A macuahuitl ([maːˈkʷawit͡ɬ]) is a weapon, a wooden sword with several embedded obsidian blades. The name is derived from the Nahuatl language and means "hand-wood". [2] Its sides are embedded with prismatic blades traditionally made from obsidian, which is capable of producing an edge sharper than high quality steel razor blades. The ...
Wazamono (Japanese: 業 （ わざ ） 物 （ もの ）) is a Japanese term that, in a literal sense, refers to an instrument that plays as it should; in the context of Japanese swords and sword collecting, wazamono denotes any sword with a sharp edge that has been tested to cut well, usually by professional sword appraisers via the art of tameshigiri (test cutting).
This process aligns the cutting edge properly with the back of the blade, avoiding "bumps" on the cutting edge. Rotating the blade on the strop about the cutting edge can damage it because such use will impact the micro-alignment of the edge. [50] Depending on use and condition, the blade can be sharpened occasionally by using a razor hone.

Sharpness refers to the ability of a blade, point, or cutting implement to cut through materials with minimal force, and can more specifically be defined as the capacity of a surface to initiate the cut.

The angle between the blade and the stone is the edge angle – the angle from the vertical to one of the knife edges, and equals the angle at which the blade is held. The total angle from one side to the other is called the included angle – on a symmetric double-ground edge (a wedge shape), the angle from one edge to the other is thus twice ...
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.
The razor and blade model is a classic business strategy: Give away the razor, and the consumer will have to purchase the associated blades. For a while, Microsoft has been the default blade for PCs.
