There are often more restrictive laws against weapons that are not firearms because the 2nd amendment has been held to concern firearms, not weapons in general.

There are often more restrictive laws against weapons that are not firearms because the 2nd amendment has been held to concern firearms, not weapons in general. E.g., in Seattle any fixed blade is illegal to carry. Even chefs have to take special precaution if they want to carry their knives to and from work. Same for hunters/fishermen (fillet knives) heading to or from the wild. In Oregon (and probably most states), it is illegal conceal most knives, except pocket knives. Often, the same laws restricting knives cover brass knuckles, clubs, etc. "any person who carries concealed upon the person any knife having a blade that projects or swings into position by force of a spring or by centrifugal force, any dirk, dagger, ice pick, slungshot, metal knuckles, or any similar instrument by the use of which injury could be inflicted upon the person or property of any other person, commits a Class B misdemeanor" https://www.oregonlaws.org/ors/166.240 https://www.oregonlaws.org/ors/166.240
