What kind of knife does Beckett have in "Sucker Punch"?

it might be a small stilleto

I was trying to find something else out about this episode and i ran across this question and it stuck out in my mind cause i have that knife. Or at least a model similar. Its made by Kershaw. I have the 1660st which is the same one except with a serrated blade near the base. The one she uses is a 1660. The really cool thing about these knives is that they have a spring assisted opening so its almost like a gravity knife except still legal in California. Hope this helps.

Doesn't quite look like a Kershaw 1660/Ken Onion Leek to me, rather the slightly smaller and more curved Scallion, the bigger brother of the little and more female-compatible Chive (since it's Kate Beckett's knife, not Richard Castle's - who probably only has Nick Castle kitchen knives ;-)
