Between 1942 and 1945, Zippo stopped making the chrome lighters it had been producing since 1933 and switched entirely to steel. Chrome was a war material. The result was a lighter that looks and feels fundamentally different from every Zippo made before or since — and carries a story that no post-war reproduction can replicate.
The Wartime Decision
When the United States entered World War II in December 1941, Zippo's founder George Blaisdell made a decision that would define the company's collector legacy. He converted the entire Bradford, Pennsylvania factory to military production and sold the entire output to the US military and PX stores. Civilian production stopped completely.
Because chrome was restricted for military hardware, Zippo switched to a low-carbon steel case with a black crinkle paint finish — the same paint used on military equipment. These aren't chrome lighters with a different paint job. The metal is different. The weight is different. And when you pick one up, you can feel it.
Identifying a Genuine Wartime Zippo
The Steel Case
The most fundamental test is magnetism. Chrome and brass are not magnetic. Wartime Zippo steel cases are. A magnet held to the case of a genuine wartime Zippo will attract. This single test eliminates most fakes immediately — reproduction wartime Zippos are usually made from chrome-plated brass and will not attract a magnet.
Note: the inside of the lighter (the insert) may have been replaced over the decades. Test the outer case specifically, not the insert.
The Black Crinkle Finish
Genuine wartime Zippos have a distinctive crinkle texture to the paint — small, consistent peaks and valleys across the surface, similar to the texture on vintage military equipment. This finish was functional: it reduced glare and improved grip.
The finish on genuine examples has a specific quality to it — slightly rough under the fingertip, with consistent crinkle depth. Reproductions often have the right color but the wrong texture: either too smooth or with an inconsistent, applied-looking crinkle.
Wear is expected and acceptable. Genuine wartime Zippos that were carried in the field will show paint wear at the corners and edges, often revealing the steel beneath. This is correct and does not devalue the piece — in fact, field-worn examples with provenance (engraving, initials, unit markings) can be worth significantly more than pristine uncarried examples.
The Bottom Stamp
Wartime Zippos carry the PAT. 2032695 stamp — the first patent number, granted in 1937 and used through 1950. Any Zippo with this stamp and steel construction dates to 1942–1945. If the stamp says 2517191 (post-1950) but the case appears to be wartime steel, something is wrong — either the stamp or the case has been altered or substituted.
The Insert
Wartime Zippo inserts are also steel — not chrome. Look at the insert when it's out of the case. Genuine wartime inserts are a dull steel grey, not chrome-bright. The flint wheel on wartime examples is also steel, slightly rougher in appearance than post-war variants.
Many wartime Zippos have had their inserts replaced over the decades — they wear out. A wartime case with a post-war insert is still a wartime case and valued accordingly, but it's worth noting the discrepancy.
What Wartime Engraving Means
Many wartime Zippos were personalized by their owners or given as gifts. Engraving — initials, unit designations, dates, names, locations — adds significant collector value if it's genuine and consistent with the period.
Look for: hand-engraved lettering (inconsistent depth and spacing, as a person would make), unit designations consistent with known WWII formations, dates in the 1942–1945 range, and theater-specific references (Pacific, European, North African campaigns).
Professional machine engraving that is too consistent, or post-war military unit designations on a wartime case, suggests the engraving was added later. This doesn't necessarily mean fraud — people added engravings to beloved old lighters for decades — but it affects the collectibility and should be reflected in the price.
Variants and Values
Not all wartime Zippos are equal:
- Standard black crinkle, no engraving, working condition: $150–$350
- Standard with original period engraving (initials, date): $250–$500
- Unit-marked or theater-specific engraving with provenance: $400–$1,000+
- Nurse's Zippo or other non-combat personnel: $200–$400 (rarer than combat examples)
- Presentation examples (given as awards or gifts) with documentation: $500–$2,000+
Condition matters, but wartime Zippos are field objects. A pristine example with no wear is actually slightly unusual — most of these lighters were carried. Honest field wear does not significantly depress value for genuine examples.
The Korean and Vietnam Connection
Zippo also produced lighters during the Korean War (1950–1953) and Vietnam War era. These are not wartime steel-case Zippos — they're standard chrome production — but Vietnam-era lighters (identifiable by the 1960s–70s bottom stamps) with theater engravings are their own category of collectible.
Vietnam-engraved Zippos are particularly interesting because soldiers did their own engraving in-country — often crude, deeply personal, and sometimes dark. These are documented in collector literature and are a distinct sub-category. See our full Vietnam Zippo guide for more detail.
A Note on Reproductions
Zippo itself produces authorized reproductions of wartime lighters — the "1941 Replica" series, for example. These are clearly marked as reproductions on the base and are not intended to deceive. They're made from chrome brass, not steel, and will not attract a magnet. They're collectable in their own right but worth a fraction of genuine wartime examples.
The fakes to watch for are deceptively aged chrome lighters with paint applied to simulate a wartime finish. The magnet test catches these immediately.
