KAESU TINY MASAMUNE 100/120 – The Ultimate I-Shaped Swimbait
The KAESU Tiny Masamune 100 & 120 are next-generation I-shaped swimbaits designed to trigger bites from even the most selective bass. Engineered with a water-through duct system and a micro-vibration elastomer tail, this lure perfectly mimics a baitfish that has strayed from the school, swimming weakly in open water—an easy target for opportunistic predators.
Unlike traditional swimbaits, the Tiny Masamune maintains a straight, no-action body while the tail produces subtle vibrations, creating a lifelike, panic-stricken movement that convinces even the most cautious bass to strike. With an adjustable buoyancy system, it can be instantly switched between floating and sinking, allowing anglers to adapt to changing conditions and fish anywhere from the surface to mid-range depths.

Body Form & Hook Setting
The slim 100mm body is carefully designed to match the size of baitfish commonly found in various fishing environments. Its profile makes it an irresistible meal for bass of all sizes, from average catches to trophy-class monsters.

The feathered hooks enhance the lure's visual appeal by subtly altering the silhouette based on retrieval speed. This natural swaying motion adds an extra level of realism, increasing bite rates and enticing even the most hesitant fish.

Water-Through Duct – True No-Action Stability
- The water-through duct system channels water through the body, eliminating unwanted movement and keeping the lure perfectly stable.
- Ensures no unintended action, regardless of rod movements or line tension, maintaining a completely natural swimming posture.


Micro-Vibration Elastomer Tail – Subtle Yet Deadly
- The soft elastomer tail produces a slight high-frequency vibration, imitating the subtle movements of a real baitfish.
- This vibration is just enough to attract predatory bass without alerting them to an unnatural presentation.
Insert Plate Weight – Instant Buoyancy Adjustment
- Allows anglers to switch between floating and sinking modes quickly and efficiently.
- Adapt instantly to fish activity levels, depth preferences, and field conditions without sacrificing lure performance.


Slim Profile & Hook Optimization
- The 100mm and 120mm body sizes are perfectly proportioned to match natural baitfish found in any fishing environment.

- Feathered hooks enhance the lure’s silhouette at different retrieval speeds, creating a natural, swaying motion that increases bite rates.
