How to Find this Item

There are two ways to craft "Sturdy Whetstone" iconSturdy Whetstones in Grounded. Both methods requiore players to visit a workbench and craft them using one of the following recipes:

The first method will require players to get sap. This is a commonly found material, which you can passively get via your Sap collecter players can build in their bases. The other material they require is the "Ladybird" iconLadybird shell. These enemies are typically found in the trenches around the BBQ spill site, along with the shed surroundings. It is easier to beat these enemies by using mint weapons or weapons embued with the fresh elemental type.

The other method is by finding Sturdy Quartzite shards. These are fairly common in the later stages of the game, and can be reliably found via the mid to late game labs, in caves, and the dungeon areas. Players can expect to find some in the early game dungeon areas, like the Red Anthill, along with the Hamster cave, Broken Lazer cave, the "Larva" iconLarva/ Acorn cave, all of which are in the grasslands area, albeit in limited supply. Other great areas for higher geared players are in the Sandbox caves, Termite cave, and other end game locations.
