摘要：A diamond-nickel blade for cutting electronic crystals and substrates or the likecomprising diamond particles in a nickel matrix. The nickel matrix is the sole support forthe blade and the volume of the nickel matrix is no greater than about 55% of thevolume of the blade. Such blades are made by immersing a flat, electrically conductivesubstrate in a suspension comprising diamond particles in an electrolyte;

electrodepositing nickel in an annular pattern corresponding to the desired shape of theblade on a surface of the substrate, the electrodeposited nickel being only lightlyadherent to the substrate surface (diamond particles are thereby codeposited in thenickel which forms a matrix around them); and stripping the annular deposit of nickel anddiamond particles from the substrate. Also disclosed are blade- mounting meanscomprising two identical, lapped-surface collars and a ring.
