The online community of knife collectors, A Knife Family Forged in Steel
One of the best to use for a neck knife (as far as with the original sheath) is the 601 with the double guard. I run a lanyard through the sheath drain hole, put a knot in the end that can be drawn into the sheath, then I knot the other end after passing through an overhand knot at the drain hole. The knife goes in the sheath either way. It's small. And, safe to use.

Moras make wonderful neck knives in my opinion, you can't beat that edge, and keeping it handy at your chest saves a lot of time no matter what the task!
Thanks Ivars, I am surprised that you had a spoon carver with a double bevel. The ones I've seen are laminated blade. But, it should not be visible. If a laminated blade is not sharpened with the stone laying flat, the stone can cut away the harder steel, leaving a secondary bevel, which would be at a different angle than the intended angle. More of a blunt edge in comparison to what the factory edge was. Some use a wooden dowel rod wrapped with sandpaper for sharpening.
