TechDry Tools manufactures specialty drywall finishing tools optimized for small repairs, tight spaces, and precision finishing around doors frames, corners, and edges. They developed the original Dry-X3 multi-blade drywall finishing knife, which combines three detail blades in one tool for quick switching between different blade sizes during touch-ups. It features an aluminum housing, and a pressure-lock mechanism that secures the selected blade while storing the others inside the handle.
