I finally got some reindeer antler good enough for the sheath with a window... Here is a result. Blade is hand forged by Alessio Salsi, it white paper steel at the core and 11 layers of non-hardenable steel on each side. Handle and sheath - reindeer antler with some carving. Initial photo. To be honest I didn't use the crown, other parts were all used.
Thank you guys! Well, that bar needs to be raised every once in a while. Otherwise it would be just boring... ))
