Carbon steel has good strength and hardness, but it is not rustproof; Powder steel has good rust resistance and hardness, but insufficient toughness; Spring steel has outstanding strength and toughness, but its hardness and rust resistance are not outstanding.
Therefore, there is no best steel, only the most suitable blade material (different lengths and blade types require different requirements), and I hope to treat it objectively.
Tool classification
1. Short knife: a kind of knife. The blade of the short knife is relatively longer than the handle (handle), and the handle can only be held by one hand or two hands. Single edge can be divided into single edge and double edge. Single knives include horse-chopping knife, The Lancet, ju knife, Yanling knife, big ring knife, tiger tooth knife and so on. A single knife is usually a single messenger, but it is also used with other weapons. Such as single-knife clamp, single-knife clamp whip, single-knife disc, knife clamp, etc. Single-pole is generally larger in style and heavier in weight. Dual-purpose knife, style and weight are smaller than single knife. Double knives include mandarin duck knife and butterfly knife. ?

Still to be verified).
3. Machete: used for foot combat. It is the same as ordinary hand knives, except that the back of the knife is thick, the blade is sharp, the tip is flat, it does not protrude forward, the handle is straight, and there is a knife ring behind the handle. During the period of War of Resistance against Japanese Aggression, this kind of knife was still widely used in hand-to-hand combat.
Sabre has a wide back, thin blade and heavy blade, which is beneficial to increase chopping power. Mongolian knives have smooth lines, and the handle is generally slightly curved in the direction of the blade, so the curved handle is more conducive to the rider's control and is not easy to get rid of. However, the blade of Mongolian cavalry sabre is thinner and lighter than that of military sabre. The superb riding skills of Mongols mainly rely on the powerful impact formed by the speed of horses to drive sabers to complete tactical actions such as chopping.
