Some knives boast innovations that add to the practicality, others showcase special features that add to the aesthetic, and then there’s the Imperial Trick Knife.
The Trick Knife is a single bladed non locking folding knife that was made with a rather unique feature. Within the blade well a space was cut in the liners that housed a small free moving bar. That bar moves up and down in its housing due to gravity as the knife is turned. Why? It gives the knife a “trick”; the blade can only be opened when the knife is upside down and can only be closed when the knife is upright.
What is the purpose of this feature? Well, as the name suggests, it really only serves as a fun trick to challenge your friends. In fact, some original advertising even claimed that only the most calm tempered could open it without frustration the first time. There’s not much practical use of a knife locking closed and not open. That said, if you want to “secure” your knife against someone opening it without your leave (like, in my case, if you have a small child around) it could be a useful feature… at least until they figure out the trick.
Despite its endearing quirkiness, the trick mechanism seems to have been seen as pure novelty by the manufacturer. The blade tang is stamped with several patent numbers. The tang numbers correspond to patents for the construction of the handle, but I could find no patents related to the locking mechanism online. Also, these trick knives were often given away by companies as advertising knives with their logo etched on the handles, or sold cheaply with TV character graphics on the handles.
the bottom line of the tang stamp on the Trick Knife
Despite the fact that the trick mechanism isn’t overly practical and the trick knife was sold as a novelty, it’s a unique and interesting piece of cutlery history. It hearkens back to a golden age of the knife industry when there was widespread innovation, just like there is today. Just as with those of today, not all cutlery innovations of the past took hold. Even still, the Imperial Trick Knife oozes a certain endearing nostalgia that can’t be denied.
Thank you to Jerram for loaning this awesome piece of cutlery history, and congratulations on owning such a great heirloom!
