My lineage Kwan's name, Song Moo Kwan, is an almost literal translation of Shoto Kan: the later, incorporating Funakoshi's nom de plume `Shoto', waving pines, translates as Waving Pine Tree Hall (or House); the former is Korean for Pine Tree Hall of Martial Training. Byung Jik Ro was first and foremost a Shotokan devotee (
fourth dan under Gichin Funakoshi) , and it shows; SMK emphasizes hand and elbow techs and low-to-midbody kicks, with pins and locks designed to set up strikes.
This last point is relevant: Shotokan preserves, even in somewhat attentuated form, the Tuite elements of its Okinawan sources that used controlling moves, including throws, not along the Judo/Aikido strategic line of using joint stress to defeat the assailant, but rather as a tactical means to force the attacker into a position where a high-value target—typically the head and neck—were brought within range of a knifehand strike to the throat, a hammerfist to the temples, an elbow strike to the middle of the face, and so on. And SMK, faithful as it is to its Shotokan parent, incorporates the same joint control elements. We were taught to use the upward `chambering' part of a down `block' as a forcible pivot point against the assailant's elbow (just above, actually) when the latter's arm was fully extended by a `chambering retraction' of the other fist (which is, in fact, holding onto the assailant's trapped wrist after an agressive grip has been reversed). A `front stance' projecting the defender's full body weight into the pin, and down (the `low' part of the `low stance') forces the attacker's head down, and the followup down `block' is thus a hammer fist to the attacker's temple, carotid sinus, jaw, or a range of weak points below the necks (a collarbone break, e.g.) or the upper arm.
From what I've been able to find out, SMK was the most literally Shotokan of all the Kwan styles; even our approach to hyungs is harder, more abrupt and rhythmically varied than what I've seen of hyung performance in other Kwan styles, but very much along the lines of Shotokan kata performance. I'm sure there's more to the story, though... there always is!
