The ferrule connecting the rod is TOUGH BUTT FERRULE, which combines carbon with carbon to increase the strength. However, what is important is that this ferrule firmly holds the blanks and butt together as one rod. No matter how lightweight and powerful the blanks are, they will not show their true value if they rattle in actual fishing. CHERMARE OTOSHIKOMI is equipped with a nut mechanism that is "easy to tighten and hard to loosen" without any compromise in ferrule fixation. The tightening nut is not just a double nut, but "a reverse screw specification". The nuts create greater friction than when tightened in the same direction, and since they tighten against each other, they are less likely to loosen, and even when humans tighten the nuts, they can be tightened by applying force efficiently. Furthermore, by adopting a nut for fixing the reel, which is wider than that of the conventional model, rattling of the reel is also reduced. This enables secure setup not only at home or in harbors, but also on boats in a hectic and shaky environment.

SHIMANO's original aluminum seat adopts a sophisticated design to hold the reel firmly even when fighting with very large fish. The parts that hold the reel legs have a flat design for even greater holding power. Also, a resin cushion is equipped to prevent the reel from rattling and scratches, and the nut used to hold the reel has been improved in a shape to make it easier to tighten. In addition, a double nut with a cushion is attached to prevent loosening after tightening.

Reviewing the shape of the conventional fighting bottom, the belly side of bite surface was flattened and the bottom area was enlarged. At the same time, rubber was installed on the bottom to prevent slipping and the rubber at the fitting part was improved to prevent dropout, resulting in a highly practical power fighting bottom that pursues no pain, no slipping, and no falling off.

To prevent slipping of the holding position while the rod set on the ground, such as when moving, the diameter of the holding position is optimized and at the same time the number of grooves is increased to prevent slipping.
