The Rob Allen Drop Barb 7.5 mm speargun shaft is a heavy-duty spear for hunting large, powerful fish where maximum penetration and holding power matter. Made from spring steel hardened to 2100 MPa, it resists bending under load, and the reinforced stainless steel drop barb helps keep the fish on the shaft once it is hit. It is made in South Africa by Rob Allen, a brand known for robust, reliable spearfishing gear.
