Sorry I'm late

I don't know how I missed this thread until now.
There is a significant difference between kayaking and canoeing, whether or not you are using a sprayskirt and also whether you are wearing a drysuit & pfd or survival suit etc, because that determines what you can wear and where. But let's talk about the knife itself.
I really don't see too much trouble with any stainless steel on fresh water. Although I like carbon steel much better, you can be out there for a long time unable to clean and dry the knife, especially on expeditions, and nothing I've ever used, Tuff Cloth, Marine Tuff Cloth, Ren Wax, Vegetable Oil, will do the job. At least for me - other guys have more success. The trouble is finding a stainless you like. BG 42 ain't bad. 440V is tough to sharpen. ATS 34 isn't my first choice, but there are some great knives out there in that steel. VG 10, 440C [very underestimated], "stainless 3V": S30V...I guess there are a few good choices for fresh water.
For Salt water - forget it. They all rust too fast. Paracelsus had it 100% bang on. Talonite or Stellite is it.
Neil Blackwood, with the generous design assistance of Gus K, built me a fantastic "River Knife" in Stellite 6K which I use for river and ocean either as a neck knife or lashed to a pfd, depending on what I'm wearing. The top edge is serrated and there is an exposed and slightly flattened tang. A little on the small side for lightness. Fantastic. I also have a standard Blackwood single edge in talonite that I used before the stellite, and still use, and it's a bit bigger and heavier. To tell you the truth, I like the extra size and weight, but most folks may not want too much weight around the neck after 12 hours of slogging. That's fantastic too.
Everything you heard about talonite and stellite [at least if you've been listening to the right folks] is true. No corrosion. Cuts like stink[lubricity!]. Holds a working edge forever. Easy to sharpen. The only potential flaw is that it isn't that hard and may not do well resisting impacts or torque I was worried that this would make it lousy for hard ice in the Arctic or Antarctic, so I take a Busse and mostly carry it on deck or in my deck bag [I should use an ice ax but Busse don't make one

][Ice or no ice, I always like a bigger knife close to hand, but that's another story]
I don't know enough to give an informed opinion about stellite vs talonite. I have one "river" knife of each but frankly I haven't used them enough to have seen a real difference between the two! Thems who do know. Rob Simonich, Kit Carson, Dr. Lathe,Cliff Stamp, & others have expressed their views elsewhere. Kit Carson said he strongly favours Stellite 6k, which is why I asked Dr Lathe to do the custom in that material. But either material is perfect for a canoeing/kayaking knife on fresh or salt water.
And BTW, despite the compliments, I ain't no expert. I've just been extraordinarily lucky
