Keitech Swing Impact

Throughout much of the winter of 2019-20 and into the spring of 2020, Mike Czaplinski of Branchville, New Jersey, who is the proprietor of KeitechUSA, began informing us about several dainty soft-plastic baits that Midwest finesse anglers could add to their repertoire.

One of them is the 2 1/2-inch Swing Impact.

Czaplinski provided us with a package of them to work with and perhaps publish a gear guide about them.

Here is what we discovered about them.

It is what Midwest finesse anglers would describe as a super-finesse swimbait.

According to our measurements, it is 2 11/16 inches long when its paddle tail is fully extended.

Its head possesses an oval-shaped dome with a smooth epidermis. It is 3/16-inch long with a width of 3/16-inch at its widest spot and a circumference of about 7/8-inch. It has a height of 5/16-inch at its highest spot. At the tip of the head, there is a slight indentation, which is where a Midwest finesse angler will insert the hook and bait keeper of a small jig.

From its junction with its head to its junction with its tail, the torso is 2 3/16 inches long. It is encircled with 29 ribs. The torso is somewhat oval shaped. At rib number one, it is a 1/4-inch wide with a circumference of about 15/16-inch and a height of 5/16-inch. Rib number 10 is situated 1/2-inch from the tip of the head, and it has a width of a 1/4-inch, a height of 5/16-inch and a circumference of one inch. The circumference, height, and width of the torso diminishes in size between ribs number nine and 29. At rib number 29, which is adjacent to the beginning of the torso’s caudal peduncle area, the torso has a width of 1/16-inch, a height of 3/16-inch and a circumference of about 7/16-inch.

The caudal peduncle area is a 1/2-inch long with a smooth epidermis. It is thin and flat with a thickness of about 1/16-inch. Near the junction with rib number 29, the caudal peduncle has a height of 1/8-inch. At its junction with the Swing Impact’s paddle- or boot-style tail, the caudal peduncle possesses a flange-like shape with a height of 3/8-inch.

The tail is thin with a smooth epidermis. It has an oval shape. It has a height of 7/16-inch. It is 3/8-inch wide at its widest spot. It is about one millimeter thick.

It is manufactured in the following hues: Ayu, Bluegill Flash, Chartreuse Shad, Electric Blue Gill, Electric Shad, Green Pumpkin Candy, Green Pumpkin Chartreuse, Green Pumpkin Pepper, Male Perch, Morning Dawn, Pro Blue Red Pearl, Sexy Shad, Shad, Sight Flash, and Smallmouth Magic,

It is manufactured with a dual-injection molding process with two different salted plastics. It is buoyant and infused with a strong squid scent.

Besides the 2 1/2-incher, the Swing Impact is made in four other sizes. According to Czaplinski, the Swing Impact was created in 2009 by the late and great Kei Hayashi of Yamanashi, Japan. His first renditions were 3 1/2 inches and 4 inches long. The 3-inch model debuted in 2013. The 2-inch, 2 1/2-inch and 4 1/2-inch Swing Impacts were added to Keitech’s repertoire in 2015. And Czaplinski notes that nowadays the bass fishing world has finally “discovered the swimming attributes of the smaller sizes” of the Swing Impact.

A 2 1/2-inch soft-plastic bait affixed to a small jig with an exposed hook has played a dominant role in the repertoire of Midwest finesse fishing for decades. And in its infancy, the pioneers of Midwest finesse fishing were often belittled as “crappie fishing for bass” when they were seen by their power-fishing brethren using a rig the size of the 2 1/2-inch Swing Impact on a tiny jig. But those denunciations have subsided dramatically during the past three years.
