Yes ditch the metal and blades and get a nylon framed ceramic hook knife from your local divers store.

+1 for the ceramic blade in plastic body
The one from Ventum comes with a neat harness pocket.

do you have a special rinse routine? i have had two eezy cuts trilobites that i take out of the sheath, rinse and air dry after every season and they still corrode.
I rinse with fresh water then pull it almost all the way out of the sheath just to the point the velcro will still hold it and then hang it up to dry:

Weird, this is almost exactly what I do except I actually take the blade completely out of the sheath and stick it to the velcro and it still corrodes.

Oh well...

Maybe try to stick it upside down, so the dripping salt water from the pouch doesn't reach the blade ;)
You can't take all the salt out of that webbing with just a quick rinse.

Or use a knife with a ceramic blade

Plastic body with ceramic blade, dakine hook knife, triilobyte, brand new mystic hook knife, bench made serrated blade knife.

I’m waiting for another ceramic blade knife and a gerber hook knife,

The trilobite does. Does NOT CUT through typical rope you would find as a leader line and it has never been used and the blade is rusty.

The dakine knife has the bubbling on the aluminum and has been my standard hook knife for several years. I replace them 2-3 times a year.

The mystic is the best at cutting followed by the ceramic blade knife, and then the aged dakine knife. I would not use the trilobite, it did not cut through leader line. Based on that I think the ceramic blade is the way to go.

With an open blade serrated knife you're more likely to cut yourself and those things are stupidly sharp. It is extremely difficult to calmly and methodically use a knife when you're in the water and waves are pushing you around and kites are pulling you.

Just a follow up. Dive rite ceramic blade, ion plastic body, ion, mystic, ezzycut, dakine, sea sword ceramic blades.

Spectra line and leader.

If you have an ezzy cut test it now. It did not cut through.

Also, the ion did not work, and it is a double blade and looks identical to the mystic so I would test your knife now.

The sea sword one side noticeably easier on one side than the other.

The dive rite is really good but they made the hole too small.

Bottom line test your knife.

Don't overthink it. Hook knives are cheap. Inspect the knife every now and then and replace it every year or two.

I wouldn't get too excited about the cutters listed above. They might be fine for diving where everything happens in slow motion. Not sure they're appropriate for a high speed emergency. They have a single blade with a plastic edge to push the line onto the blade. If you get a bunch of lines in there the outer lines won't get cut.

The hook knives sold for kiting (and skydiving and paragliding) have two blades in a vee configuration. The lines get sliced by the cutters from both sides. They can still get clogged if you have too much line in them but they're still better than a single cutting blade. If you have lines bunched in there you can yank the knife around a bit and the blades on both sides slice into the lines.

More importantly, all the harnesses I have used for the past several years have a knife pocket under the hook. They take the standard kitesurf knives. I'd rather always have a knife handy than have to mess around with accessory pockets and special maintenance regimes.
Yes I agree. I just replaced my spreader bar soi could use a fireball and it doesnt have a knife pocket…..i had better double check…..
