Sōchí K String
Sochi - Kohei Nishimura Signature String. Championship Precision.
The K String by SOCHI is the signature string of Kohei Nishimura, 2023 Japan National 1A Champion and master of extreme hook variations. Designed specifically to support Kohei’s signature 4.0 hook combos, this string was developed with a single goal in mind—to make high-level slack tricks more accessible to every player.
K String features a custom thickness that falls perfectly between SOCHI’s “Fat” and “XL” sizes. This optimized density delivers fast, responsive slack movement while maintaining excellent control and consistency throughout high-speed play.
A carefully blended material construction includes white threads for fine-tuning both appearance and feel, creating a string that not only plays well but looks clean in motion. The result is a string that offers smooth string movement, lightning-fast slacks, and a soft, forgiving feel on the hands.
Kohei Nishimura on K String: “I used a prototype of this string at Japan Nationals in 2022. It keeps the smooth feel and fast slack response of previous SOCHI strings but adds a softer touch that makes it even easier to control. It's consistent, comfortable, and works exactly how I need it to.”
Whether you're chasing your first 3.0 hook or grinding out competition-level slack tech, K String delivers the performance and feel trusted by a national champion.
