One little trick to help see if there’s a hinge pin or not is to use a pencil on the bolster. Even a pin that’s so well fitted that you can’t see it, will show up with pencil graphite.
But besides Schrade and Camillus, it could have been made by Ulster.
You are so right, Gary ~ the TL-19/Electeician/Linesman is quite pleasing to my eye as well!

And the variations found between the dozens of brands is interesting.
It is quite a rabbit hole trying to find out where some retailers sourced their knives. Not only with TL-29s, but Sears, LL Bean, etc.
See, that’s why I’ve never taken up mushroom foraging ~ except for morels in the Ozarks.
But I do try to innoculate piles of woodchips to break them down into humus. I love sticking my fork into a pile and see it full of mycellium hyphea.
Cool photo there!
Ha! Love that colliquialism, Will.
I am going to use that next time the time is right!
Thanks for taking the time to post your photos, John.
You’ve sparked a memory of my late son.
While his team was way out in the middle of nowhere in Khandahar Province, they met up with an Australian team, and spent some time making friends. One tradition is for guys to trade patches, even medals with allied soldiers. Jason and an Aussie took that one step further, and traded a complete set of BDUs.
I have that Aussie desert camo uniform stored in one of his lockers. I really don’t know what to do with them, maybe a museum would like them.
As good a reason for carrying Schrades as there is

Good luck with your research! But Schrade, Camillus, Ulster, Western… they are all as good as a knife can be.
Nice, Rick!
How’s that for a collector’s dream…find an old box of 12 Russel Barlows!
Like finding a ‘53 Telecaster someone stashed under the bed and forgot about
Safe to say the trails are not from incoming cruise missiles!
You’re not in Kiev, right?
Great collection, Jer! Thanks for the photos.
Woodsman in micarta! Nice upgrade from the standard black.
