A post hole clam-shell digger, also called post hole pincer or simply post hole digger, is a tool consisting of two articulated shovel-like blades, forming an incomplete hollow cylinder about a foot long and a few inches wide, with two long handles that can put the blades in an "open" (parallel) position or a "closed" (convergent) position.
The tool is used to dig holes in the ground, typically from a few inches to a about a foot in diameter, for general purposes such as setting fence and sign posts or planting saplings. In operation, the tool is jabbed into the ground with the blades in the open position. The handles are then operated to close the blades, thus grabbing the portion of soil between them. The tool is then pulled out and the soil is deposited by the side. The process is repeated until the hole is deep enough. Sometimes dry or sandier soils will not stay secured in the clams.
An earth auger is another tool that is used to dig holes in the ground, consisting of a rotating shaft with one or more blades attached at the lower end. A hand-powered auger is generally easier to use than a clam-shell digger, and can in principle dig deeper and remove more dry, sandy soils. It naturally creates a round and straight hole, but only of a fixed diameter. The shovel like shape of a clam-shell-type digger allows it to be used to dig holes of any shape and any diameter greater than that of the open blades.
Clam-shell-type pole diggers seem to be a relatively recent invention, newer than earth augers. A patent was filed by J. Lawry of Lenior City, Tennessee in 1908. [1] The patent has the traditional clam-shell design with an extra spike in the center.[ citation needed ]
A plough or plow is a farm tool for loosening or turning the soil before sowing seed or planting. Ploughs were traditionally drawn by oxen and horses but in modern farms are drawn by tractors. A plough may have a wooden, iron or steel frame with a blade attached to cut and loosen the soil. It has been fundamental to farming for most of history. The earliest ploughs had no wheels; such a plough was known to the Romans as an aratrum. Celtic peoples first came to use wheeled ploughs in the Roman era.
The router is a power tool with a flat base and a rotating blade extending past the base. The spindle may be driven by an electric motor or by a pneumatic motor. It routs an area in hard material, such as wood or plastic. Routers are used most often in woodworking, especially cabinetry. They may be handheld or affixed to router tables. Some woodworkers consider the router one of the most versatile power tools.
A drill is a tool used for making round holes or driving fasteners. It is fitted with a bit, either a drill or driverchuck. Hand-operated types are dramatically decreasing in popularity and cordless battery-powered ones proliferating due to increased efficiency and ease of use.
A spade is a tool primarily for digging consisting of a long handle and blade, typically with the blade narrower and flatter than the common shovel. Early spades were made of riven wood or of animal bones. After the art of metalworking was developed, spades were made with sharper tips of metal. Before the introduction of metal spades manual labor was less efficient at moving earth, with picks being required to break up the soil in addition to a spade for moving the dirt. With a metal tip, a spade can both break and move the earth in most situations, increasing efficiency. A classic spade, with a narrow body and flat tip is suited for digging post holes, and is not to be confused with a "roundpoint" shovel, which has a wider body and tapered tip.
A hoe is an ancient and versatile agricultural and horticultural hand tool used to shape soil, remove weeds, clear soil, and harvest root crops. Shaping the soil includes piling soil around the base of plants (hilling), digging narrow furrows (drills) and shallow trenches for planting seeds or bulbs. Weeding with a hoe includes agitating the surface of the soil or cutting foliage from roots, and clearing the soil of old roots and crop residues. Hoes for digging and moving soil are used to harvest root crops such as potatoes.
Drill bits are cutting tools used in a drill to remove material to create holes, almost always of circular cross-section. Drill bits come in many sizes and shapes and can create different kinds of holes in many different materials. In order to create holes drill bits are usually attached to a drill, which powers them to cut through the workpiece, typically by rotation. The drill will grasp the upper end of a bit called the shank in the chuck.
A trowel is a small hand tool used for digging, applying, smoothing, or moving small amounts of viscous or particulate material. Common varieties include the masonry trowel, garden trowel, and float trowel.
