If price is not a consideration, and she likes the Axis lock, then I would give some consideration to an Andrew Demko AD-20, with its Shark Lock. Andrew makes strong locks, and the Shark Lock is very easy to use.

For something less expensive and more readily available, the previously mentioned Spyderco Delica is hard to beat. Knife Center has exclusive wooden handled versions that look very nice. I have always liked the waved version of the Delica.
