Positive surprise: there’s a locking mechanism. You cannot split the fork apart from the spoon+knife piece until you open it at least a bit. When folded, a kocking mechanism prevents separation of both parts.

Slight disappointment: you cennot separate spoon and knife. They are both in the same piece of the tool’s casing.
And the spoon is quite shallow, so don’t expect to carry much liquids at once. All in all, as an emergency set – it will do its job.
