After watching the Dune Extended Edition, getting a sheath to go with the crysknife replica I had in mind was imperative. In the extended cut of the film, we see the sheath during the scene between Shadout Mapes and the Lady Jessica, where Mapes was making the decision between killing Jessica, or entrusting her with the knife.
Existing crysknife replicas have never featured a sheath before. In my research I’ve only ever seen one attempt towards creating a sheath for the knife, but I haven’t heard about this since.
That’s why my crysknife replica features a matching sheath to go with it. And why not? After all, in Fremen culture, one has to be very careful about showing other people the crysknife blade—it’s important to keep it hidden. In fact, according to the book, a cryknife should not be placed back into its sheath without drawing! It makes the cryknife sheath all the more essential for the serious Dune fan and collector.
