Finishing for marine environment?

[DanDSilva]

I recently assembled this knife.  The conceit in its design is that it's owned by a sailor, so it's got stabilized grips, stainless and brass parts, etc.

I would like it to have a somewhat traditional leather sheath, something like this:

What kind of dye and finish can I give it that won't bleed dye, won't crack if flexed, and will hold up relatively well against saltwater and shifting humidity?  I don't expect it to be immortal, but I'd like to prolong its lifespan.

Currently have on hand Fiebings USMC black, Fiebings brown and black LeatherColors (the water-based stuff you'd find in an arts-and-crafts store), Leather Sheen, Resolene, Liquitex acrylic varnish, mink oil, pure neatsfoot oil, olive oil, Leather Lube and Sno Seal.  If that doesn't suffice, I can order additional supplies when we get to June.

I reckon a brown oil dye and a real good coating of a beeswax/nfo/carnauba wax mix applied and rubbed will in and buffed. Maybe a few coats of the wax mix

sno-seal would do a good job of protecting it

I'd go for pure neatsfoot oil. 

I just checked with our bosun, and here's a picture of his sheath.

It is a nice touch to make room for a marlinspike in the side, and the D-ring for securing the knife and the marlinspike when working aloft.

Thanks!  So, if it's thoroughly buffed, oil dye won't need an acrylic sealer?

Very nice.  Is the color dyed or just from a large amount of oil?

See if you can lay your hands on a copy of Ashley's Book of Knots. He's got a thing or two to say, from a hundred years back. Fish oil and engine oil...

My saddle on my motorcycle is made of veg tan leather that has only been treated with neatsfoot oil.  That has held up for the last 27 years so far. I have reapplied some oil to the saddle every now and then, but that is all.

I think the colour of the sheath is dyed brown from the tannery,  but I am pretty sure that it too has been given some oil over the years. Normally the leather stuff on our ship would get either tallow or something called lanopro wire oil. But that is just what we use here.

you might as well leave it natural after using neats foot or any of the other methods it will be very dark. especially after a few years of reapplying. Beautiful knife by the way!

Thank you.  I think I'm going to try a few combinations on test swatches.  My preference is a dark color from the start since black or dark brown seem to be traditional with this style, but if I can't prevent bleeding, then a deep saddle tan from just oil and wax will have to suffice.

By the way, anyone have any thoughts on the sheath and frog combination that Weber offers for this blade?  Is it likely to be good and secure against both the knife accidentally popping out of the sheath and the sheath popping out of the frog, or could it use improvement in that regard?

The frog on the web page you linked to looks like a 'general purpose' frog. It holds the sheath loosely. Its alright for when you are upright but I think it'll be too loose a fit for a sheath on someone clambering about a boat.

If you are making the frog, wet mould its loop on the sheath with the blade in it

When I made this frog / hanger for a stiletto knife sheath I wet moulded it to the sheath. The sheath could never be pulled out
