Claim:
1. A monofilament metal saw wire for use as a wire saw when coated with a slurry of abrasive material, the metal saw wire comprising: a substantially circular cross-sectional shape with a diameter d, a plurality of crimps having a zigzag form, wherein said crimps are arranged in at least a first plane and a second plane distinct from said first plane, said crimps in said first plane having a first wavelength and said crimps in said second plane having a second wavelength, said first wavelength being longer than said second wavelength and said first wavelength is not an integer multiple of said second wavelength, wherein said crimps in said first plane and said second plane provide recesses where the abrasive material of the slurry sits during entrainment, and wherein when measured, between measuring rods of a micrometer, over a length comprising crimps in said first plane and said second plane, a circumscribed enveloping diameter D of said crimped saw wire is between 1.05 and 1.50 times said diameter d.
