Three Way Knives

Columbia Three-Way Knives
(Available for order and shipping today)

Columbia Tools is proud to launch our all-new Three-Way Knives – expertly designed to make finishing three-way drywall corners faster, cleaner, and easier than ever.

Made for Three-Ways

These knives take everything you love about our  Stainless Steel Nylon Handle Putty Knives—including the hammer head—and refine the blade shape specifically for three-way corners. A higher arch and earlier inward taper ensure the blade won’t interfere with the wall, giving you smooth, precise finishes where it matters most.

Key Features:

• Purpose-Built Blade Design:
  A high-arch profile and early inward cut keep the blade clear of adjoining walls, perfect for tackling three-way corners with confidence and control.
• Durable Nylon Handle with Hammer Head:
  Strong, lightweight nylon handle offers long-lasting comfort and grip, with an integrated hammer head for popping screws as you go.
• Stainless Steel Blade
  Flexible stainless steel blade delivers smooth application and consistent results, all at a competitive price point.

Built with the job site in mind and engineered for precision, Columbia Three-Way Knives help you finish faster, with fewer touch-ups and less frustration.
