Thisproved practicable, and although the groove so formed was notso easily fitted with a cutter blade on account of its curved sides,the curved sides gave the cutter a lip angle which was of greatvalue in actual service. To form the blades accurately to theshape of the groove, it was necessary to design a bending machine of great power, capable of squeezing the blades at once to
