About our emblem

The outer frame symbolizes a hexagonal bolt, one of our main products. The inside is a pair of deformed golf clubs, expressing the founder's wish that the company would grow and pay its employees sufficiently so that they can play golf, which was a very expensive, aristocratic pastime in those days.
