Here is an update on my experience with Celebrity. TLDR -- I was not allowed to have my hex keys on board. As a compromise, they let me have my tools when I disembarked at the next port but I had to return the pouch when I returned. The staff (security, Guest Services, etc.) were all very courteous and professional but were very insistent that I could not keep my tools with me on board. I jokingly asked if they were worried I would take apart their ship. They laughed and said yeah, something like that.
Getting my tools back after the trip was easy. All confiscated items could be found after customs near the street side. Security checked my ID, asked me to sign the release and gave me back my pouch.
Good thing I didn't bring my scuba knife, o ring pick set, etc.

I just completed a 7-day Caribbean voyage. Security, during embarkation, found my tool pouch which contained a set of hex keys (for setting up the arms on my camera), a very small Swiss Army knife, a Philips screwdriver. They were ok with my Swiss army knife (very short blade) but not to my tools (specifically my hex keys).
I gently (in a non-confrontational manner) showed them the Celebrity prohibited list (see
Preparing for Your Cruise FAQs | Celebrity Cruises) which didn't mention tools. They showed me their security list which said no toolboxes, no power tools. I again gently said that I didn't have a toolbox or power tools. They then said they were sorry but no tools.
Being a frequent traveler for work, I knew that I should not press it. So I asked if I could assemble my camera housing at a security scanning table. They allowed that. They also said that Guest Services on board **may** allow me access to my tools.
On board, I needed to adjust the housing and arms more so I called Guest Services. They were also very courteous but insistent that I couldn't get my tools. I asked if I could adjust the camera in front of them at Guest Services under their supervision. They said no again. As a compromise, they said they could give me back my tools pouch when I disembark for my dive trip but I had to (and they were very emphatic) return them when I reboarded.
