Grease Blizzard Knuckle

The Blizzard Knuckle (ブリザードナックル), or Grease Blizzard Knuckle (グリスブリザードナックル) , is a  device, a variant of the Cross-Z Magma Knuckle. Used by Kamen Rider Grease to transform into Kamen Rider Grease Blizzard.

History
Sento created the Blizzard Knuckle to try to defeat Evolto. Banjo also attempted to use it to transform, but failed.

Build Driver
The finisher accessed by the Build Driver depends on how many times the Vortex Lever is cranked.

Weapon
By plugging a Fullbottle into the top of the Blizzard Knuckle before pressing the unnamed Ignitor, Cross-Z/Grease can perform the Glacial Knuckle (グレイシャルナックル).
