Is there any way to reset the spiral tool?

Hi Community,

I used the spiral tool in combination with the control key.
I did something wrong I guess!
Now all I get when using the spiral tool, is a skimpy arc.
I want to be able to reset this tool so it behaves like in the beginning.

Some site advised to trash illustrator preferences, but doing 
that made me lose all my workspaces, I worked so hard to create.

I wonder if there is any way or button to reset a specific tool to
factory settings without having to trash my preferences?
