Description

Meticulously engineered for dental laboratory and plaster room workflows, the premium #7R Lab Plaster Knife is an essential tool designed for the precise trimming, scraping, and shaping of gypsum, plaster, and investment models. The blade features a robust, high-rigidity silhouette optimized to cut through dense stone or plaster blocks without flexing or skipping. This specific geometric design allows technicians to cleanly remove flash material, define anatomical margins, and carve precise relief areas on models with total control and minimal physical effort.

Prioritizing user safety and physical control during high-resistance trimming tasks, this classic laboratory knife is outfitted with a contour-finished wooden handle that provides a warm, ergonomic, and non-slip grip. The tool measures 14cm in total length, offering an exceptionally well-balanced hand feel that maximizes mechanical leverage while allowing for fine, detailed hand movements. Forged from high-carbon surgical stainless steel and securely riveted to its hardwood core, this heavy-duty knife is built to resist corrosion from wet gypsum slurries and maintain its structural reliability over long-term intensive lab use.

Key Features & Technical Specifications

• Rigid Gypsum-Cutting Blade: Specially tempered steel blade engineered to carve, trim, and scrape tough plaster and dental stone models without structural bending.
• Ergonomic Wooden Handle: Equipped with a premium, natural wood handle that cushions the hand, improves tactile feedback, and ensures a secure grip when wet.
