Hatchets are cool,
To all their own. I find a largish sized fixed blade to be all I need when I go on extended 4 season backpacking / sea kayaking trips. Weight is critical, and honestly it works. Also it's way safer in my opinion, than swinging around a hatchet which really aren't that great at splitting wood. For an efficient splitter bit weight /profile and handle length are important.
But hey, if you are a hatchet person more power to you.
Curious though, what role exactly would be more "deserving" of this steel type and design?
It's simple,
Thin blades work against batoning, they get stuck more.
Flexible is irrelevant to batoning its thickness that splits not flexibility.
Flexibility is only important for using the wrong tool for the job.
I'm not saying this design can't baton.
But if your worried about flexibly your not selecting the proper pieces of wood to baton.
Lots of wasted energy trying to baton a big knotty piece of oak with a thin blade no matter how tough
a thicker blade splits wood better. It spreads the wood apart but it's still no axe.
What is this design "deserving" of?
It's more deserving of being a good knife less of a froe for wedging wood.
Structure is function.
We can't have it all. Everything has trade offs hence why I suggested that some of the merits might be lost on someone looking to baton pieces of wood so gnarly they need flexibility.
It's like looking for a Lamborghini with that can tow a boat.
I like the knife because it's not trying to do everything. Its focused on being an all around cutting and light chopping tool first and less of a cold chisel wood froe.
Axes split and chop circles around knives and this is a knife that complements an axe/ hatchet very well.
So hatchets are pretty cool and knives that focus more on being legit knives are really cool because you can really see the performance.
Anything that tries to do everything usually just sucks at everything.
But at the end of the day it's all preference.
Do as you wish
