MATERIAL SURFACE DISTRESSING BLADE
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 and the front surface define a blade angle. 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.
1 . A blade comprising:
a body having a front surface and a curved back cutting surface of between about a 12 inch radius and about an 18 inch radius,
the front surface having a mount angle of between about 92 degrees and about 98 degrees relative to a material surface of a material facing the back cutting surface,
the back cutting surface and the front surface defining a blade angle of between about 66 degrees and about 78 degrees; wherein
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 is distressed.
2 . The blade of claim 1 , wherein at least a portion of the back cutting surface defines a non-radial curve.
3 . The blade of claim 1 , wherein the non-radial curve is a portion of an oval.
4 . The blade of claim 1 , wherein the material is a cellulose-containing material.
5 . The blade of claim 1 , wherein the back cutting surface is between about a 13 inch radius and about a 17 inch radius.
6 . The blade of claim 5 , wherein the back cutting surface is between about a 14 inch radius and about a 16 inch radius.
7 . The blade of claim 6 , wherein the back cutting surface is about a 15 inch radius.
8 . The blade of claim 1 , wherein the mount angle is between about 93 degrees and about 97 degrees.
9 . The blade of claim 8 , wherein the mount angle is between about 94 degrees and about 96 degrees.
10 . The blade of claim 9 , wherein the mount angle is between about 95 degrees and about 96 degrees.
11 . The blade of claim 10 , wherein the mount angle is about 96 degrees.
12 . The blade of claim 1 , wherein the blade angle is between about 68 degrees and about 74 degrees.
13 . The blade of claim 1 , wherein the blade angle is between about 68 degrees and about 72 degrees.
14 . The blade of claim 13 , wherein the blade angle is about 70 degrees.
15 . The blade of claim 1 , wherein the material surface is substantially planar.
16 . The blade of claim 1 , wherein the body is composed of steel.
17 . The blade of claim 16 , wherein the body is composed of M2 tool steel.
18 . A blade comprising:
a body having a front surface and a curved back cutting surface of about a 15 inch radius,
the front surface having a mount angle of about 96 degrees relative to a material surface of a material facing the back cutting surface,
the back cutting surface and the front surface defining a blade angle of about 70 degrees; wherein
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 is distressed.
19 . The blade of claim 18 , wherein the material surface is substantially planar.
20 . A method for distressing a surface of a material comprising:
providing a body having a front surface and a curved back cutting surface of between about a 12 inch radius and about an 18 inch radius, a blade angle subtended between the front surface and the back cutting surface being between about 66 degrees and about 78 degrees;
positioning the front surface between about 92 degrees and about 98 degrees relative to a material surface of a material facing the back cutting surface;
positioning the back cutting surface between about 4 degrees and about 22 degrees relative to the material surface;
directing the blade and the material surface into cutting contact; and
moving at least one of the blade and the material surface relative to each other.
