A method for forming a cutting tool includes masking a metal base with one or more masks, the one or more masks including at least one variable permeability mask, and chemically etching the masked metal base to form a blade of the cutting tool.

Chemically sharpening blades

A chemically etched needle is provided herein. The chemically etched needle includes a metal base having a first side and a second side. The chemically etched needle also includes a chemically etched blade at one end of the metal base and formed at an intersection of a distal diverging surface and a proximal diverging surface, at least one of the diverging surfaces slopes inward towards the second side.

A miniature camera () comprising at least one SMA actuator wire () arranged to effect focus, zoom or optical image stabilization. The SMA actuator wire () is coated with an electrically insulating layer () of thickness in the range from 0.3 &#x3bc;m to 10 &#x3bc;m. The layer () provides electrical insulation whilst permitting cooling that provides a rapid response time of the SMA actuator wire ().

A chemically etched cutting tool includes a metal base having a first side and a second side, and a chemically etched blade on at least one side of the metal base, the chemically etched blade forming a cutting edge at the intersection of the first side of the chemically etched blade and the second side of the chemically etched blade. The first side of the chemically etched blade includes one or more concave portions and one or more convex portions with at least one inflection point between the concave portions and one or more convex portions. The second side of the chemically etched blade includes one or more concave portions and one or more convex portions with at least one inflection point between the concave portions and one or more convex portions.
