warrant that every date, name, or figure is correct.
Prices shown are the wholesale or retail figures as published in their period sources — often quoted per dozen to the trade. They illustrate what a knife cost in its own day. They are not appraisals and bear no relationship to what any knife is worth today.
The tang-stamp and marking keys on this Site summarize the best available understanding of how each maker marked its knives over time. Stamps were reused and transitional; dies wore and were replaced; contract cutlers stamped other firms' brands; and outright counterfeits and look-alike imports existed. Treat a dating range as an informed estimate, corroborated against other evidence — not a certificate.
Brand, product, and company names on this Site — including Case, Tested XX, Remington, Winchester, Ka-Bar, Keen Kutter, Cattaraugus, Camillus, Schrade, and others — are the trademarks or registered trademarks of their respective owners, some of which remain active businesses. They are used here only to identify and describe the historical knives they name. This Site is independent and is not affiliated with, endorsed by, or sponsored by any manufacturer or current rights-holder.
Some source documents reflect the commercial language and attitudes of their era, including terms and imagery that are outdated or offensive today. We reproduce or cite such material only for historical accuracy; its inclusion is not an endorsement.
The Site is provided "as is," without warranties of any kind, and your use of it is subject to our Terms & Conditions, including the limitations of liability set out there.
