I have that one as well as the TDI 1480, which is the larger model with a 2.31 inch plain blade. I really like it, with one caveat: it is very small.
When I say small, I mean tiny. The blade is not even two inches long. It makes a good, "Im about to be pulverized", absolute last ditch weapon that one can grasp between fingers and deliver punches with. It is so tiny that it even can be used as a keychain attachment.
That said, I like it. But I would recommend getting the larger TDI. Easier to hold, small, municipal-friendly blade, and (if your the BG) hard to take away. And still only $25-30 before shipping. Heck, do what I do, and get both for her. You should be able to get both for under $50 shipped from vendors like bladematrix.tv or lapolicegear.com.
