  Backfist - Knuckle strikes (등주먹, Deungjumeok)

  Korean 등주먹치기 (Deungjumeok Chigi): the fist is closed exactly as for a forward punch — only the wrist orientation changes so that the dorsal surface of the second-row knuckles is the impact face. The previous values left the fist noticeably loose (1.4 / 1.4 / 0.7), which is biomechanically inconsistent with a 등주먹 strike where the fist must be a single rigid mass on impact. Now matches FIST tightness.

  Closed Fist - Standard punch (주먹) Fingers curled tight, thumb wrapped outside over index/middle PIPs.

  Korean martial arts (Taekwondo / Tang Soo Do / Hapkido) fist:

  • MCP (prox) flexed ~90° (1.57 rad)
  • PIP (inter) flexed ~90° (1.57 rad)
  • DIP (dist) flexed ~63° (1.1 rad) — fingertips pressed firmly into the distal palmar crease so the striking surface is the front of the second-row knuckles (정권). Previous value of 0.8 rad (~46°) left the fingertips visibly slack and reduced impact-surface integrity.

  Hammer Fist - Bottom fist strikes (철퇴, Cheoltoe)

  Korean martial arts hammer-fist (망치주먹): the fist is clenched tighter than a standard punching fist because the striking surface is the bottom (ulnar-side) of the rolled fingers, which must be a hard, compact mass with no give. PIP/MCP are at the upper end of voluntary flexion (~97° / 1.7 rad) and DIP is now ~69° (1.2 rad) so the fingertips bury deep into the palmar crease and present a single, rounded striking ridge along the pinky side.

  Knife Hand - Ridge hand strikes (수도, Sudo)

  Korean 수도치기 (Sudo Chigi): all four fingers fully extended and pressed tightly together so the medial edge of the hand (pinky-side fascia overlying the fifth metacarpal) forms a rigid striking ridge. The thumb is firmly adducted and flexed across the palm so it cannot be hooked or broken by the target.

  Previous values held the fingers at a slight 0.1 rad bend, which softens the ridge and is anatomically incorrect for 수도. Fingers are now strictly 0 rad (fully straight); thumb wrap is unchanged.
