A garden tool with a non-slip handle grip, designed for immediate and not difficult removal of deep-rooted plants such as Thistle and Dock weeds. The body of the tool is of rigid and strong construction, with angled cutting faces and includes a plant/soil containment chamber. The tools angular cutting faces and profile, are designed to produce efficient insertion and soil compression when downward thrust is applied, which therefore holds captive the plant root in the containment chamber, hence achieving successful plant removal from the ground when the tool is withdrawn. The slotted front of the containment chamber allows for unwanted plant and soil removal from the tool. Optional hand and foot cross-members added, to produce more forceful insertion into and easier withdrawal from the ground, and to create a convenient standing operating stance, when using the tool.

1. A plant/weed extraction tool including a body, in which:(a) said body is elongated, having a first, forward, end, and a second, rearward, end, and is rigid, generally tubular, has an interior surface and an exterior surface and has a rectangular cross-section;(b) said body has a first side, a sec
1. A plant/weed extraction tool including a body, in which:(a) said body is elongated, having a first, forward, end, and a second, rearward, end, and is rigid, generally tubular, has an interior surface and an exterior surface and has a rectangular cross-section;(b) said body has a first side, a second side opposite said first side, a third side between said first side and said second side and a fourth side between said first side and said second side and opposite said third side;(c) said first side defines a longitudinal slot which extends between said first end and said second end for receiving plant/weed foliage;(d) said first end includes a first pointed projection, a second pointed projection and a third pointed projection;(e) said first pointed projection defines the forward end of said second side and projects forward of said third and fourth sides;(f) said second pointed projection and said third pointed projection are positioned one at each side of said slot and together define the forward end of said first side, said second pointed projection and said third pointed projection each project forward of said third side and said fourth side, the forwardmost point of each of said second and third pointed projection points being adjacent said slot. 2. A tool as claimed in claim 1, including a plastics or rubber cap covering the second end of said body, the cap having a plug engagable with said interior surface of said body, and said tool also including a plastics or rubber sleeve covering said cap and a section of said rearward end of said body to provide a handle portion. 3. A tool as claimed in claim 1, in which:(a) said first pointed projection has a first point and a first and a second cutting edge extending from said first point rearwards to a respective one of said second side and said third side;(b) said second pointed projection has a second point and a third cutting edge extending from said second point rearwards to said third side;(c) said third pointed projection has a third point and a fourth cutting edge extending from said third point rearwards to the fourth side;d) said third side and said fourth side each has a forward planar end face in which the edge of each end face adjacent said interior surface of the body is forward of the edge of each end face adjacent said exterior surface of the body. 4. A tool as claimed in claim 3, further comprising foot and hand cross-members. 5. A method of making a tool comprising:(a) folding a piece of sheet metal to form an elongated, generally tubular body having a rectangular cross-section, said body having a first end and a second end, a first side, a second side opposite said first side, a third side between said first and second sides and a fourth side between said first and second side and opposite said third side; and the body defining a longitudinal slot which extends between said first and second end for receiving plant/weed foliage; and(b) performing two cuts each perpendicular to said first side and at 450° to the longitudinal axis of said body at said first end of said body such that said first end includes a first pointed projection, a second pointed projection and a third pointed projection, and in which said first pointed projection defines the forward end of said second side and projects forward of said third and fourth sides and said second pointed projection and said third pointed projection are positioned one at each side of said slot and together define the forward end of said first side, both said second pointed projection and third pointed projection projecting forward of said third side and said fourth side, the forwardmost point of each of said second pointed projection and said third pointed projection being adjacent said slot.
