I used Rhino 2 sr3 for the modeling. I inserted the blade image as a background and traced the contours. Based on the image of the blade I assumed that it pivoted on the third hole. To make the knife actually close and hide the end of the tang I will have to change the handle from the image you posted and make the guard longer and grips wider to cover the blade. This is what it looks like closed. there aren't actually pivots or a blade recess modeled. Is this what you want? Knife is in OBJ format scaled to be the height of Vicki in poser. The OBJ file is in the open position and you will have to import into poser and rotate if you want a working prop. I have a map from uvmapper I've included but haven't textured it. The default colors are what you see from Rhino. If you want changes let me know.
