The character Kendra is played by Bianca Lawson.
She named her favorite stake "Mr. Pointy" and let Buffy borrow it to stake Angel. Kendra didn't live to get it back. She was killed in the library when Drusilla slits her throat with her fingernails in Becoming I.
We only see Kendra slay one vampire during the show in the library in Becoming 1.
