Identity of this knife?

[redferd]

It is a Kershaw 4510. About as large as a Buck 110 folding hunter but has a little red lever on the side to assist it opening and closing. The lever pushes the blade up out of the handle and a nail notch becomes available to open it fully. It's a nice looking knife in brand new condition. The handles are made of black FRN. I was wondering how old it is and what it may be worth?

Here is the serrated version...

...looks like a recent model that may have have been discontinued.

Thanks for the information. I like the knife and the blade is well hidden in the handle. The lever flips the blade up just enough to get my thumbnail in the notch. Also it acts as a lockblade. The lever is used to close the knife also. The lever releases the lock to allow the blade to close.
