A froe (or frow), shake axe or paling knife is a tool for cleaving wood by splitting it along the grain. It is an L-shaped tool, used by hammering one edge of its blade into the end of a piece of wood in the direction of the grain, then twisting the blade in the wood by rotating the haft (handle).
A froe uses the haft as a lever to multiply the force upon the blade, allowing wood to be torn apart with remarkably little force applied to the haft. By twisting one way or the other the direction of the split may be guided. [1]
Froes are used in combination with mallets to split timber, to make planks, wooden shingles, or kindling; they are safer and more accurate to use than hatchets or splitting mauls because the blade is not swung.
The origin of the word froe is not clear, and some references find it spelled frow. One possibility of its roots can be found in the Old English word fro, which meant "away" (as in the phrase "to and fro"), which was the direction one hammered the froe to split the wood. [2]
Froes are similar in general form to axes, in that a froe is an L-shaped assembly of a blade head (typically steel) set at a right angle to a handle called a haft (traditionally wood). A froe can be thought of as an axe which is sharpened along the top of a long, narrow, rectangular head, instead of (as the axe is) at the end of a broad curved head. Some froes are made of a single piece of metal with no perpendicular haft. Instead, the handle is the unbeveled end of the blade which extends directly from the blade. These froes must be hammered through the entire piece of wood, as their lack of vertical haft makes it extremely difficult to lever the wood apart. [3] A given froe can split a piece of wood no wider in its narrowest dimension than the length of the froe's blade; that is, when you place the froe, it must cross the surface of the wood completely.
A froe is also unlike an axe or maul in that the froe can be placed exactly where the user would like the split to begin. With the exception of users with expert aim, axes and mauls cannot. This technique can be used with enough precision that regularity of measurements can be kept when cutting shingles, ground stakes, or even small rails or planks. Another use is to rive pieces of wood to be used for steam bending, as this wood follows the grain and is less prone to breakage.
Hitting the narrow blade of a froe repeatedly soon damages a mallet, and so the traditional implement used to hit it is a froe club. This is simply a short length of a thin log, still with the bark on it, with one end reduced with a drawknife to convenient diameter for a handle. It is rotated slightly in the hand with each blow so as to even the wear and, although the club soon wears out, a new one can easily be made.
A hammer is a tool, most often a hand tool, consisting of a weighted "head" fixed to a long handle that is swung to deliver an impact to a small area of an object. This can be, for example, to drive nails into wood, to shape metal, or to crush rock. Hammers are used for a wide range of driving, shaping, breaking and non-destructive striking applications. Traditional disciplines include carpentry, blacksmithing, warfare, and percussive musicianship.
A chisel is a tool with a characteristically shaped cutting edge of blade on its end, for carving or cutting a hard material such as wood, stone, or metal by hand, struck with a mallet, or mechanical power. The handle and blade of some types of chisel are made of metal or of wood with a sharp edge in it.
In archaeology, a hammerstone is a hard cobble used to strike off lithic flakes from a lump of tool stone during the process of lithic reduction. The hammerstone is a rather universal stone tool which appeared early in most regions of the world including Europe, India and North America. This technology was of major importance to prehistoric cultures before the age of metalworking.
A splitting maul also known as a block buster, block splitter, chop and maul, sledge axe, go-devil or hamaxe is a heavy, long-handled axe used for splitting a piece of wood along its grain. One side of its head is like a sledgehammer, and the other side is like an axe.
A hand plane is a tool for shaping wood using muscle power to force the cutting blade over the wood surface. Some rotary power planers are motorized power tools used for the same types of larger tasks, but are unsuitable for fine-scale planing, where a miniature hand plane is used.
A sledgehammer is a tool with a large, flat, often metal head, attached to a long handle. The long handle combined with a heavy head allows the sledgehammer to gather momentum during a swing and apply a large force compared to hammers designed to drive nails. Along with the mallet, it shares the ability to distribute force over a wide area. This is in contrast to other types of hammers, which concentrate force in a relatively small area.
A battle axe is an axe specifically designed for combat. Battle axes were specialized versions of utility axes. Many were suitable for use in one hand, while others were larger and were deployed two-handed.
A drawknife is a traditional woodworking hand tool used to shape wood by removing shavings. It consists of a blade with a handle at each end. The blade is much longer than it is deep. It is pulled or "drawn" toward the user.
A wedge is a triangular shaped tool, and is a portable inclined plane, and one of the six simple machines. It can be used to separate two objects or portions of an object, lift up an object, or hold an object in place. It functions by converting a force applied to its blunt end into forces perpendicular (normal) to its inclined surfaces. The mechanical advantage of a wedge is given by the ratio of the length of its slope to its width. Although a short wedge with a wide angle may do a job faster, it requires more force than a long wedge with a narrow angle.
Wood shingles are thin, tapered pieces of wood primarily used to cover roofs and walls of buildings to protect them from the weather. Historically shingles, also known as shakes, were split from straight grained, knot free bolts of wood. Today shingles are mostly made by being cut which distinguishes them from shakes, which are made by being split out of a bolt.

Hafting is a process by which an artifact, often bone, stone, or metal is attached to a haft. This makes the artifact more useful by allowing it to be shot (arrow), thrown by hand (spear), or used with more effective leverage (axe). When constructed properly, hafting can tremendously improve a weapon's damage and range. It is estimated that hafted weapons were most common during the Upper Paleolithic and Middle Paleolithic. It was one of the first tools where hominins took separate elements and united them into a single tool. The development of hafting is considered by archaeologists to have been a significant milestone. It was not only an improvement in the technology at the time; it also showed the progression of the human mind toward a world of complex tool-making.
A flint axe was a Flint tool used during prehistoric times to perform a variety of tasks. These were at first just a cut piece of flint stone used as a hand axe but later wooden handles were attached to these axe heads. The stone exhibits a glass-like fracture similar to obsidian, and can be knapped to form large blades. The offcuts were sharp enough to be used a small flint knives, while the larger parts of a knapped nodule could be polished to form an axe-head. They competed with other hard rocks such as greenstone, which were produced at Langdale in the British Lake District and got larger as working continued. They tend to be larger and heavier than the simple axes, and are sometimes known as axe-hammers.
An axe is an implement that has been used for millennia to shape, split and cut wood, to harvest timber, as a weapon, and as a ceremonial or heraldic symbol. The axe has many forms and specialised uses but generally consists of an axe head with a handle, also called a haft or a helve.
A twybil is a hand tool used for green woodworking. It is used for chopping out mortises when timber framing, or making smaller pieces such as gates. It combines chopping and levering functions in a single tool.
A cleaving axe or cleaver is a form of axe used within green woodworking to split wood lengthways. Cleaving (riving) is used to turn a log into lumber or billets into firewood. Splitting axe is sometimes described as an old name for a splitting maul or froe.
Hacking or side knives may be considered as either light hatchets or heavyweight knives.
Batoning is the technique of cutting or splitting wood by using a baton-sized stick or mallet to repeatedly strike the spine of a sturdy knife, chisel or blade in order to drive it through wood, similar to how a froe is used. The batoning method can be used to make kindling or desired forms such as boards, slats or notches. The practice is most useful for obtaining dry wood from the inside of logs for the purpose of fire making.
Wood splitting is an ancient technique used in carpentry to make lumber for making wooden objects, some basket weaving, and to make firewood. Unlike wood sawing, the wood is split along the grain using tools such as a hammer and wedges, splitting maul, cleaving axe, side knife, or froe.
