Abstract

The invention discloses a preparation method of a blade special for cigar scissors or cigar knives and the blade. The blade is made of hard alloy or metal ceramic; when the blade is made of hard alloy, the thickness of the blade is larger than or equal to 0.5 mm and smaller than or equal to 0.8 mm or larger than 0.8 mm and smaller than or equal to 1.5 mm. When the blade is made of metal ceramic, the thickness of the blade is larger than or equal to 0.5 mm and smaller than or equal to 1 mm or larger than 1 mm and smaller than or equal to 1.5 mm. The special blade for the cigar scissors or the cigar knife has the advantages that the surface smoothness of a grinding surface is high, the strength, the hardness, the wear resistance and the toughness are excellent, and enough cutting edge sharpness can be kept while high-fiber tobacco shreds are cut; the surface of the notch is smooth, so that the service life, the attractiveness and the use satisfaction degree of a user of the cigar knife or the cigar scissors can be remarkably improved.

Description

technical field [0001] The invention relates to the field of knife preparation, in particular to a method for preparing a special blade for cigar scissors or cigar cutters and the blade. Background technique [0002] As an important part of the current tobacco consumption, cigars are made of dried and fermented tobacco. They have the characteristics of high price, large diameter and long length of a single cigar, and high plant fiber content in tobacco leaf veins. Users It is often not possible to smoke the whole stick in a single puff, so after each puff, it is often necessary to use a professional cigar cutter or cigar to cut off the cigar head. Its appearance design, materials and accessories have been paid attention to, making it more beautiful and tasteful, and can better demonstrate the taste of cigars. Similarly, the price of cigar knives or cigar cutters is also expensive. [0003] At present, most of the common cigar cutters or cigar scissors on the market are made...
