LEVEL5 4" Welded Stainless Steel Joint Knives OVERVIEW A joint knife (or “putty knife”) can be found in the back pocket of most drywall finishers. These versatile tools are used for setting & cutting drywall tape, applying joint compound & other filler materials, cleaning up drywall edges, scraping paint & residue, resetting exposed screws, and much more. LEVEL5 offers the highest quality one-piece welded knives in the industry. 17 assembly steps and nine hand polishing steps are required to make each knife and a patent pending, full tang design with 3 internal points of control provides outstanding durability. Other features include a curved design where the handle meets the blade to enhance rigidity for a perfect mid-blade flex, and all robotically-welded seams have been mirror polished until undetectable. VERSATILE » Ideal for setting & cutting drywall tape, applying joint compound & other filler materials, cleaning up drywall edges, scraping paint & residue, resetting exposed screws, and much more! SUPER COMFORTABLE » LEVEL5 grip profile was developed through years of finisher feedback to minimize hand fatigue.

EASY CLEANUP » Mirror polished to reduce mud accumulation These knives are lightweight, extremely comfortable in the hand, and clean up like a dream.
