There is great interest in defensive weapons that are readily available even in far flung locations and that offer some plausible deniability – think Ed Calderon’s (Ed’s Manifesto) fruit knife concept. These concepts are especially interesting to people who travel to locations that may not allow the freedoms to carry more traditional weapons.
Ruelas537 is a maker already known for crafting some sneaky defensive tools. Their newest product, the Omni Sheath, allows the user to carry something like a screwdriver (sharpened or unsharpened) close to their center-line on a static cord. The Omni Sheath protects the wearer from any sharp edges, presents the handle in a way that can be easily grasped and deployed, and releases from the screwdriver (or other object) “automatically” when the end of the static cord is reached.
