I would say the Gunting.
The blade is smallish, but extremely useful. Choking up on the horn works great for controling the blade. The handle is super ergonomic. It is easy to deploy and open, even in thick work gloves (using the ramp). The compresion lock is simple and super strong. Plus, the gunting has the benefit of being both legal and fairly sheeple friendly almost everywhere.
The Chinook is a big knife. It is significantly heavier than the Gunting. In some areas, it is too big to be legal. And it probably would scare sheeple.
Don't get me wrong - the Chinook is a great knife, and is very tough.
But, I would choose the Gunting between the two. And thats not even taking into account the many other uses of the Gunting.
That being said, I think there are other knives that are great for utility. You already said that you don't want a military/police/endura.
How about a Lil Temperance? With two blade choices, the compression lock, and an unusual grind, IMO, it is one of the best utility knives available. It has a stout handle, a good clip, is light weight, and fairly legal/sheeple friendly.
It has an advantage over the Gunting - namely, the fact that you don't have the nearly overwhelming urge to kin-op it on your thigh.
If you get the Gunting, get a trainer as well.
I didn't have the trainer, and I ended up trading mine. I think I would've eventually done something very stupid with it.
Good luck!
