There is a specific kind of tool I want that is used to scrape the surface of vegetables in order to turn them into thin strands for spaghettifying or hash browns, but I don't know what it's called.
From your description, I think you are referring to a julienne vegetable peeler.
There are many different styles. Some may julienne on one side and peel on the other. Others may have interchangeable blades. And, as you can see in the lower picture, they can make different size cuts.
If you do a Google search, I'm sure you will be able to find one that will suit your needs.
A spiralizer makes long strands, or a mandolin would also do the trick.
