Each sharkfin has a hole providing three options to connect the shooting line.
The shafts are made using 17-4PH heat treated stainless hardened to 47 Rockwell.
The new barb is produced using the same steel (47Hrc) for increased strength.
The hole for the pin that holds the barb in placeand the pin itself-are recessed completely.
Thanks to this feature, the penetration in the flesh of the prey is greatly increased.
The shark fins are produced by MIM (metal injection molding).
