Pinus Koraiensis (Korean Pine) bark or Korean bonsai technique?

[Bonsai Noodles]

I've noticed Korean bonsai YouTube channels have pines with trunk bark that's very geometric/rugged. Is this due to a carving technique many Korean bonsai artists practice, or is this unique to their species/cultivars like Pinus Koraiensis? I've noticed their garden trees are especially grown to have bark with this character.

Second tree looks dead if pine. No needles. Bark on these looks much like Ponderosa Pine except is not orange. First tree looks huge based on length of needles. This bark does not appear man made but is perhaps Yamadori trees? How odd; with little research have found this is 5 needle member of White pine group but bark looks as if something else

It's very difficult to carve bark and keep it that way, because it flakes and tears where it wants to. So I believe this pattern is species specific.

Maybe a regional cultivar trait like in some japanese black pines (eg: Mikawa)?

I am growing one p. koraiensis and am very impressed with its vigor, to the point where I would call it a JWP++. I'm curious whether the additional vigor in this species explains the capacity for chunky bark as well.

Can you share some of the Korean bonsai youtube channels that you've found?

Sure! I'm also attaching some better images of what I mean by the bark. It's definitely... a Korean technique/species thing. I'm very intrigued.

I wish I could translate somehow. There are some videos discussing techniques, and it'd be interesting to hear how they approach bonsai.

Thank you. Most interesting.

Its just my (admittedly shaky) opinion, but most of those examples look more like red pines/pinus densiflora than koraiensis to my eye at least

assuming thats what they are - i've found red pine bark to be pretty variable from one tree to another...some have very flaky delicate stuff while on others it can be denser and heavier....likewise, even within those trees that are inclined toward heavier plated bark, some seemed more prone to forming longitudinal plates versus others that exhibited more geometric patterns

So i'm guessing individual genetics probably counts for it as much as anything
