Relatively common stainless steel blade made of a stamped part in an Asian variant of the basic 420J2, grind concave chisel laser-cut, all drenched with oil. This is clearly of industrial at best semi-industrial, but for the price, including shipping, it's still very honest and made a small package very sharp knife, easily replacing a cutter. But it is by far the charm of an old Higonokami. As for me I did not get the tea bag (not affect the note).
