Abstract
A method of removing edges from an eyeless operating needle blank includes the steps of providing needle blanks having an end portion which defines a bore. Aligning the end portion, which defines a bore, longitudinally with a laser. The laser is fired such that radiation from the laser is incident on the end portion. The incident radiation from the laser forms rounded edges about the end portion.
