SCISSORS

摘要

Scissors include two scissor members. The two scissor members are pivotably connected with a joint member. The each scissor member includes a blade portion linked to a connecting portion. The blade portion includes a curved blade and an intermediate portion width between a tip and a base portion is made widest. The curved blade includes a receding portion between an end portion of the base portion side and a side edge of the connecting portion and is formed such that a curvature is larger at a base portion side than a tip side. An arc-shaped surface groove is formed on a rear surface of the blade portion along the curved blade. The blade portion is formed such that the rear surface thereof is formed in a concave shape so as to form the arc-shaped surface groove.

1. Scissors comprising:
two scissor members being pivotably connected to each other with a joint member at connecting portions, wherein the each scissor member includes a blade portion which is linked to the connecting portion, each of the blade portion includes a curved blade which is a cutting blade formed in an arc-like curved shape from a tip to a base portion and a width of the blade portion is made to be widest at an intermediate portion between the tip and the base portion, an end portion of the curved blade which lies at the base portion is caused to recede further away from a side edge of the connecting portion so as to form a receding portion between the end portion of the curved blade which lies at the base portion and the side edge of the connecting portion, and an arc-shaped surface groove is formed along the curved blade on a rear surface of the blade portion.
