Tipatshimuna 
Description:
A wooden maul, made from a length of white spruce trunk. The bark remains on about 50% of the surface. About halfway down its length it starts tapering into a handle, which appears to have been shaped with an axe. The thicker, hitting end has a small wedge cut from its underside in order to create a small relatively flat surface for hammering. The wood is split and splintered near the centre of the hammering surface, and on the sides of the maul nearest to that point. Some of the bark has white/grey lichen colonies on it.

This wedge was made and used by Pien Penashue in August 2002 during the Labrador Innu Canoe Project. The wedge was used to split timber from white spruce trees (minaiku) that could be fashioned into planks and ribs for a canoe. Having selected suitable trees, namely those with straight grains and no knots in the lower 2-3 metres of trunk, Pien and his apprentices (Melvin Penashue and Alistair Pone), felled the trees using a chainsaw. The trees were then split open using an axe, wooden wedges, and a mallet (maul). The trees were first quartered, then split into eighths. The axe was then used to split these smaller pieces into thin planking, with the blade of the axe placed parallel to the outer bark of the tree. Peter Armitage diary notes re. canoe making, 2002
In his chapter about building a birch bark canoe, Rick Nash includes a photo that shows clearly the use of a wedge to split wood for ribs and planking. “The top end of the tree was opened up first with an axe, and then with wedges. It was split evenly in half, then into quarters, then sixteenths.” – (2002:59)
“Before steel tools became available to the Indians, the woodwork required in constructing a birch-bark canoe represented great labor, since stone tools having poor cutting characteristics were used. Selection of the proper wood was therefore a vital consideration. In most sections of the bark canoe area, the northern white cedar [spruce] was the most sought-for wood for canoe construction. This timber had the excellent characteristic of splitting cleanly and readily when dry and well-seasoned… If split properly, ribs of white cedar could be bent and set in shape by the use of hot water.” Edwin Adney and Howard Chapelle (1964:16-17)
“Splitting was done by starting the split at the upper, or small end, of a balk of timber with a maul and a stone wedge or the blade of a stone axe, hatchet, or knife… The tool was usually driven into the wood with blows from a wooden club or maul, the brittle stone tool being protected from damage by a pad of rawhide secured to the top, or head, of the tool. Once the split was started, it could be continued until the whole balk was divided. White cedar was split into quarters by this method and then the heartwood was split away, the latter being used for canoe structural members.” Edwin Adney and Howard Chapelle (1964:18)
“The pieces of wood to be used for the ribs, crosspieces, and sheathing were split with a stone wedge or with the edge of a knife or a hatchet. The blades were started into the wood by hitting them with a wooden maul. When a split was started, more wedges were driven in along the split until the wood was completely divided. Commonly the wood was first quartered and then each quarter split into smaller pieces. In white cedar [spruce], the splits were made parallel to the bark side, as this wood bends well only toward or away from the outer or bark side.” George Fichter (1977:18-19)
