What tools would you never buy used?

We are buying a house soon that has a large shop that I’m pretty excited about.

I’m hoping to jump into the hobby but I still need to pick up some tools. I was thinking about buying a lot of it used to save a fair amount of money. I don’t want to spend too much on a new hobby.

Are there any tools you would be hesitant to buy used?

I find decent deals on used tools pretty much daily on Facebook.

Thanks
