An astonishingly sharp knife made from some of the hardest steel we've seen, it will hold its edge for a very long time and looks great while making short work of any food in front of it.
The unique shape of the bunka knife means that it is perfect for veg prep and for intricate tip work. The knife is made from a core steel of ZDP-189, a very hard steel (66-67 HRC), which means it can achieve and hold an incredibly sharp edge.
