Do you have enough money for it?, maybe try putting the tool in a chest and taking it out, and then taking it back to him.

Í try sleep for another day and visit him already.. still happening :( is it a bug or is it because I am in Year 1 so I cannot upgrade my pickaxe to gold?

Edit: I just put my tool in a chest and take it out again, went back to the blacksmith and I still cannot upgrade it.

Do you have a free Inventory Space?

The game treats upgrades like buying so you need at least one free space

[Choochu]

I have free space at that time, anyway I got my pickaxe upgraded after I waited for a sesson.
