A dibber or dibble or dibbler is a pointed wooden stick for making holes in the ground so that seeds, seedlings or small bulbs can be planted.
In the eighteenth and nineteenth centuries, farmers would use long-handled dibbers of metal or wood to plant crops.
It was not until the Renaissance that dibbers became a manufactured item, some made of iron for penetrating harder soils and clay.
It is anything from a sharpened stick to a more complicated model incorporating a curved handle and pointed steel end.
[1] In military parlance an aircraft-dropped 'dibber bomb' is an anti-runway penetration bomb which destroys runways by first penetrating below the tarmac before exploding, cratering, and displacing the surface, making repairs difficult and time consuming, during which conventional airplanes can neither land nor take off.
