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.
When splitting wood, the handle is put under great strain at the axe head, as the handle can easily hit the log being split. All Gränsfors Splitting Axes therefore come with a metal collar to protect the handle. The handle is also grooved towards the end for an extra firm grip.
The Gränsfors Splitting Axes come in four sizes: the Splitting Hatchet, the Small Splitting Axe, the Large Splitting Axe and the Splitting Maul. There is also a Splitting Wedge for use with the Splitting Maul. The three smaller axes are all similar in design, differing only in the weight of the head and the length of the handle. The head of the Splitting Maul has a different shape, with a rather longer and heavier poll with bevelled corners.
