In MA it is called a LTC (license to carry firearms(aka as hanguns), and there are two types A(for any thing that can take more then ten rounds) & B(under ten rounds, and most of the time restricted to target and hunting, no CCW on person)), IT DOES NOT COVER ANY OTHER WEAPON. Only firearms (and Mace/pepper spray).
We also have a FID card for long arms and mace. Oh and lets not for get the AG's office has a list of "BAD" guns (like Glock, Springfield XD's, etc) that the sheeple / subjects are not allowed to own (but cops can, go figure). The AG's office tried to pass a law banning hundreds of handguns they called "Saturday night specials" when the law was shot down he then took the same law he just lost on and made it fall under the AG's offices "consumer protection regulations". POW, instant handgun ban!!!! We also have an assault weapons ban.
You also can not carry on your person any type of impact weapon (this can include Maglites in some situations), daggers, switchblades, etc., I'm pretty sure there is a ban on butter knives too.
(can you tell yet I hate MA, and the loony left that run it)
As for FL, they have a much less restrictive system down there. With the size of the Izula I would belt carry it (there fore it is not concealed). I have belt carried (open carried) in FL before and had know problem at all. You could try asking the AG's, local or county LE. (here in MA if you call any of them they tell you to hire an attorney to "interpret' the law for you. I know this for a fact as I have called them on several occasions, "I'm sorry sir, we do not give out legal advice". WTF)
I did have a cop here in MA question me once on my Izula. I have a copy of the state law in my wallet and bag just in case. He wanted to see the knife (fishing to see if it was double sided, aka as illegal), once he saw the blade and the size he was ok with it, and was asking a lot of questions about it (I think we may have a convert). Also it is not a knife it is a tool (not a weapon), like an emergency seat belt cutter.
look at the top of the molle teklok, you will see the loop in the lanyard I throw over the top.
I also wrap my Izula in red, purple or safety orange para cord if I think it is going to be questioned (depending on where I am going). Oh and DO NOT use a lanyard with a skull on the end, as cool as it is and I do love them, think "low key" not a weapon. A skull implies that it is a weapon of some kind to some, but a bright colored wrapped handle and lanyard projects "tool" "helpful" etc., I know it is nuts but it works. If your right handed, wear it on your left side, now it is not easy to draw and thus is not a weapon (to someone that has no knife fighting experience or training, most cops don't).
