This is a stainless steel long chochki (spear point) with a total length of 8.5 cm. The diameter of the hole for passing lines such as Dyneema is 1.8 mm. The strength of the chochki in the middle has been increased. Usable Dyneema line thickness: Dyneema up to 1.5 mm in diameter can be passed through without processing or tools. With full Dyneema, 2 mm in diameter will barely fit. As shown in the image, you will need to wrap paper tape and cut it diagonally to make it easier to insert. Alternatively, enlarge the hole slightly with a drill. If you want to pass it through smoothly by hand without tools, choose Dyneema up to 1.5 mm. #anzyproduct's list of orange Dyneema ↑Click to see the listings Material: Stainless steel Diameter: 7 mm Total length: 8.5 cm Diameter of the hole for passing the line: 1.8 mm The chochki's release and smoothness are good. The surface of the hole where the push rod fits is smooth. The size design is done by us. We check the release from the push rod for all products, not just a sample, before shipping. If the release from the push rod is poor, we will exchange it free of charge. Sharpening the tip can be done with a metal file. With a grinder or disc grinder, you can quickly sharpen the tip. Regarding the curve of the wings, we have considered the balance between penetration and release and have added a curve. This product uses a resilient material, so the buyer can bend it with pliers, etc.
