Along with the OP's mentioned Kershaw DWO, and my mentioned Schrade SP3 and the Bucklite, I'll present another, the Gerber LST. IIRC, that is the one the others mostly copied. All of them are extremely light weight, are available in various colors (and blade lengths) and most can be attached to a lanyard for safekeeping. Regardless of steel, if she isn't going to be butchering animals, crafting wooden utensils, chopping firewood... these knives will stay sharp a long time for an occasional user. It would take a lot of string cutting, freeze dried meal opening, fingernail cleaning, peanut butter spreading to dull one. And they can all be found cheap new in the box. Sometimes, for some people, the simplist knife is the best.
