Some sort of letters and numbers , but not wd 40 ( which would work short term )

Well, it's never going to be the cheapest, I can assure you. It might possibly turn out to be the best investment in a knife though!

Having said that, my Gerber, at a bit less, has stood up well to 5 or 6 years in the damp front pocket
of a BA with an annual wash in freshwater, and is still frighteningly sharp and effective. By tying it on with a carefully selected length of cord it flicks open when you extend your arm while holding it. Works well for me - though thankfully I've never had to use it in anger.

In their training vessel checklist the rya say a safety knife should preferably be serrated. This is because many new types of rope cannot easily be sliced through but are better sawn through.  The big fish type knife is pretty useless as a safety boat knife for this reason as well as the 'jaws' being too narrow for thicker lines or sheets,  plus it is almost impossible to sharpen.

One of the best set ups I have seen is a shortened bread knife in a sheaf made from a length of plastic pipe.  So it's held securely in place but is really quick and easy to access. Plus cheap to replace when you lose it overboard of it gets blunt.

The fish knives are ok for trapeze safety and personal safety, but I prefer a serrated knife for the reasons given.
the same, but different...

That's my point £50 to save someone else or your own life is soo cheap. I have the gerber and whilst their other knives are generally decent quality, they have out a decent blade, but a steel hinge in it, so guess what? I have to wash it every sail as it rusts visibly. They really should know better. The boyes knives are great and if I was on a round the world trip, fine, but too pricey otherwise.

I wipe a light smear of oil over my knife after racing, to keep it from corroding. I agree how disappointing it is when the rust appears despite all claims of stainless etc.

Something that has just struck me, is that I've never tested my knife. I have no idea how long it takes to slice through a mainsheet, for example. I think I will test it now, as I'll then know if it takes too long! Better to know, in case I need to buy a new one.

Just out of interest, how many people carry knives? And what boat do you sail?

Edit: Probably better as a new topic which I will do now.
