So no consistency by the cruise companies...
This is taken from the passage contract, which all passengers must sign before being allowed aboard:

14. BAGGAGE AND PERSONAL EFFECTS, LIABILITY LIMITATIONS.
You may take a reasonable amount of luggage on board containing only Your personal effects, which shall include suitcases, trunks, valises, satchels, bags, hangers containing clothing, toiletries and other personal effects necessary for the Voyage. If You travel by air or other transportation the terms and conditions of the airline or other transportation provider apply to Your carriage on those conveyances. You may not take on board firearms, weapons, knives, controlled or prohibited substances, inflammable or hazardous items, any other items prohibited by applicable law, or any other item Carrier deems in its sole discretion to be detrimental to the safety or comfort of any person. You agree Carrier has, at all times with or without notice, the right to enter and search Your stateroom, personal safe or storage spaces, or to search You, Your baggage and/or personal effects at any location.

Cruise lines are variable in what they allow or don't allow, but as seen here Cunard (as do other lines) reserve the right to prohibit items they deem to be detrimental to the safety or comfort of any of its passengers or crew. Thus, a sgian may be deemed threatening to someone's safety or comfort (as in my earlier statement about my bottle opener being "perceived" as a knife).

I personally don't think most mass-produced sgians should be counted as a knife, but I'm not in a position to enforce that opinion aboard a cruise ship or with a TSA functionary at the airport.
