Generally, when culturing pearls, a trained craftsman cuts the mantle of the Akoya oyster (cellular oyster) into small pieces using a cell scalpel, and then cuts into the intestine of the Akoya oyster (mother oyster) using a leading scalpel. A pearl sac is formed inside the body of the Akoya oyster (mother oyster) by inserting the ball (bead) that becomes the nucleus of the pearl and the above-mentioned small piece through the same notch, and the pearl sac is formed inside the pearl sac. A method of forming pearls is used. Since the Akoya oyster is a saltwater bivalve, the above-mentioned cell female and lead female (hereinafter referred to as "pearl culture female")
In order to meet these requirements, pearl culturing females are often made of stainless steel.

However, in the conventional pearl culture scalpel as mentioned above, since it is made of stainless steel, it can prevent rust, but on the other hand,
The lack of sharpness causes large scratches on the Akoya oyster (mother oyster), which takes a considerable amount of time to recover from, making it impossible to obtain high-quality pearls.
In order to maintain the sharpness of pearl culturing scalpels,
The problem is that the pearl culturing scalpel has to be polished several times every day, which reduces the efficiency of the actual operation of inserting the nucleus.

に対してろう付けにより一体化される。 FIG. 1 is a drawing showing an example in which the present invention is applied to a leading scalpel. In the same drawing, 4 is a handle portion formed in a long cylinder shape, and 5 is a leading scalpel (scalpel for pearl cultivation) for making an incision in the intestine of the Akoya oyster (mother oyster). A base portion of a handle 6 is inserted into one end of the handle portion 4 along the axial direction to be detachably connected. Further, the leading scalpel 5 consists of the handle 6 formed in the shape of a round bar and a blade 7 formed at the tip of the handle 6, and the handle 6 is made of stainless steel. The blade 7 is made of cemented carbide, and is integrated with the tip of the handle 6 by brazing.
