166.240 Carrying of concealed weapons. (1) Except as provided in subsection (2) of this section, 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. (2) Nothing in subsection (1) of this section applies to any peace officer as defined in ORS 133.005, whose duty it is to serve process or make arrests. Justice courts have concurrent jurisdiction to try any person charged with violating any of the provisions of subsection (1) of this section. [Amended by 1977 c.454 §1; 1985 c.543 §2; 1989 c.839 §21; 1999 c.1040 §15] found this from http://www.leg.state.or.us/ors/166.html . So I guess you can't carry any folder knife, but you can carry fixed blades that are not a dirk or dagger? But this includes any similar instument... So I can't legally carry a pocket knife at all? At least not concealed? This is crazy.
