Jeff- they weren't made as separate purchases. Don't know if there's an issue with posting a link, but here is the page:
http://www.tacticaldefender.com/ese...-point-blade-black-molded-sheath-p-52333.html
Note that the description doesn't say anything about the MOLLE locks, but since it is roughly the same price as other vendors for the complete setup, I figured it would be the complete package. Also, the pic of the sheath does show screws in the holes (wow double entendre), so I thought it would be complete.
For what it's worth, like I said in the original post, the knife was a gift from my wife, and she didn't know to look for the clips to be included. Caveat emptor I suppose, but this still seems like shady dealings on the part of TD- assuming it wasn't just an oversight, of course.
