The hole in the tip hardware has been curved. Have you ever had the Dyneema line on your choke break when pulling a fish hidden in the rocks?? "Huh? I didn't pull that hard... It said it could handle 〇〇kg!" This is because when the tension is applied to the line and it rubs against the rocks, even strong Dyneema can be easily cut. Even climbing ropes, which are designed to save lives, will gradually break if they are under load and rubbed against rock faces. This hardware prevents the Dyneema from being worn down. * Full carbon, hardware made of stainless steel * The shaft is 12.8mm, making it slim while also considering ease of grip. * Using a thick 3.3mm carbon pipe, it is stronger than shafts of the same diameter. Some people who have experienced breakage with extreme tapers or thin-walled shafts may purchase this. * Can be used with either 2 or 3 shafts. Can be replaced simply by turning the screws. * All spear tips sold by anzyproduct can be used. * Shaft replacement and extension are possible. We will also make replacements if you "lost the shaft in murky water," etc. \#anzyproduct's spear list ↑↑ You can compare ＜Specs＞ 2-piece Weight: 545g 3-piece Weight: 815g Hardware, push rod, and choke use stainless steel ＜Full Carbon Shaft＞ Tip: Outer diameter 12.8mm, wall thickness 3.3mm, length 125cm Middle: Outer diameter 12.8mm, wall thickness 3.3mm, length 125cm Rear: Outer diameter 12.8mm, wall thickness 3.3mm, length 125cm ＜Stainless Steel Push Rod＞ Diameter: 7mm Total Length: 40cm Weight: 110g ＜Stainless Steel Choke＞ Diameter: 7mm Hole Diameter: 5.05mm ＜Titanium Rest Hook, Sling Charge＞ It takes time to pull the rubber band after finding a fish.
