This is a pattern welded gyuto, the steels used are 1095/15n20. The pattern used for this knife is an experimental mosaic that was made in house. It reminds me of falling snow but could also be referred to as a starburst type mosaic pattern.   

This knife has a compound S-grind, which is a hollow along the middle of the blade which aids with food release. I would consider this knife to be more of a normal grind for general kitchen use. 

The ferrule of this knife ancient interior mammoth ivory. You can see the subtle cross hatching in the ivory in some of the photos. The main block of the handle is ancient redgum from Australia. It’s very dark with a red tone to it.
