1. A method of machining intricate cuts in a work piece comprising: cutting a work piece to form an aperture approximating a desired shape having at least one acute angle, wherein each acute angle of the desired shape is approximated by a cut having a corner radius;inserting a tapered elongate member of a first cutting apparatus into the aperture;pushing the tapered elongate member through the aperture to remove material from the work piece;inserting a tapered elongate member of at least one additional cutting apparatus into the aperture; andpushing the tapered elongate member through the aperture to remove material from work piece, thereby forming the desired shape having at least one acute angle. 2. The method of claim 1 further comprising: mounting the first cutting apparatus to a reciprocating member; andoperating the reciprocating member while pushing the tapered elongate member through the aperture. 3. The method of claim 1 further comprising: sequentially inserting the additional tapered elongate member of the at least one additional cutting member in order of increasingly finer abrasive surfaces to achieve the desired shape; whereinthe tapered elongate member of the at least one additional cutting apparatus has a finer abrasive surface than the first cutting apparatus. 4. The method of claim 1 further comprising: sequentially inserting the one or more additional elongate members having increasingly less taper to achieve the desired shape; whereinthe additional tapered elongate member of the at least one additional cutting apparatus tapers less than the first cutting apparatus. 5. The method of claim 1 further comprising: inserting increasingly shorter cutting apparatuses to achieve the desired shape; whereinthe additional tapered elongate member of the at least one additional cutting apparatus has a shorter length than the first cutting apparatus. 6. The method of claim 1 further comprising: mounting the work piece on an ultrasonic device;placing the work piece at least partially in an abrasive slurry; andagitating at least one of the work piece and the abrasive slurry with the ultrasonic device. 7. The method of claim 1 further comprising: mounting the first cutting apparatus on an ultrasonic device;placing the first cutting apparatus at least partially in an abrasive slurry; andagitating at least one of the first cutting apparatus and the abrasive slurry with the ultrasonic device. 8. The method of claim 1 wherein cutting a work piece to form an aperture comprises using a computer numerical controlled mill. 9. An apparatus for machining intricate cuts in a work piece comprising: a first member configured to cut a work piece to form an aperture approximating a desired shape having at least one acute angle, wherein each acute angle of the desired shape is approximated by a cut having a corner radius;a tapered elongate member extending from the first member and configured to be inserted into the aperture, the tapered elongate member having a taper that extends along a length of the tapered elongate member towards a distal end of the tapered elongate member; whereinthe tapered elongate is configured to remove material from the work piece, thereby forming the desired shape having at least one acute angle. 10.
