The Los Angeles Tool Library will operate out of the Presbyterian Church in Koreatown for anyone to rent power tools, ladders and other items. Starting Saturday, the Los Angeles Tool Library will officially open. In this volunteer-run lending library, community members can borrow tools instead of purchasing new ones. The backstory: The idea began two summers ago, when founding member Chih-Wei Hsu was trying to build benches with friends and realized they didn’t have the right tools.
