Cold Steel Heavy Sure Strike 3 Pack Throwing Stars - Black

1055 is a medium-carbon steel with a carbon content of 0.5-0.6%, characterized by a good combination of hardness, impact strength, and resilience. It is a steel with a simple chemical composition, containing mainly carbon and a small amount of manganese (0.6-0.9%), which improves the impact strength and hardenability of the material. Thanks to these properties, 1055 steel is widely used in the production of machetes, bushcraft knives, swords, and tools designed for heavier field work. After proper hardening, the steel achieves a hardness of 54-57 HRC, which ensures high resistance to cracks and chipping, but at the same time makes it easy to sharpen. However, due to its relatively low abrasion resistance and susceptibility to rust, this steel does not retain its sharpness for long.

Epoxy is a plastic material made from chemically cured epoxy resins. It is characterized by high mechanical strength, resistance to abrasion, chemicals, and moisture, as well as very good adhesion to various surfaces. In the knife industry, it is mainly used as a binder in composite materials such as Micarta or fiberglass and carbon fiber laminates, thanks to which the structures remain durable even with intensive use. Epoxy is also used in adhesives and protective coatings, increasing the corrosion resistance of components. Thanks to these properties, it plays an important role in the modern production of knives and outdoor accessories.
