The online community of knife collectors, A Knife Family Forged in Steel
A TL-29 or 27 would certainly be classified as a Knife of the Great Outdoors. Lineman used them as well as military electricians. They were and are used for good carry/work knives.
Some have collections of TL-29's so lets have their own site - right here.
Post those pics and info on this great knife.
Peter Force found out what TL stands for: Tool, Linesman
Now I wonder about the TL-27, if there is such a thing.
When I was a young Electrician, I did line work for the University of Louisiana. I used a knife similar to a Tl-29.
That was a great article - thanks Smiling Knife - I would love to have one of those Sheffield TL-29's.
Great, looking knife.
