This is actually a shank that was machined into a pyramid shape, like the original WWI trench knife. It has no edges and basically a pointy titanium stick. So I am guessing it is not considered a dagger or dirk but is it legal to carry in WA? I could find nothing in the RCW not even under dangerous weapons. From what I could tell it's ok to open carry this as long as no one is "alarmed" This is actually for the Mrs. while we wait on her ccw. She works in downtown Everett and ( thanks Ed Murray) we have been receiving bus loads of chemically dependent overachievers from Seattle to plus up our local numbers. So there is a credible threat now,even just walking to the hippie mart or local park. She is not allowed to carry a pistol at work because they sell alcohol and has to deal with meth addicted victims of inequality, often hostile, wanting access to the bathroom or free bubblegum. Pepper spray won't work very well on the walking dead, let's just accept that. Any thoughts in the legality of her carrying this around?I work odd hours and she wants something to keep goblins at bay.
