Anzyproduct's harpoons are made one by one by a small number of craftsmen in our workshop. We carefully fine-tune them so that they remain straight even when multiple shafts are connected. We also design all of the metal fittings and carbon pipes ourselves, striving for strength and sturdiness. We also improve our vests and accessories every year to assist the spearmaster in his spearfishing efforts. We take pride in satisfying those who wish to pursue serious spearfishing.

We make sure that our customers do not have any trouble when it comes to shaft extension, additional purchases, or repairs. There have been zero incidents of "the screws did not fit" or "the size was wrong" with harpoon shafts, feather harpoons, and vests.

The shaft is made of carbon with the strongest manufacturing method for the same size. The inside is made of cheap and easily bent carbon, and no pipes are used to make the outside look pretty. It is made of only materials that can be called the muscles of the harpoon.
