I love the folding hunter. Call me a heretic, but I don't really care for the Buck 110 types. Granted I carried an a Schrade or UH LB7 on my belt back in the 70s, but I moved away from it not long after.
Considering that you are carrying an Ecolite version of the 110 I'm not sure how much lighter they are than the standard 110. So a folding hunter may end up being a tad heavier than the Ecolite. When I worked security at a place that built flying palaces for foreign heads of state and a few professional sports teams I carried a Queen FH in Birdseye Maple and D2 steel in my back mag pouch. (Hey, I figured if it wasn't settled in two mags either I was screwed or should have backed out and contained instead.)
I just tucked that Queen into my back pocket as I'm sitting here. As long as it sits vertical along the outside of the pocket it rides fine. I don't carry thing in my back pocket since things there tend to press on nerve spots that aggravate my back problems. However, sitting here the FH is not a bother. That is until I stand up and it falls over. The trick to that is to place a folded handkerchief in with it to hold it in place when standing. It can be done.
I also just tested it in my front jeans pocket which has a LOT of stuff in it: keys on a carabiner with braided cord lead, Alox SAK Farmer, Ronson torch lighter (slightly thinner than a Zippo), Chapstick, single motorcycle key, and a twice folded piece of fiat currency (AKA U.S. Dollar). It's carrying well. I just walked to the back door to let the dog out and it's fine. That doesn't really surprise me as I've found a single blade Granddaddy Barlow carries well in the front pocket too. The trick is that it ride along the outer edge of the pocket and vertical. The rounded lines of the folding hunter make it a lot easier than a 110 type for the pocket. The trick again is having something in your pocket to keep the knife in place.
But, that's the trick to carrying any of the stuff in your pocket. As long as everything has settles into a comfortable place and stays there it carries well. I actually made a smaller, thinner pocket lanyard for the keys and it carried so badly afterwards that I had to put the bulkier lanyard back on. The bulkier lanyard kept things in place and the key wad from settling in too deep. With the smaller lanyard everything just wadded up in the bottom of the pocket. No worries though. I just put the smaller, skinnier lanyard on the Alox Farmer and all is well.
I also have a Case 2-blade FH with bone, but it's stainless. Can't tell a lot of difference in weight between it and the Queen. The Queen may be a tiniest bit heavier. Dimensions are about the same so the Case should carry about the same as the Queen I'm talking about here.
As for the lack of a lock it depends. If you spend a lot of time twisting, forcing, and otherwise putting a lot of pressure from various angles on your knife then a locker is probably a good idea. If you just use the knife to cut things and keep the pressure downward, edge first, then you shouldn't have a problem. As long as the knife has a good spring, not mega heavy, but one that takes a little bit of a push to start to close (and that's also to do with how the blade/spring mating surfaces are cut) then it shouldn't be a problem. I closed enough knife blades on my fingers until it started to dawn on me, "Dummy, it ain't supposed to be used like that! It's a cutting tool and it only cuts in one direction. Use it that way!" Much less problems since then. Amazing how that works.
So yes, you can pocket carry a folding hunter even though I'd recommend a belt sheath if you can. For pocket carry find one with bone, wood, or Delrin handles if you can as they seem to be the slightly lighter. Stag is heavy. Pretty, but heavy. Then use a simple trick or two to keep the knife riding in place.
