The ProDec 50mm Scale Tang Flexible Filling Knife is a professional-grade decorating tool engineered for precise filler, sealant, and putty application. Its thin-profile stainless steel blade offers excellent flexibility, allowing smooth filling of cracks and holes. The full tang construction ensures durability and prevents snapping under pressure, while the varnished hardwood handle provides ergonomic comfort and reduces heat transfer—ideal when used with blowtorches for coating removal. A hanging hole adds convenience for storage, making this knife a reliable choice for decorators and tradespeople.
