I use twistpacks, plastic tubes in two halves that screw together.

I bought a job lot so if you want a couple let me know.
I protect crook-knife blades by winding a strip of leather around them. An off cut of thin leather a couple of mm wider than the blade is what you need and maybe a foot long. Hold the knife in one hand and grip one end of the leather strip with your thumb under the handle. Run the strip up the blade, over the top and then kink it off to one side. Then wind it around the blade 'mummy-style' and finish by tucking the strip thru' itself (like you would to finish off hanked cord). Easier to do than explain in words. Ben Orford supplies his crook/spoon knives like this and I've adopted it for my others. Not quite as neat as a sheath, but effective and easy.
