The O.S.P Sinker Direct is a sinker designed with the performance required for the bottom game that is required in a wide range of fishing scenes, regardless of fish species. The required performance is to fly well, sink straight quickly, and have high bottom sensing ability while stepping over obstacles. To meet these requirements, dozens of test samples are verified in the field. What we arrived at was a shape with a low center of gravity and a rounded top of the main body. This shape avoids stacking in the gaps of rocks and wave-dissipating blocks, and also reduces damage to the inner pipe through which the line passes because the top of the main body is difficult to hit obstacles. The inner diameter of the inner pipe is designed to take into account the thickness of the line used, for example, in a free rig, the worm and sinker are easier to separate, allowing for natural lure. The shape named Waist Edge does not slip too smoothly against the undulations and stones of the bottom, but it still plays a role in clearly conveying terrain information to anglers, and as a result, it greatly contributes to rooting avoidance. The O.S.P direct sinker, which has a high level of performance required for actual fishing, overturns the concept of "just a sinker".
