Molding knives are an essential tool for any woodworker looking to create custom molding profiles for their projects. These knives come in a variety of shapes and sizes, and are designed to create intricate designs and shapes in the wood. In this article, we will explore what molding knives are, how they are made, and the different types of molding knives that are available.
What are Molding Knives?
Molding knives, also known as profile knives or cutter heads, are cutting tools that are used in woodworking to create decorative moldings and profiles. These knives are typically made from high-speed steel (HSS), carbide, or diamond-tipped materials, and are designed to be mounted on a planer or molder machine.
The blades of molding knives are specially designed with a specific profile or shape that can be used to create various types of moldings. These profiles can range from simple designs, such as a roundover or chamfer, to more complex shapes, such as ogee or cove.
How are Molding Knives Made?
Molding knives are typically made using a process called CNC (computer numerical control) grinding. This process involves using a computer-controlled grinding machine to shape the knife blade into the desired profile.
The first step in making a molding knife is to create a computer-generated design of the desired profile. This design is then loaded into the CNC grinding machine, which uses a diamond-tipped grinding wheel to shape the blade of the knife.
Once the blade has been shaped, it is heat-treated to harden the steel and improve its durability. The blade is then finished with a sharpening process that ensures the cutting edge is razor-sharp and ready to use.
Types of Molding Knives
There are several types of molding knives available, each with its own unique profile and design. Some of the most common types of molding knives include:
Crown Molding Knives: Crown molding knives(Click here for the Konetool Custom moulding knives) are used to create the decorative molding that is often found at the junction between walls and ceilings. These knives typically feature a complex profile that includes both concave and convex curves.
Baseboard Molding Knives: Baseboard molding knives are used to create the decorative molding that is found at the bottom of walls. These knives typically feature a simple profile that includes a rounded or beveled edge.
Chair Rail Molding Knives: Chair rail molding knives are used to create the decorative molding that is often found at the height of a chair back. These knives typically feature a simple profile that includes a rounded or beveled edge.
Cove Molding Knives: Cove molding knives are used to create the decorative molding that features a concave profile. This type of molding is often used to create a transition between a wall and ceiling or between two walls.
Ogee Molding Knives: Ogee molding knives are used to create the decorative molding that features an S-shaped profile. This type of molding is often used to add a decorative touch to furniture or cabinetry.
Roundover Molding Knives: Roundover molding knives are used to create a decorative edge on the edge of a board. This type of molding features a rounded profile and is often used to soften the edges of furniture or cabinetry.
