Marine Locking Knife?

[andyb28]

I want a locking knife to take out to sea. I have a jetski and a boat and realised recently that if we got a rope caught round the prop, not having a knife onboard could be quite dangerous.

However, I am quite confused by the law regarding this now.

I feel the knife needs to be locking for safety reasons, but I have read that these are illegal. However it also says if you are carrying a knife for a good reason, then thats ok. I wouldn't be carrying the knife around with me, this is obviously to keep on the boat or in the storage compartment on the jetski.

Does anyone have any recommendations on this?

Well, that sounds sensible.
