Nations Attic 2026 Diving Into History + More
Lot 113:
Description
Originating from the 1917 AJ Morse catalog, this spring-lock mechanism knife is an extraordinary find and arguably one of the rarest American diving knives ever produced. While the catalog featured three distinct styles, this specific design remains virtually unknown to modern collectors. At the time, it was marketed for its superior accessibility, advertised as being "much more easily withdrawn" than the cumbersome, traditional screw-pattern sheaths. Despite this clear functional advantage, the knife never saw widespread adoption. This scarcity is likely due to the high production costs of its intricate handle or a lack of official approval from the US Navy, which would have limited its use to a small circle of commercial divers.This particular specimen has survived in very good condition, showcasing a simple yet effective mechanical design. The knife is operated by a trigger button located on the edge of the flat brass handle; when pressed, the spring-loaded mechanism disengages an internal hook, allowing the blade to slide freely from its flat brass sheath. Two flathead screws on the handle secure the internal trigger system, a hallmark of this elusive model. Interestingly, its greatest strength—speed—may have been its downfall; the efficiency of the lock likely led divers to inadvertently lose blades by failing to ensure they were fully engaged. As evidenced by the accompanying photographs, this specimen is in good condition, with its integral trigger mechanism remaining fully functional. While the knife and sheath lack manufacturer stamps or hallmarks, their identification is anchored in the 1917 AJ Morse catalog—the sole historical record of this specialized design. Substantial in hand, the piece weighs a collective 2 pounds 14 ounces, with a handle geometry that immediately distinguishes it from more common diving tools of the era.The factory-capped brass sheath is marked with a small stamped “2” and displays a rich patina of authentic wear, including the characteristic dings and marks around the throat that speak to a lifetime of original use. The blade similarly exhibits an honest age-related patina and features a unique, subtle flare toward the tip. While we have previously encountered the flat-sheath iteration of this model, this round-sheath variant is an extraordinary rarity that we have never before handled at auction. For the serious collector, this represents a premier opportunity to acquire a virtually undocumented United States made dive knife.All items will be shipped with a signature required upon delivery and full insurance either via FedEx or the USPS Priority Mail.
