Filling Knife Sourcing 2K 100 mm – hand tool for cutting and filling materials

The Sourcing Filling Knife 2K 100 mm is a handheld tool designed for cutting, applying and smoothing filler, putty and similar compound materials. The 100 mm stainless-style blade offers a straight working edge for even spreading and precise finishing. The 2K handle combines a harder core with a softer overmold to improve grip and control during repetitive tasks, providing steadier handling when renovating walls, finishing joints or carrying out DIY repairs.

Advantages

The two-component (2K) ergonomically shaped handle reduces hand fatigue and improves handling accuracy for detailed work. The moderately flexible flat blade enables both cutting of tape and removal of excess compound, as well as smooth finishing strokes without digging into the surface. The compact 100 mm blade length provides a balance of reach and maneuverability, making the tool suitable for narrow areas and edge work. The tool is lightweight and easy to clean after use.

How to use

Hold the filling knife by the 2K handle with a comfortable grip and position the flat blade at a shallow angle to the surface.

To level and finish, use longer smooth passes and adjust pressure to avoid gouging. For cutting or removing excess material, use the blade edge with a controlled scraping motion. Clean the blade and handle after use to prevent buildup and preserve performance.
