In 1991, I learned the hard way that the legal blade length in RI was 3”. The Buck 110 in my pocket was measured at 4-1/4”. I spent 11 hours in a cell over that, and was later released to my ship. My knife was forwarded to NIS, before it was called NCIS, as evidence, and returned to me after case disposition. When I was arrested, my knife was literally razor sharp. It never had an edge again after I got it back. I have no idea what they did to it, but it was impossible to sharpen.Now you know why it got left where you found it.
