Rampuri, Knife, FoldersDescription
This artifact is a Modern Rampuri Chaku, featuring a substantial 6-inch blade. It represents the heavy-duty tier of North Indian mechanical folders. This specimen utilizes a high-tension external spring-loaded back-lock, documenting a design that prioritizes "Impact Certainty"—where the blade is physically prevented from closing during use by the constant vertical tension of an external leaf spring.
Core Components & Engineering
The Blade (6-inch Clip-Point Steel): A single-edged blade with a straight spine and an aggressive clip-point distal taper.
Geometry: The 6-inch length provides significant reach and mechanical leverage. The clip-point geometry lowers the tip relative to the spine, concentrating the force of a strike into a microscopic surface area.
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 (Hybrid Brass and Hardwood Assembly): Constructed with a steel internal frame, reinforced by heavy brass bolsters and dark hardwood scales.
Architecture: Features polished brass bolsters at both the pivot and the pommel. The bolster at the pivot is hand-stamped with "RAMPUR", documenting the tool's regional lineage.
Pommel Detail: 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 (the "lever") 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, converting the folder into a structurally stable fixed-blade.Made/Created
