This artifact is a Modern Rampuri Chaku, featuring a 5-inch blade. It represents a specialized branch of North Indian folding mechanics, distinguished by its high-status all-metal construction. This specimen utilizes an external leaf-spring back-lock, documenting a design that prioritizes "Impact Certainty"—where the blade is physically prevented from closing during use by the constant tension of an external spring.
Core Components & Engineering
The Blade (5-inch Clip-Point Steel): A single-edged blade with a straight spine and an aggressive clip-point taper.
Geometry: The 5-inch length provides significant reach and leverage. The clip-point geometry lowers the tip relative to the spine, concentrating force into a microscopic surface area to maximize piercing efficiency.
Locking Tang: The tang features a deep, square-cut notch on the spine. When fully deployed, the lug of the back-spring snaps into this notch with significant force, creating a rigid mechanical bond.
The Hilt (Chased Brass All-Metal Assembly): Constructed entirely of heavy brass scales over a rigid steel frame.
Surface Ornamentation: The scales are heavily chased with a "Fish-Scale" motif. One side is embossed with "RAMPUR", and the reverse with "YAMEEN", documenting the regional lineage and maker.
Fish-Tail Pommel: The hilt terminates in a distinctive flared "fish-tail" pommel. Mechanically, this acts as a critical retention stop, ensuring the hand remains locked in position during high-pressure piercing maneuvers.
The Mechanism (External Spring-Loaded Back-Lock):
Operational Logic: A tempered steel leaf spring is pinned to the spine of the handle.
Unlocking Process: To close the blade, the user must pull back on the integrated brass tab to lift the spring's lug out of the tang notch.
Deployment: Deployment is manual. Once the blade reaches 180°, the high-tension spring automatically "slams" the lock into place.Made/Created
