Psychic weapons.

These days there are many rites and pseudo-religions that manipulate spirits or resort to demons to harm us, so there are times that the only thing we have left is to defend ourselves, and one way is through psychic weapons, which consist of weapons made of metal, such as pocket knives, knives, swords, ninja stars, among others, the ideal is a knife with a wooden or leather handle, and a well-sharpened blade , preferably double-edged, since metal attracts evil spirits and the edge hurts them, so they prefer to get away than suffer the pain it causes them. And on tough days, the knife can be set upright point up for greater effectiveness.
