Titled Tohora Waiata:Whale Song. Knife by William Henry studio and engraving by Andrew Biggs. Andrew states at the back of the knife you can see the head of the whale and the body is represented by the two large spirals. The tail flows up to the front of the knife and is a stylized manaia head. The spiral bright cuts in the body reflect the light and when the knife is tilted it gives the whale movement as the light shifts down and around the cuts.
