In 1976, five years after the start of research, we became the first in the world to produce eyeless needles using laser beam drilling technology. The bonding technique, whereby the suture thread is inserted and bonded to the needle hole, makes damage to the tissues less likely and enables exceptionally smooth penetration.

We pursued opposing qualities such as toughness and hardness to create our original material, MANI hard-fiber stainless steel. By adding our original "seisen" process to 18-8 stainless steel, we were able to develop flexible and corrosion-resistant needles.

We develop testing and evaluation machines in addition to forming machines in order to draw maximum benefit from the material characteristics and original technologies arising out of our accumulated research results. With this original testing and evaluation technology, we pursue "the best quality in the world".
