This is a list of notable types of weapons which saw use in warfare, and more broadly in combat, prior to the advent of the early modern period, i.e., approximately prior to the start of the 16th century.
This is a list of weapons used by belligerents in the Korean War (1950–1953). Personal weapons ... Browning Hi-Power [citation needed] Walther PP [citation ...
A 5-degree shear angle decreases the force by about 20% [citation needed]. The amount of energy used is still the same. The moving blade may also be inclined 0.5 to 2.5°, called the rake angle, to keep the material from becoming wedged between the blades. However, raking the blade compromises the squareness of the edge. [4] The machine ...
The blade is made of non-rustproof carbon steel, blue-plastered by hand and finely forged from the base to the tip of the knife. The 90 mm (3.5 in) long blade shows patina (dark spots) caused by decades of use. It can easily be sharpened to a shaving sharp edge. Carbon steel is a popular choice for rough-use knives and cheaper options.
Blade shears are similar to scissors, and although most have the hinge at the back of the shears rather than the center, some still have the hinge in the center, e.g. Jakoti shears. More recent design improvements using a acetal bearing system fitted with superior wear resistant tool steel blades has greatly increased the longevity of the shears.
The blades found in shin guntō ranged from modern machine-made blades through contemporary traditionally-manufactured blades to ancestral blades dating back hundreds of years. After the Second World War's conclusion, most produced guntō were made to resemble the traditionally cloth wrapped shin-gunto swords, but out of a solid metal casting.
Shearing, also known as die cutting, [1] is a process that cuts stock without the formation of chips or the use of burning or melting. Strictly speaking, if the cutting blades are straight the process is called shearing; if the cutting blades are curved then they are shearing-type operations. [2]
Thus, it entered the shear-manufacturing business. [14] Views of the shop floor, 1946. The company was unable to obtain castings for the shears due to the fact that all the foundries were backlogged with orders, just as the machine tool manufacturers were. So, the Parker Shears were built entirely out of steel plate – no castings at all.
