What It Does
A Quartz Knife doubles the amount of seeds and/or worms that can be hollowed out of a Bell Pepper. Each use removes one gold value from the value of the knife and if the knife hits 0.00 gold value then the knife will disappear from your inventory. A knife can have uses added to it by sharpening it on a Rough Stone.
- Assuming you have more than one knife, they will stack in a hoard. This can lead to uneven gold values and issues with accidentally pulling out more than one knife and using both at the same time. Be careful when stacking knives in hoards.
How to Acquire
The very first pepper crop that a player picks will yield a knife. Other than that Quartz Knives can be acquired by buying them from the toadken store.
