I have a zytel ladybug and a stainless jester...I like the ladybug better just for weight sake. I think cutting ability is the same. Get her a sweet pink or red ladybug.....She'll love you for it.
Last Valentines day I got my wife a zytel harpy...for defense. I instructed her not to show the knife until used, then, quickly go for the eyes/neck/face. She wasn't thrilled then, but, after nearly a year clipped to her purse; she loves it! She refrences it often. I'm thinking of giving her the "Civilian" I just got, I don't like it, and it would suit her needs better. (She's an Emergency Room RN at a hospital in a fairly dangerous city. I worry about her getting to her car. (She also carries an ASP "key-defender" in bright pink and loves that as well)).
"knives are great, but, there's nothing like a shot of pepper spray to the face to stop a fight."
