I’m not big at watching YouTube videos but Project Farm did one testing chains. I liked the way he did the testing.
Semi might do what you need. What most folks use for dirty or sandy wood.
But if you run into something like I did this year. Carbide was only thing that make it cake work for me. Not the cheap china made carbide ones either that come apart easily.
You need diamond coated files to sharpen or to make it easier diamond dremel in size needed or diamond grinder wheel.

In the fire service we ran "Terminator" chains by Rapco for roof ventilation. As 5030 pointed out, a conventional chain would only last minutes. These chains did not cut, they ripped through the material because there was no passing of the chip through the link.
It was always amusing to watch a new firefighter try to cut a 12" tree. After he got frustrated, we handed him the "tree saw" and success.

I wondered about that bullet design one too for FD. I figured it does same thing as that one. Rips not cutting.In the fire service we ran "Terminator" chains by Rapco for roof ventilation.

If I'm cutting dirty wood, I just use .404 chain. It will stay sharp a lot longer than .375 or .325.
Old timber guys knew what they were doing...
Small chains became a thing when weight for a saw became a thing. Prior to that men just ran huge CC saws and big chain. I suspect they did more cutting per hour than we can today with smaller, lighter, and faster cutting set-ups.

I love chisel chains. Most of my chainsaw work anymore is making/maintaining trails. Lots of cutting off stumps at ground level. I've always "heard" how bad chisel chains are in dirty wood, but honestly, they don't seem any worse than semi chisel chains. Dirty wood does dull chains, but when that happens, I hand file them to (mostly) bring them back. After 5-8 repetitions of that, I get it sharpened at the shop.

There’s still places that run the long bars on the big cc saws but even then it’s not uncommon to see 3/8 instead of 404, the saws just don’t have the torque that they use to when from the early days they have speed.
