About
What it is, and why it matters
The Arizmendi Teuf-Teuf is a Spanish .25 ACP blowback semi-automatic vest-pocket pistol produced under one of the trade names used by Francisco Arizmendi y Goenaga of Eibar. Like most Eibar-made pocket pistols of the era, it is a close copy of John Browning's Colt/FN Model 1908 Vest Pocket design, featuring a striker-fired action, a single-stack detachable magazine, a rear-mounted thumb safety and a magazine disconnect. Marketed for civilian self-defence and concealed carry between the World Wars, it was one of countless small-caliber pistols that flowed out of the Basque gunmaking town before production was halted around the Spanish Civil War.
During the early 20th century the Basque town of Eibar produced a flood of inexpensive 6.35mm pocket pistols sold under dozens of fanciful trade names. The onomatopoeic "Teuf-Teuf" - French slang echoing the sputter of an early automobile engine - was one such marketing label, attaching a touch of modern, mechanical glamour to an otherwise utilitarian self-defence pistol.
"Teuf-Teuf" was a brand/trade name applied to inexpensive Eibar vest-pocket pistols; like many Spanish 6.35mm pistols of the period, individual specimens vary slightly. Figures here reflect the typical Colt/FN 1908 Vest Pocket-pattern .25 it was modeled on.
