How to use

Ensure the finishing knife is clean and free of cured compound before fitting a new blade. Carefully align the replacement blade with the knife holder and secure it according to the knife manufacturer’s fastening method. Use the blade to spread compound in smooth, even strokes, holding the knife at a shallow angle to feather edges. Replace blades when the edge becomes nicked or the finish quality declines to maintain consistent results.

Usage recommendations

For best results, store blades in a dry place to avoid corrosion and handle with care to prevent cuts when fitting or disposing of used blades. Match blade replacement frequency to the workload: professional settings may require changing blades more often to preserve finish quality, while light DIY tasks may allow multiple uses per blade.
