Knife indentation is done away from the edge of a kitchen knife. A knife most simply has either a rectangular or wedge-shaped cross-section (sabre-grind v. flat-grind, but may also have concave indentations or hollows, whose purpose is to reduce adhesion of the food to the blade, so producing a cleaner and easier cut. This is widely found in ...
In mechanical engineering and materials science, a notch refers to a V-shaped, U-shaped, or semi-circular defect deliberately introduced into a planar material. In structural components, a notch causes a stress concentration which can result in the initiation and growth of fatigue cracks.
A chevron (also spelled cheveron, especially in older documents) is a V-shaped mark or symbol, often inverted.The word is usually used in reference to a kind of fret in architecture, or to a badge or insignia used in military or police uniforms to indicate rank or length of service, or in heraldry and the designs of flags (see flag terminology).
Loop-holes were frequent in Italian battlements, where the merlon has much greater height and a distinctive cap. Italian military architects used the so-called Ghibelline or swallowtail battlement, with V-shaped notches in the tops of the merlon, giving a horn-like effect. This would allow the defender to be protected whilst shooting standing ...
Gulch – Deep V-shaped valley formed by erosion; Gully – Landform created by running water and/or mass movement eroding sharply into soil; Hogback – Long, narrow ridge; Hoodoo – Tall, thin spire of relatively soft rock usually topped by harder rock; Homoclinal ridge – Ridge with a moderate sloping backslope and steeper frontslope
V-joint This type of joint can be made with a V-shaped jointer or a trowel soon after the bricks are laid. Ornamental and highly visible, the joint conceals small irregularities and is highly attractive. Like the concave joint, the V-joint is water-resistant because its formation compacts the mortar and its shape directs water away from the seal.
In manufacturing or mechanical engineering a groove is a long and narrow indentation built into a material, generally for the purpose of allowing another material or part to move within the groove and be guided by it. Examples include: A canal cut in a hard material, usually metal.
Diagonal burr pieces are square sticks with V-shaped notches, cut at an angle of 45° off the stick's face. These puzzles are often called "stars", as it is customary to also cut the sticks' edges at an angle of 45°, for aesthetic reasons, giving the assembled puzzle a star -like shape.
