A little late to the party!
I bought three nephews and my niece - Opinels - each engraved with their names. I mucked up at bought them #5s which do not lock, the #6 does lock. None-the-less they were well received. Order direct from Opinel and you can add engraving. FYI, the factory edges are a little - meh - so I had them tuned up by my local knife shop.
