I've exchanged e-mails about this with people from TheRPF in the past.
I have several of these. Here is a link to one of them:

I really cannot disclose any details except that it has functionality, but it doesn't break any OTF blade laws. With a little tweaking it could be used as a weapon, but in it's current state it can't be used as a weapon. It is perfectly suited for X-Files fan videos which could show the blade open and close at the push of a button. The material is stainless steel. Lots of work went into this, and money, and time. Lots of trial and error. I have tons of 2D drawings for each part as well as a variety of 3D files in different formats.
Like it says on my page, it is not for sale. There is only one person I helped create this, and that's a good friend of mine, Brian Terranova.
He posts on this board as
Terrasolo. Perhaps he can put up a picture of his stiletto in this thread. His handle is made from aluminum and the overall design is just a little different than mine. He is also in the process of getting a second one made with slightly different functionality.
I need to finally put up a video on YouTube to show it in action.
BTW... if you search my posts on this forum you will find a post where I talk about this prop being definitely longer than 6 inches. This was a loooong time ago where I didn't even begin to do my research about it. That being said, after so many years I can finally retract that statement.
