Knife sharpener in Kabul, Afghanistan (1961) The Knife Grinder by Massimiliano Soldani (c.1700), Albertinum, Dresden A railway camp cook sharpens a knife blade on a stone wheel, 1927. 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 ...
Many modern replica blades are not made with any distal taper, resulting in a blade that, when wielded, will feel unresponsive and heavy. Profile taper refers to narrowing upon the edges of the flat of the blade. Blades with a more gradual taper are meant for cutting, whereas blades with an acute taper are usually meant for thrusting.
The American Bladesmith Society, or ABS, is a non-profit organization composed of knifemakers whose primary function is to promote the techniques of forging steel blades.The ABS was founded by knifemaker William F. Moran, who came up with the concept in 1972 when he was Chairman of the Knifemakers' Guild; the following year, he introduced Damascus steel blades at an annual show.
The optimal angle depends upon the knife geometry, the cut speed and many other parameters. If the angle is adjusted to zero, the knife cut can often become erratic, and a new location of the knife must be used to smooth this out. If the angle is too large, the sample can crumple and the knife can induce periodic thickness variations in the cut.
A contemporary pattern-welded sword blade made by Danish swordsmith Ejvind Nørgård. The blade shows a chevron pattern with opposing twists and straight laminate alternating. Pattern welding is a practice in sword and knife making by forming a blade of several metal pieces of differing composition that are forge-welded together and twisted and ...
The shape of the blade, whether curved or straight, is a function of the carving purpose of the user: straight for whittling wood, making splints for baskets and incising, curved for hollowing out bowls and masks and ladles, as well as myriad other usages. A finely carved Crooked Knife in the form of a Bending Woman c. 1800-1825. Private ...
Negative rake: A tool has a negative rake angle when the face of the cutting tool slopes away from the cutting edge at outer side. Positive rake angles generally: Make the tool more sharp and pointed. This reduces the strength of the tool, as the small included angle in the tip may cause it to chip away. Reduce cutting forces and power ...
