I'm leaning towards Rich's opinion on this. I own a handful of assisted opening folders (a couple of Kershaw Blurs, Benchmade assists, SOG Flash I & IIs, & some CRKTs) which I purchased before I read the statutes Rich cites below. Once I had read the statutes, I shelved the knives for non-carry use (I just use them around the house).
You may or may not successfully make the argument in court that these are a switchblade or not given what the CT law states (and if you're willing to go this route per your below comments, I'm very interested in what happens). IANAL, but if you do decide to carry an assisted folder you're probably best off carrying one which has a detent hole/ball bearing which provide bias towards closure (like the Kershaw Blur for instance) - I'm not sure if the SWMP1B has this or not. Maybe this could possibly help your argument in court...(or not). Rather than fight the charge on the tail-end it may behoove you to pay a lawyer up front to have have him/her weigh in before you start carrying. I guess you could also contact Knife Rights to see if they can assist you in any way (
