Sharpened metal drop-point blade Naturally occurring sharp obsidian piece Shark tooth with a sharp, serrated edge A sewing needle comes to a sharp point. 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 horizontal machine band knife blade is supported by a guide to give dimensional accuracies while cutting/splitting. Therefore, only blades that have passed as one main manufacturing step a surface grinding process reach the necessary thickness tolerances of less than 0.02 mm (0.00079 in).
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.
Knife sharpening proceeds in several stages, in order from coarsest (most destructive) to finest (most delicate). These may be referred to either by the effect or by the tool. Naming by effect, the stages are: sharpening: removing metal to form a new edge rough sharpening (using either water stones, oil stones, or medium grits of sandpaper)
The term is based on the word "whet", which means to sharpen a blade, [3] [4] not on the word "wet". The verb nowadays to describe the process of using a sharpening stone for a knife is simply to sharpen, but the older term to whet is still sometimes used, though so rare in this sense that it is no longer mentioned in, for example, the Oxford Living Dictionaries.
A rotary cutter is a tool generally used by quilters to cut fabric.It consists of a handle with a circular blade that rotates, thus the tool's name. Rotary cutter blades are very sharp, can be resharpened, and are available in different sizes: usually smaller blades are used to cut small curves, while larger blades are used to cut to straight lines and broad curves.
Razor blades, straight, or circular blades are being used. Some blades cut through the material while others crush the material against a hard roll. Those are similar to knives. The cutting blades can be set to a desired width. Some machines have many blades and can produce a number of output rolls at once.
Sanforization is a treatment for fabrics to reduce shrinkage from washing. The process was patented by Sanford Lockwood Cluett (1874–1968) in 1930. It works by stretching, shrinking, and fixing the woven cloth in both length and width before cutting and producing, to reduce the shrinkage which would otherwise occur after washing. The original ...
