AI Technical Summary

Technical Problem

Existing utility knife blades tend to wobble when cutting hard objects or at deep depths, resulting in reduced cutting accuracy and easy breakage.

Method used

Reinforcing protrusions are added to the blade body to enhance the structural strength of the blade. By setting multiple sets of reinforcing protrusions along the length or height of the upper part of the blade, bending resistance and cutting stability are improved.

Benefits of technology

It improves the bending strength of the blade, reduces wobbling, enhances cutting accuracy, reduces the risk of breakage, extends service life, and is simple to process and low in cost.

Abstract

The invention belongs to the technical field of art knives, and particularly relates to an art knife blade. An art designing blade comprises a blade body, a blade part arranged on the lower portion of the blade body in the length direction of the blade body, and a reinforcing protrusion fixedly connected to the side face, opposite to the blade part, of the upper portion of the blade body in the length direction of the blade body. The reinforcing protrusions are arranged on the blade body, so that the bending strength of the blade is improved, and the cutting precision is improved.
