Wrist blades are knives worn on the wrist, often retractable and hidden in a casing. They are popular in video games and can be illegal in some regions. They require skill to use and must be carefully designed for safety and quality.
A wrist blade is a knife designed to be worn on the wrist. Such blades are popular features in video games, and are less commonly seen as practical weapons, although wrist guards are made by some companies. Enthusiasts have also built their own, working off designs developed by others or creating a blade from scratch.
A typical wrist blade is designed to fit into a casing worn on the wrist. The blade is usually retractable, hidden in the casing when not needed. In some cases, the blade and housing are a unit mounted on a wrist strap, while in other cases, the blade is integrated directly into the strap worn on the wrist. The strap should be wide, to keep the blade stable while in use and to accommodate the blade housing.
The nature of a wristband classifies it as a concealed weapon. As a result, in some regions, using such a blade may be illegal. In other regions, a concealed weapon may be legal, but there may be limitations on blade length that are designed to protect the safety of members of the public. Some enthusiasts may be able to circumvent the law by using sharp or game knives instead of real knives, although this practice is not always advised, as law enforcement may not realize that the knife is not dangerous.
Learning to wear a wrist brace requires skill and training. The placement of a blade on the wrist is not entirely ideal, in terms of fighting technique. Some wrist-worn blades are intended to explode when deployed, giving the user quick access to a sidearm. Others must be long, to extend beyond the hand, and the casing must be carefully designed so that the user does not sustain injury while using or using the knife. The casing may include a hand guard that prevents cuts when the knife is in use.
As with any type of blade, the quality of a wristband can vary dramatically. The metal used in the blade has a profound impact, as cheap metals are more prone to wear and fracture. The materials used in the retractable casing are also critical. Cheap materials can snag or break, making the knife inaccessible or left in a partially extended position. The wrist strap and protective guards must also be carefully designed to allow full range of motion and provide protection for the wearer.
