A few weeks ago I picked up this Camillus electricians knife at a local gun show. It is an older one made when Camillus was in New York and long before their name was being put on $5 knives from China.
Nothing real special about this folder. It has a 2 1/2" folding blade and a screwdriver. The screwdriver blade has a dull edge that could be sharpened if one wanted to. It is kind of a handy knife to carry around the farm. The screwdriver blade is held by a liner lock when open. The knife blade is a simple friction folder. Very tight on this one too, a fingernail breaker if you are not careful when using the nail nick. I have seen some of these knives with a metal loop on the end to fasten to a clip but this one has no sign of one being on it. The handle is some type of plastic, Delrin perhaps, but feels good in the hand. The liner lock is brass and protrudes from the knife in a manner making it easy to use with your thumb.
The knife is 3 5/8" closed and 6 3/8" long with the screwdriver blade open and locked. Model is a TL 29 I think and the steel is carbon steel, either 1095 or 0170-6C depending on when it was made. These were supplied to the military under contract and were regarded as well made knives.
The Camillus is the black knife in the photo. The other is a Grohman belt knife I posted earlier.

I was happy with how this one cleaned up and have been carrying it in a small belt sheath. It seems to be quite easy to sharpen and holds its edge well so far. I was cutting a lot of cardboard boxes down to throw away the other day and it was still pretty sharp when I finished. In some ways it reminds my of my old Boy Scout knife without all the other blades probably due to the shape of the knife blade. I got this one for $8.00. I see them online for $2.25 plus shipping on the low end to well over $125 if in as new or unused condition.

Boker made a knife almost exactly like this one, a model 9229 with a different brown handle material. I don't know who copied whom.
