This is a self-made, small, tangle-resistant tenbin (fishing weight) for boat fishing for kiss and hazer. It improves fishing performance with different sizes of fishing weights and precise weight and length. Commercially available ones had trouble with the line getting caught in the opening of the tenbin, making it difficult to remove. So, I closed the opening with silver solder, and it worked. I applied this to my existing tenbin, and the frustration disappeared. The approximate dimensions of each part by number are shown in the attached photos. Thank you for looking.
