How would I make a game automatically save and load tools via Data Store?

I have been working on a multi-place game and I wanted to implement a shop where players can buy tools to use in the game via Data Store. My main problem is that I don't know how to save tools using Data Store. I know that it has something to do with bool, but I don't know what a bool is or how to work with it. Being rather poor at scripting and not knowing the first thing about Data Store, I searched the free models section for help. After a few hours I realized that it probably wasn't there so I went to YouTube, Google and the Roblox forums for help. This has gone on for two days now, but this was going to be a big part of the game so I couldn't just give up. All I need is to know how to have the game automatically save and load tools into players inventories. I would be grateful for any help, thank you.
