The Titanic is still here. What am I?
Iām white; perfect for cutting & grinding. For most animals I am a useful tool.
I am merry creature in pleasant time of year as in but certain seasons I sing that you can hear; And yet I'm made a by-word A very perfect mock; Compared to foolish persons And silliest of all folk.
What has a bottom at the top?

Whoever made me don't want me. Whoever bought me don't need me. Whoever use me don't know me.
