Demi Bullnose Edge

A demi bullnose edge on a countertop is a type of edge profile that is characterized by a rounded edge that is shallower than a full bullnose, but deeper than a half bullnose. This edge profile is created by removing a small amount of material from the top edge of the countertop, creating a curved edge that slopes downward.
 
This edge profile can be created by using a specialized router bit or by hand-carving the edge. It's commonly used in natural stone countertops like granite or marble, but can also be used with other materials like engineered stone, quartz or solid surface.
 
A demi bullnose edge profile can add an elegant and refined look to the countertop and it can make the countertop more comfortable to use, as it eliminates sharp edges. It's a functional edge, as it makes cleaning and wiping down spills, crumbs, and other debris much easier. Additionally, it can also be helpful to avoid injury of sharp edges.
 
This edge profile is a subtle design touch that can add a refined look to the countertop and it's a great option for countertops in areas where a clean and modern look is desired, such as kitchen counters or islands, or for countertops that will be used in heavy-use areas. It is considered as a middle ground between a half and full bullnose edge and it can be used in places where a subtle rounded edge is desired but not as pronounced as a full bullnose.
