Minecraft villager tool trade?

I wanted to ask if you can trade diamond tools with Minecraft villagers and if there's a villager for it, what job do they have to have?

If you trade often enough with them they level up and when they can sell you crazy things

Yes. The toolsmith at the highest level can sell magic diamond tools.

In German I think he should be called a blacksmith.

To turn a villager into a toolsmith you need a smithing table. Because this is how you do it:

You can of course use any type of wood. So it's a workbench with iron on top.

The armorer can trade you diamond swords, the tool smith can sell you diamond tools, and the armorer can offer you diamond armor. If there are pictures on the Internet showing all trades, you can look it up yourself

The blacksmith does that. For the job you need the blacksmith's table. If you level them long enough you can then buy Dia weapons or tools
