Laws such as these are often open to interpretation. Especially so in liberals states.

Looking over CT law, I myself wouldn't chance it, even more so if the knife is emblazoned with the S&W logo and SWAT. And FWIW, Smith & Wesson doesn't actually make these knives. I believe Schrade currently makes them.

"Under the law, dangerous weapons are (1) dirk knives, (2) switch knives, (3) stilettos, (4) any knife that has an automatic spring release device that releases a blade from the handle longer than one and one-half inches, and (5) any knife that has a blade with an edged portion four inches or longer.

Illegally carrying a dangerous weapon on one's person is punishable by a fine of up to $500, imprisonment for up to three years, or both (CGS § 53-206(a)). Illegally carrying it in a vehicle is punishable by a fine of up to $1,000, imprisonment."

There are plenty of available options that are easy to open one handed that are not spring assisted. I like the Spyderco Delica and Endura for EDC.

YMMV
