The list of Case knife patterns has remained fairly consistent throughout its history, although a number of new Case designs have been patented in recent years. Some of these include: The SlimLock, Trapper, Tiny Trapper, Baby Doc, Tribal-Lock, CopperLock, RussLock, Baby Butterbean, Cheetah, Cheetah Cub, Hobo, Sod Buster, Mako, Mini-Blackhorn ...
Case-hardening or carburization is the process of introducing carbon to the surface of a low-carbon iron, or more commonly a low-carbon steel object, in order to harden the surface. Iron which has a carbon content greater than ~0.02% is known as steel .
RHA is homogeneous because its structure and composition are uniform throughout its thickness. The opposite of homogeneous steel plate is cemented or face-hardened steel plate, where the face of the steel is composed differently from the substrate. The face of the steel, which starts as an RHA plate, is hardened by a heat-treatment process.
The karambit or kerambit (as used in Indonesian), kurambik or karambiak (both from the Minangkabau language) is a small curved knife resembling a claw. It is most closely associated with the Minangkabau people of West Sumatra , Indonesia , but is also found throughout other ethnic groups in Southeast Asia .
Quench polish quench (QPQ) is a specialized type of nitrocarburizing case hardening that increases corrosion resistance. It is sometimes known by the brand name of Tufftride, Tenifer or Melonite. [1] Three steps are involved: nitrocarburize ("quench"), polish, and post-oxidize ("quench"). [2]
Very hard steel (e.g. chisels, quality knife blades): HRC 55–66 (Hardened High Speed Carbon and Tool Steels such as M2, W2, O1, CPM-M4, and D2, as well as many of the newer powder metallurgy Stainless Steels such as CPM-S30V, CPM-154, ZDP-189. There are alloys that hold a HRC upwards 68-70, such as the Hitachi developed HAP72.
This also inversely affects the depth of the case; i.e., a high carbon steel will form a hard, but shallow case. [14] A similar process is the trademarked "Nu-Tride" process, also known incorrectly as the "Kolene" process (which is the company's name), includes a preheat and an intermediate quench cycle.
The origin of the name "Damascus Steel" is contentious. Islamic scholars al-Kindi (full name Abu Ya'qub ibn Ishaq al-Kindi, circa 800 CE – 873 CE) and al-Biruni (full name Abu al-Rayhan Muhammad ibn Ahmad al-Biruni, circa 973 CE – 1048 CE) both wrote about swords and steel made for swords, based on their surface appearance, geographical location of production or forging, or the name of the ...
