Figure 106.—Triple triangle pattern on working adzes: a , closed triple triangle (British Mus., + 1612), attributed to Rarotonga; c, overlapping triple triangle (Bishop Mus., 8040), Aitutaki. a, haft length 21.75 inches; foot length 4.25 inches, slight dorsal knob (1) on proximal end of shaft; heel with bilateral rounded projections (2), the lashing braid evidently had some fixation turns around the foot and adz butt and then made a couple of vertical turns over heel knobs, after which triple triangle pattern was developed; last vertical turn around shaft, when it reached top was passed around a crossing turn and carried on down to take part in lashing bast collar (3) to shaft; collar (3) formed of strips of hibiscus bast compressed into a roll on back and sides of shaft with free ends hanging down on either side for 94 mm., roll part being 16 mm. in diameter; the braid from adz-head lashing took some wide spirals around collar and some close transverse turns around both limbs below shaft. b, front of heel, shows lateral projection (2, 2) and crossing turns passing over them. c, haft length 15.5 inches, front height 4.25 inches. Haft has rectangular enlargement (1) on haft carved into triangle and lozenge patterns, also on shaft; pronounced heel (2) with median posterior edge and point end cut off; adz head with marked shoulder (3) typical of Aitutaki; pattern with overlapping triangle (4); last vertical turn on far side has braid end tucked in under upper horizontal turns (5); treatment of shaft is post-European.
