I was pulled over recently, for speeding, and the officer asked if I had any weapons on me. I told him about 2inch Winchester blade I keep folded in my pocket, that I use quite frequently at my work. He told me that it was illegal to conceal any knife no matter the size. He just asked me to take it out of my pocket and put it in my center department, which I did. He was nice, so I was cooperative. I'm looking to find out the legality of carrying knifes in yamhill county, or oregon in general. Where can I find this information? I feel naked without my knife on me, haha.
