Blade geometry is a crucial aspect of knife design, influencing both the performance and usability of cutting tools. ... Weapons such as the Estoc, for example, would ...
Knife sharpening is the process of making a knife or similar tool sharp by grinding against a hard, rough surface, typically a stone, [1] or a flexible surface with hard particles, such as sandpaper. Additionally, a leather razor strop, or strop, is often used to straighten and polish an edge. The trade or occupation is called knifegrinder or ...
A trailing-point knife has a back edge that curves upward to end above the spine. This lets a lightweight knife have a larger curve on its edge and indeed the whole of the knife may be curved. Such a knife is optimized for slicing or slashing. Trailing point blades provide a larger cutting area, or belly, and are common on skinning knives.
A hand-held tungsten carbide knife sharpener, with a finger guard, can be used for sharpening plain and serrated edges on pocket knives and multi-tools.. Sharpening is the process of creating or refining a blade, the edge joining two non-coplanar faces into a converging apex, thereby creating an edge of appropriate shape on a tool or implement designed for cutting.
The knife-edge effect or knife-edge diffraction is a truncation of a portion of the incident radiation that strikes a sharp well-defined obstacle, such as a mountain range or the wall of a building. The knife-edge effect is explained by the Huygens–Fresnel principle , which states that a well-defined obstruction to an electromagnetic wave ...
Since beams typically do not have sharp edges, the diameter can be defined in many different ways. Five definitions of the beam width are in common use: D4σ, 10/90 or 20/80 knife-edge, 1/e 2, FWHM, and D86. The beam width can be measured in units of length at a particular plane perpendicular to the beam axis, but it can also refer to the ...
Knife Edge, Knife-edge, or Knife's Edge may refer to: Knife Edge, a 2009 British thriller about gaslighting "Knife-Edge" (Emerson, Lake & Palmer song) Knife Edge: Nose Gunner, a video game; Young Sherlock Holmes: Knife Edge, a 2003 book in the Young Sherlock Holmes book series; Standing Figure: Knife Edge, a bronze sculpture by Henry Moore
A Bowie knife clearly showing the clip point. The clip point is one of the three most common shapes for the blade of a knife (the others being the drop point and the spear point). Clip point blades have the appearance of having the forward third of the blade "clipped" off. The clip itself can be straight or concave. [1] [2]
