The tool shared freely can make a street need fewer purchases and more trust.

Most tools spend their lives idle. A ladder, a drill or a pressure washer sits unused for years in every third house, and buying one each substitutes money for the harder thing, which is knowing your neighbours well enough to ask. Sharing costs a conversation and a little inconvenience. It also builds the relationship the purchase was quietly avoiding.

Offer something before you need anything. Tell two neighbours what you have and that they are welcome to it. Lending readily, returning promptly and staying unbothered about small wear are the habits that keep such arrangements alive.
