The Delta Dart is 8 inches long and a half inch in diameter, yet it weighs only seven tenths of an ounce! The comfortable handle is knurled for a positive grip.
With the Delta Dart, you have a super-light, full sized knife that you can really get a grip on and can generate tremendous penetration. The Delta Dart can be taped, tied or tucked away just about anywhere.
Made from Grivory, the latest in fiberglass reinforced plastic, and stronger than even the super tough Zytel. UV and heat stabilized, making it impervious to the elements. The handle material is deeply checkered Kraton, that has been molded directly to the blade tang. This knife is light enough to be tied, tucked, or taped just about anywhere on ones person. And, since they are a natural to hide both inside and outside your house.
We guarantee that if you are not delighted with this knife for the price you are getting it for, we’ll refund the merchandise amount.
What is Zytel?
Zytel is used for a number of different high strength, abrasion and impact resistant thermoplastic polyamide formulations of the family more commonly known as nylon. Often it is with a fiberglass filler to add additional stiffness. Zytel is a trademark owned by DuPont. Nylon represents a family of synthetic polymers, a thermoplastic material, invented in 1935 by Wallace Carothers at DuPont. It is made of repeating units linked by peptide bonds (another name for amide bonds) and frequently referred to as polyamide (PA). Nylon was the first commercially successful polymer and the first synthetic fiber to be made entirely from the ingredients coal, water and air. These are formed into monomers of intermediate molecular weight, which are then reacted to form long polymer chains. It was intended to be a synthetic replacement for silk and substituted for it in parachutes after the United States entered World War II in 1941, making stockings hard to find until the war’s end. Nylon fibers are now used in fabrics and ropes, and solid nylon is used for mechanical parts and as an engineering material. Engineering grade Nylon is processed by extrusion, casting & injection molding. Type 6/6 Nylon 101 is the most common commercial grade of Nylon, and Nylon 6 is the most common commercial grade of cast Nylon. The most common variant is nylon 6,6, also called nylon 66, which refers to the fact that the diamine (hexamethylene diamine) and the diacid (adipic acid) each donate 6 carbons to the polymer chain. DuPont patented nylon 6,6, so in order to compete, other companies (particularly the German BASF) developed the homopolymer nylon 6, or polycaprolactam – not a condensation polymer, but formed by a ring-opening polymerization (alternatively made by polymerizing aminocaproic acid). The peptide bond within the caprolactam is broken with the exposed active groups on each side being incorporated into two new bonds as the monomer becomes part of the polymer backbone. In this case, all amide bonds lie in the same direction, but the properties of nylon 6 are sometimes indistinguishable from those of nylon 6,6-except for melt temperature (N6 is lower) and some fiber properties in products like carpets and textiles. Nylon 66 is a trademark owned by DuPont.
