I just got them (yes,
them), so I actually paid 20.5 cents apiece for them.
Somebody must be taking a beating on these to sell for that low and to double up my order to boot.
Postage was reasonable too ($1.49 charged, actual cost $1.03 plus they came in a padded envelope easily worth the other 46 cents), so I didn't get ripped off there either.
Imagine that. Not all that bad little light-up knives for less than the cost of an envelope, even less than the cost of a letter stamp.
Well, I'd better go leave the guy some nice feedback. I'll shoot off a couple of pictures later. Heck of a deal here.
(Edit) Done, and done. Pics taken, to be uploade later. The knives have locking blades, and they use a 3mm red LED and a single CR2032 lithium cell. The cell can be changed easily, though you do have to pay attention to what you're doing when you put it back together. The switching mechanism is simple enough: properly-cut LED leads, a plastic button, and a spring. The spring & button arrangement pushes the battery against the LED, rather than the other way around.
The blade is labelled "STAINLESS CHINA". Maybe not the best stuff around, but it is stainless steel and should be resharpenable as needed. A small projection screwed to the blade acts as a thumb opener (there's probably a name for that, but I don't know what it is) so you can open the knife with one hand. The blade lock appears to be sturdy and secure, functionally identical to the Kershaw 1600. When open, blade wobble is nonexistant if the brass pivot screws are secure. What more can you ask from a 20 cent knife?!?
