Karate Junction has had a long history with North West St. Paul. Originally called St. Paul Tang Soo Do, it was at that time a school that taught one specific type of Korean martial art called Tang Soo Do (now Soo Bahk Do). Over the years, it changed ownership and location. Then in 1999, the school was purchased by Deb Hall. Being a Master Instructor in Soo Bahk Do, she felt the foundation of the school needed to be Soo Bahk Do but she knew that in order for her business to grow she needed to diversify. The problem was that the identity system that she inherited connoted a very specific curriculum. She needed an identity system that could grow with her business without a confining perception of what her company was about.

The first step was to identify those elements that would not change over time. There were two; the name and the core of the school. Karate Junction had established its name as a quality martial arts school over the previous 20 years and the students there affectionately referred to it as KJ. As stated previously the core of the school was Soo Bahk Do.

There are very many aspects of this style that distinguishes itself from other martial arts. From a visual standpoint, one of the most noticable differences is that the style does not use a black belt to signify an advanced rank but rather midnight blue. For the founder of this style, he believed that using black was not appropriate because in most cultures black signifies death or an ending. For practitioners who have reached this rank, they view it as a new beginning to a new level. This new level culminates at a time when the practitioner tests for Master Instructor certification and the rank of fourth degree "black belt". The test is intensive lasting 16 hours a day for nine days. Upon passing this examination the practitioner receives a red stripe down the center of his/her belt.