A digging stick, sometimes called a yam stick, is a wooden implement used primarily by subsistence-based cultures to dig out underground food such as roots and tubers, tilling the soil, or burrowing animals and anthills. It is a term used in archaeology and anthropology to describe similar implements, which usually consists of little more than a sturdy stick which has been shaped or sharpened and sometimes hardened by being placed temporarily in a fire.
A snow blower or snow thrower is a machine for removing snow from an area where it is problematic, such as a driveway, sidewalk, roadway, railroad track, ice rink, or runway. The commonly used term "snow blower" is a misnomer, as the snow is moved using an auger or impeller instead of being blown. It can use either electric power, or a gasoline or diesel engine to throw snow to another location or into a truck to be hauled away. This is in contrast with the action of snow plows, which push snow to the front or side. Typically, the snow is discharged to one side.
Clam digging is a North American term for a common way to harvest clams from below the surface of the tidal sand flats or mud flats where they live. It is done both recreationally and commercially. Commercial digging in the U.S. and Canada is colloquially referred to as clamming, and is done by a clammer.
The Atlantic jackknife clam, Ensis leei, also known as the bamboo clam, American jackknife clam or razor clam, is a large edible marine bivalve mollusc found on the North American Atlantic coast, from Canada to South Carolina. The species has also been introduced to Europe. The name "razor clam" is also used to refer to different species such as the Pacific razor clam or Razor shell.
A digging bar is a long, straight metal bar used for various purposes, including as a post hole digger, to break up or loosen hard or compacted materials such as soil, rock, concrete and ice or as a lever to move objects. Known by other names depending on locale, structural features and intended purpose such as a hop bar or crowbar in Britain, Australia and New Zealand, and slate bar, shale bar, spud bar, pinch point bar or San Angelo bar in North America, or just a bar. In Hawaii, a similar, traditional wooden device known as an ‘o‘o stick is used as a digging bar in groundbreaking ceremonies. Not to be confused with a curved crowbar, which is designed to provide leverage rather than to dig.
The MacAdam Shield-Shovel, also known as the Hughes Shovel, was an item of Canadian infantry equipment during the First World War. It was designed and patented by Sam Hughes, the Canadian minister for the Department of Militia and Defence in 1913, combining function as a shovel and as a shield. Ena MacAdam, Hughes' personal secretary, had first suggested the idea of a shield shovel to Hughes after she witnessed Swiss soldiers making field entrenchments during field exercises.
The razor shell, Ensis magnus, also called razor clam, razor fish or spoot (colloquially), is a bivalve of the family Pharidae. It is found on sandy beaches in Canada and northern Europe.
Underground pneumatic piercing tools are often referred to as a hog, air hog, or pneuma gopher. The tool is used to bore a hole underground between two points without disturbing the surface ground. This open-air chamber is referred to as the borehole and is used to either run ducting for the product or the raw product itself between the two points.
A carpenters boring machine is a hand-driven machine to bore holes in beams such in the process of making a mortise or making holes for the wooden pegs which hold mortise and tenon joints together.
Digging, also referred to as excavation, is the process of using some implement such as claws, hands, manual tools or heavy equipment, to remove material from a solid surface, usually soil, sand or rock on the surface of Earth. Digging is actually the combination of two processes, the first being the breaking or cutting of the surface, and the second being the removal and relocation of the material found there. In a simple digging situation, this may be accomplished in a single motion, with the digging implement being used to break the surface and immediately fling the material away from the hole or other structure being dug.
Homi, also known as a Korean hand plow, is a short-handled traditional farming tool used by Koreans. It is a farming tool that removes grasses from paddies and fields. It is also used when plowing a rice field, planting seeds, plowing up soil, and digging potatoes in fields. It is a farming tool similar to the hoe. It is an important extension of agriculture from the ancient times because the homi was excavated in the Bronze Age historic site of the Pyeongnam Mangsan Daepyeong-ri and the early Iron Age historic site of Yangpyong, Gyeonggi Province.
An earth auger, earth drill, or post-hole auger is a drilling tool or machine used for making holes in the ground. It typically consists of a rotating vertical metal rod or pipe with one or more blades attached at the lower end, that cut or scrape the soil.
