Tekkis

Tekkis is a term with multiple meanings. In martial arts, tekkis refers to a set of three Shotokan karate katas collectively known as Tekki Shodan, Tekki Nidan, and Tekki Sandan. The Tekki katas are associated with the Naihanchi lineage and are typically performed in kiba-dachi (horse stance). They emphasize deep stances, hip rotation, and close-range blocking and counterattacking techniques, with sequences that move from one side to the other and require strong coordination between the hips and shoulders. The series is usually taught early in many Shotokan programs, and in some styles these forms are also known by the Naihanchi names rather than Tekki.

Separately, tekkis can be encountered as an informal plural of techie, referring to people who work in or are enthusiastic about technology. This usage is colloquial and not standardized; it appears mainly in online communities or casual speech. It is not a proper noun or a formal term in any widely recognized organization. When clarity is required, "techies" or "technology enthusiasts" is preferred.
