Figure 55. Adz haft, with simple mesial peg. a, side view: rounded branch shaft (1) meets trunk foot (2) with heel (3) above and toe (4) below; upper line of shaft runs straight to heel without forming heel angle, toe angle (5) formed below; toe cut to deeper level at shoulder (6) to form adz surface (7); mesial peg (8) in position; diameter of shaft, 1 inch; depth of foot, 4.6 inches; depth of adz surface, 2.2 inches; foot, 0.7 inch thick at lower end. b, front of foot: transverse shoulder (6) defines upper limits of flat adz surface (7) which is 1.4 inches wide below and 1.5 inches above; foot cut away in mesial line above shoulder to fit mesial peg which is 3.7 inches long and about 0.3 inch thick, and corresponds in depth to shoulder; peg, 0.6 inch wide at bottom, narrows gradually to 0.4 inch at point 9, widens out again to 0.6 inch, gradually diminshes to 0.35 inch, and projects above toe for 1.3 inches; peg thus doubly wedge-shaped to prevent upward displacement from pressure of adz poll when in use.
