Gränsfors Splitting Axes are, as the name suggests, made to split wood. The axes have a large and heavy head that is forged and ground into a concave shape with a relatively thin edge. The axes are made to chop along the grain of the wood fibres, in contrast to Forest Axes, which are made to cut across the grain of the wood fibres.
The concave shape of the Splitting Axes ensures that the edge goes quickly and easily into the wood and then effectively splits it as the broader section pushes apart the wood. Its unique design also means that the axe head does not stick as easily in the wood, as would happen with a slimmer axe head.
