Pistol Grip Knife Handle with Index Finger Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional knives with straight blades and inline handles do not allow for a natural and comfortable grip similar to firearms, making it difficult for users trained with pistols to effectively apply their muscle memory and techniques to edged weapons in close quarters combat.
Innovation Solution
A knife design with a fixed blade and a pistol grip-like handle, featuring an index finger retention hole and contrasting forward sighting area, simulating the handling and feel of a handgun to facilitate comfortable forward thrusting and aiming, allowing for the translation of pistol drawing and pointing techniques to edged weapon use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional knife with an inline handle is used, then the blade can be pointed up or down in a natural stance, but the user cannot apply muscle memory and techniques from firearm training to edged weapon use
Solution Approach 1:
The handle is designed with an asymmetric pistol grip configuration where the grip axis is angled at approximately 90 degrees to the blade centerline, rather than being inline with the blade. This asymmetric arrangement allows the user's hand to be positioned perpendicular to the blade, enabling natural pistol-like drawing and thrusting motions while maintaining comfortable wrist alignment, thus resolving the contradiction between adapting to firearm techniques and maintaining operational comfort
2Adaptability or versatility
If a pistol grip-like handle is used, then the user can apply muscle memory from firearm training, but the handle structure becomes more complex compared to traditional inline handles
Solution Approach 1:
The pistol grip handle, blade tang, and finger retention features are merged into a single integrated structure. The handle is formed as one piece with the blade tang, eliminating the need for separate handle components, fasteners, or attachment mechanisms. This integration achieves the complex pistol grip configuration while minimizing actual structural complexity, resolving the contradiction between adaptability and device complexity
3Ease of operation
If the handle is angled away from the blade centerline, then forward thrusting becomes more natural and comfortable, but the blade cannot be held in a conventional inline position
Solution Approach 1:
The blade is designed with differentiated local qualities: the cutting edge is optimized for slicing motions while the spine area features a sharp point optimized for thrusting. This local specialization allows the blade to excel at thrusting when held in the pistol grip configuration, making the angled handle position highly effective for its intended purpose, thus resolving the contradiction between thrusting comfort and handling versatility

AI summary
The device discloses a thrusting knife of improved design which provides for an angled handle to allow more natural thrusting movements in hand to hand combat situations. The knife is comprised of a pistol grip-like handle which is more natural for a user to hold and provide a striking action with more natural wrist position when in use. The invention is more readily adaptable by individuals already trained in fist fighting tactical pistol drawing and placement or other self defense or combat arts. An index finger opening at the interface of the pistol grip and blade provide for improved control. An alternate embodiment is configured for use with a gloved hand.
