A citation-first field guide to the makers of American pocket knives, before the war
What each brand offered, over time — patterns, handle materials, prices, and above all how to date a knife by its tang stamp — with every fact tied to a primary source. Built the way a definitive reference should be: the document that proves a claim is never more than a click away.
The rule throughout: a primary source establishes a fact; secondary works are only leads. Every page carries its sources and a confidence flag, so you always know what proves what. The focus is American cutlery made before the Second World War.
