Sturdy whetstones recipe help?

[Padgey]

So I’ve unlocked the ability to make brittle stones which require larva spikes and sap, and brittle plating that requires sap and grub hide, so I’ve managed to get my weapons to level 5 and my armour to level 5, but to goto levels 6/7 I need sturdy plating and sturdy whetstones, I’ve completed the haze pond hedge red and black ant hills termite den and picnic table yet still can’t craft my own sturdy rocks, and I don’t think they respawn anymore? So what do I need to do to get the recipe to craft my own I think during early access it used spider fangs, anyway any help would be good as I wanna go explore the upper yard but wanna be stronger then level 5 weapons and armours when going up there

I believe it's the black ant lab or the sandbox chip.
So u can turn sturdy quartz into whetstone.
But that stuff is super rare I find as you need 2 for 1 mighty ingot or what ever it's called. Level 6 needs 10 sturdy whetstone and lv 7 needs another 20.
I can craft brittle from bug parts but not sturdy. Nor can I upgrade brittle to sturdy.
So I hope there is a way to get sturdy via crafting as not needing the non respawning clumps.
Also got all chips except the one in the far upper NE yard. And still havent unlocked supreme plating/whetstone but I have unlocked the ambiging receipe to finish the game I'm assuming.
This sturdy quartz is to rare. And is needed as a base crafting mat for many weapons on top of it being a major cost in ALL weapon upgrades.

sturdy is in the stump chip, and surpeme is basically when you complete the game

So, they give you access to supreme after you no longer need it.
Sounds like something a deviant dev would do.
