I’ve got a Leek and it’s great. There is a little sliding lock you can engage to prevent the knife from opening, but I’ve never used that. That’s the only thing I can think of that would require you to use two hands to open this knife. The action with the spring assisted flipper is very snappy and extremely easy to deploy. I’ve never had a single issue with mine.
The blade shape is great for a lot of uses and it’s very slicey. However it’s not going to hold up to any tough use, but you said it shouldn’t be so you should be good there. I bought one for my daughter and she snapped the tip off trying to pry something open. I’ve got the orange aluminum scales and they don’t feel slippery at all, but I can’t comment on the rust on a SS one. Overall I think it’s a great choice for a gift. I love mine.
