## Description

3" All Stainless Steel Joint Knife - LEVEL5 | Professional Grade Putty Blade, Premium Polished All-Metal, Precision Ground Edge, Ergonomic, Corrosion Resistant | 5-403

## Features

- THE PROFESSIONAL'S CHOICE | LEVEL5 one-piece stainless steel joint compound knives feature a patent-pending, full length internal tang that has been robotically welded at four points of contact for extreme durability. The knives also feature robotically-welded seams that have been mirror polished. These knives are lightweight, extremely comfortable in the hand, and clean up like a dream.
- A PRECISION BLADE | Features a hollow-grind provides proper flex point midway up the stainless steel blade (versus near the handle).
