Plaster Knife

The Plaster Knife is an indispensable tool in every dental laboratory, designed specifically for carving and shaping both wax and plaster models. Its thick, sharp blade allows technicians to execute fine cuts with precision, while the secondary function on the opposite end enables quick opening of plaster flasks, streamlining the workflow from impression to finished cast.

By opting for the Plaster Knife, dental practitioners benefit from a highly durable, dual-purpose instrument that reduces the need for multiple tools. Its reliable construction ensures consistent performance, helping lab technicians achieve cleaner cuts, fewer errors, and ultimately faster turnaround times for patient-specific restorations.
