Abstract

La présente invention porte sur un guide à arête de protection pour ciseaux. Dans certains modes de réalisation, le guide à arête de protection est formé d'un seul tenant avec un bras d'une paire de ciseaux. Dans d'autres modes de réalisation, le guide à arête de protection est fixé amovible à la surface extérieure d'un bras de ciseaux. De préférence, le guide à arête de protection se présente sous la forme d'un arc s'étendant de façon à s'éloigner à partir de la surface intérieure du bras si le guide est formé d'un seul tenant avec le bras, ou à partir de la surface extérieure si le guide est fixé amovible à la surface extérieure. Par la forme et la position du guide à arête de protection sur le bras d'une paire de ciseaux dans certains modes de réalisation, le guide à arête de protection est ergonomique et accroît la sécurité de l'opérateur des ciseaux sans interférer avec les techniques de coupe de l'opérateur.
