Common handmade leather making tools introduced

A cut leather tool cut In fact, ordinary paper knife can be, but to be a tradesman, the use of tools to enjoy time can not be ignored. I have four skin cutters, the earliest learning to do leather, with the Ariva blade for cutting edge knife, flat Japanese knives, blades can be replaced without sharpening; and later in a circle very influential There is a custom made a half-moon shape, blade material is industrial cutting blade plate; and then start the show times the first pole on the bipolar knife, the lack of resources in Japan, so even if the pole is such a level pole knife is also used steel Craft, only the blade part is steel, the blade is iron; this month I started a knife, using the best material known as the skin cutting knife - Swedish powder Damascus steel, the steel is Sweden win 100 The company developed the tool-specific steel, together with the mahogany shank, slant polished, regarded as the most cutting-edge tool in my leather cut. Rui Damascus, beautiful pattern, right? Pattern is forged in the process of folding and forging formed by repeated, not later engraving. From left to right: Ariva for the blade, half-moon knife, show times Bi pole, Rui Fen big town, the role of the equivalent of the town of paper figures, the letter of the seal, used to knock the number above the leather, the letter spacing gauge black is the rotation Cutter, wood cross is a belt cutter Left: American thinner, in: Mijing Square arc plane, right: American thinner, horizontal grip. Are used to thin leather fillet knife, used to cut leather corner so that the transition to a circular arc

Nylon is a generic designation for a family of synthetic polymers, based on aliphatic or semi-aromatic polyamides. Nylon is a thermoplastic silky material[1] that can be melt-processed into fibers, films, or shapes.[2]:2 It is made of repeating units linked by amide links[3] similar to the peptide bonds in proteins. Nylon polymers can be mixed with a wide variety of additives to achieve many different property variations. Nylon polymers have found significant commercial applications in fabric and fibers (apparel, flooring and rubber reinforcement), in shapes (molded parts for cars, electrical equipment, etc.), and in films (mostly for food packaging).[4]

Nylon was the first commercially successful synthetic thermoplastic polymer.[5] DuPont began its research project in 1927.[6] The first example of nylon (nylon 6,6) using diamines on February 28, 1935, by Wallace Hume Carothers at DuPont's research facility at the DuPont Experimental Station.[7][8] In response to Carothers' work, Paul Schlack at IG Farben developed nylon 6, a different molecule based on caprolactam, on January 29, 1938.[9]:10[10]

Nylon was first used commercially in a nylon-bristled toothbrush in 1938,[11][12] followed more famously in women's stockings or "nylons" which were shown at the 1939 New York World's Fair and first sold commercially in 1940.[13] During World War II, almost all nylon production was diverted to the military for use in parachutes and parachute cord. Wartime uses of nylon and other plastics greatly increased the market for the new materials.[14]
