10mm Spearfishing Euro Shark 4-Fin Mono Shaft (100–200cm) – 17-4PH Stainless Steel with 1 Flopper Barb for Speargun

The 10mm Euro Shark 4-Fin Mono Shaft is a high-strength spearfishing shaft designed for durability and reliable underwater performance. Manufactured from heat-treated 17-4PH stainless steel, this shaft offers excellent hardness, corrosion resistance, and long-lasting strength for repeated use in saltwater environments.

The shaft features four shark fins (3 loading fins + 1 rest tab) that are laser welded for enhanced structural strength and stability. A 1.2mm thick flopper with 60° barb angle provides secure hold during fishing operations. With a hardness level reaching approximately 45 HRC, the shaft maintains its straightness and resists bending even under demanding conditions.

Available in multiple lengths from 100cm to 200cm, this mono shaft is suitable for various speargun setups and fishing environments including oceans, lakes, rivers, and reservoirs.

Note: The shaft may show slight magnetism due to heat treatment of 17-4PH stainless steel. This is normal and does not affect corrosion resistance or performance.
