UNIVERSAL SCISSORS (VARIANTS) Russian patent published in 2024 - IPC A61B17/3201 B26B13/12 B26B13/28 

FIELD: hand-held cutting tools.

SUBSTANCE: group of inventions relates to a finger-grip design for cutting tools such as universal scissors. The utility scissors include the first arm, the second arm, and the first finger grip. The second lever is pivotally connected to the first lever on the rod. Each lever is rotatable from an open position to a closed position. Each lever has a blade. The blades in the closed position form a longitudinal axis. The first finger grip is formed on the first lever. The second finger grip is formed on the second lever. The first finger grip includes a flat inner surface adapted to receive the thenar of the user's thumb. The second finger grip defines the second inner surface adapted to receive at least one finger of a user such that the combined pressure of the thenar on the flat inner surface and at least one finger on the second inner surface moves the first lever and the second lever into a closed position. The flat inner surface extends generally parallel and offset relative to the longitudinal axis when the first lever is in the closed position. In the second variant, the utility scissors comprise the above-mentioned first lever, second lever and first finger grip. The first finger grip further includes a lower part. A flat inner surface is formed from the lower portion, and the flat inner surface and the second inner surface formed by the second finger grip are generally parallel to each other when the first arm and the second arm are in the closed position.

EFFECT: group of inventions is characterized in that the configuration of the first grip provides an even distribution of force across the thenar or elevation of the thumb and thenar muscles, while the absence of curvature and protrusions on the surface eliminates the concentration of force on the thenar muscles, preventing potentially significant pain for the user.
