Scraping tools that deburr multiple edges of a part

An apparatus comprising:

• a frame defining a C-shaped channel comprising two walls and a base member;
• and
• stationary blades within the C-shaped channel that are secured along and obliquely oriented to the walls of the C-shaped channel such that for each cutting edge of each of the stationary blades, a line coincident with the cutting edge intersects a wall of the frame and the base member of the frame,
• wherein the stationary blades positioned along a respective wall have a same orientation, each of the stationary blades is obliquely oriented with respect to a corresponding wall, the stationary blades positioned along different walls extend for less than half of a width of the C-shaped channel, and each of the stationary blades slopes downwards from a corresponding wall towards the base member,
• wherein the stationary blades are each removably secured to a blade mount proximate to an orifice in the blade mount that is dimensioned to receive a fastener that secures the stationary blade in place, wherein the orifice defines a central axis oriented oblique to the two walls and the base member;
• and
• wherein the frame comprises the respective blade mounts.

An apparatus comprising:

• a frame;
• a first set of stationary blades mounted to the frame that are arranged in series along a length of a first side of the frame such that for each cutting edge of each of the stationary blades in the first set, a line coincident with the cutting edge intersects the first side of the frame and a base of the frame;
• and
• a second set of stationary blades mounted to the frame that are arranged in series along the length of a second side of the frame such that for each cutting edge of each of the stationary blades of the second set, a line coincident with the cutting edge intersects the second side of the frame and the base of the frame,
• wherein the second side of the frame faces the first side of the frame,
• wherein the stationary blades in the first set have the same orientation that is angled towards an interior portion of a channel defined by the frame, and the stationary blades in the second set have an orientation that is mirrored with respect to the stationary blades in the first set,
• wherein the stationary blades are each removably secured to a respective blade mount proximate to an orifice in the blade mount that is dimensioned to receive a fastener that secures the stationary blade in place, wherein the orifice defines a central axis oriented oblique to one of the first side and the second side of the frame, and to the base of the frame;
• and
• wherein the frame comprises the respective blade mounts.
