Abstract
A blade including a body has a front surface and a curved back cutting surface. The front surface has a mount angle relative to a material surface of a material facing the back cutting surface. The back cutting surface has a substrate clearance angle relative to the material surface. In response to at least one of the blade and the material surface being brought into cutting contact and moved relative to each other, a resulting portion of the material surface has a distressed appearance.
Claims21
An apparatus for distressing a material surface of a material, the apparatus comprising:
- a blade support;
- a blade supported by the blade support;
- a material support defining a material support plane, the material support interconnected with the blade support;
- the blade comprising a body having a front planar surface, a rear surface opposite the front planar surface, and a curved back cutting surface of between about a 12 inch radius and about an 18 inch radius, the front planar surface and the curved back cutting surface intersecting at a tip, the rear surface and the curved back cutting surface intersecting at a rear edge, the front planar surface forming an acute blade angle with the curved back cutting surface;
- the blade support supporting the blade in an orientation so that an obtuse mount angle is formed between the front planar surface of the blade and the material support plane, and the back cutting surface forming an acute substrate clearance angle with the material support plane, wherein the front planar surface of the blade forms the obtuse mount angle with the material support plane without passing through the blade or the material support plane;
- and
- the blade support and the material support configured to create relative movement between the material supported on the material support and the blade such that the blade contacts the material surface of the material and moves along the material surface of the material in a first direction, the front planar surface facing the first direction.

A method of distressing a material, the method comprising:
- positioning a material on a material support, the material having a planar material surface;
- providing a blade having a body having a front planar surface, a rear surface opposite the front planar surface, and a curved back cutting surface of between about a 12 inch radius and about an 18 inch radius, the front surface and the curved back cutting surface intersecting at a tip, the rear surface and the curved back cutting surface intersecting at a rear edge;
- positioning the blade so that an obtuse mount angle is formed between the front planar surface of the blade and the planar material surface, wherein the front planar surface of the blade forms the obtuse mount angle with the planar material surface without passing through the blade or the planar material surface;
- directing the blade and the planar material surface into cutting contact;
- and
- moving at least one of the blade and the planar material surface relative to each other so that the blade moves along the planar material surface of the material in a first direction and chatters during said movement, the front planar surface facing the first direction.

A method of distressing a material, the method comprising:
- positioning a material on a material support, the material having a planar material surface that defines an X-Z plane of a Cartesian coordinate system;
- providing a blade having a body having a front planar surface, a rear surface opposite the front planar surface, and a curved back cutting surface having a radius, the front surface and the curved back cutting surface intersecting at a tip, the rear surface and the curved back cutting surface intersecting at a rear edge;
- orienting the blade so that:
- (1) a Y-Z plane of the Cartesian coordinate system intersects the tip of the blade;
- (2) the front planar surface of the blade forms an obtuse mount angle with a portion of the planar material surface lying in a positive X sector of the Cartesian coordinate system;
- and (3) the front planar surface of the blade forms an acute mount angle with a portion of the planar material surface lying in a negative X sector of the Cartesian coordinate system;
- directing the blade and the planar material surface into cutting contact while maintaining the blade in said orientation;
- and
- moving at least one of the blade and the planar material surface relative to each other while maintaining the blade in said orientation, wherein during said movement the Y-Z plane of the Cartesian coordinate system remains in intersecting relation with the tip of the blade and the portion of the planar material surface lying in the positive X sector passes through the Y-Z plane into the negative X-sector, thereby becoming distressed by the blade, and the blade chatters during said movement.
