Many people are hesitant to do thread wrapping, thinking, "Can I do it neatly?". This allows you to easily make your spear into a thread wrap grip specification. You can rest your hand or fingers by hooking them on the thread-wrapped part. Compared to just attaching an anti-slip grip, you can reduce the necessary grip strength by nearly half when the rubber is stretched. Your hand and fingers will firmly grip the shaft. We can accommodate multiple purchases if you leave a comment. ＜Size＞ It will definitely fit the size of our spears. It can also be used with other companies' spears with an outer diameter of 18mm to 11mm. ＜How to Use＞ 8 rings that are resistant to seawater and do not slip on the shaft are included per 1m. Determine the ring position that will be the protruding part on the shaft. This is the place on the shaft where you grip when pulling the rubber. Cover it with the anti-slip tube and shrink it with a gas burner. Search YouTube or the internet for "heat shrink tube" and you will find many videos. Basically, it is shrunk with a heat gun, but our recommendation is a gas burner for barbecues and outdoor use. The trick is to avoid burning by applying the heat about 10 cm away from the red flame, and you will get a beautiful finish. Imagine broiling eel and slowly rotate while applying heat to shrink it, and you can get a beautiful finish. ＜Specs＞ Inner diameter before shrinkage: 20mm Inner diameter after shrinkage: 10mm Thickness after shrinkage: 1cm～ Shrinkage ratio: 2:1
