sheath for WMF 12 inch knife (Spitzenklasse)

The sheath fits. There will be powder in the sheath at the bottom (where the tip of the knife should be) and the dust will take some effort to remove. Washing the sheath will be recommended, using a wooden stick to scrape it off is also suggested. Finally, inserting the knife while there is some water in the sheath and removing the residue from the knife will remove the final bits of powder from the sheath.
