What's your favourite........

A teaspoon! The spoon end for lifting roots clumbs out of seed trays, and the handle for picking up tiny seeds with. The back of the handle is slightly indented which makes it very useful for those teeny, tiny seeds that would be difficult to sow in 2s or 3s without the precision of that handle.

I've got loads of other widgets for those jobs, but I always go back to the spoon.
