Channel knife / peeler
Used to cut long citrus twists or peel garnishes with clean edges.
What it's for: Cutting citrus twists and peel garnishes.
Don't have one?

Purely cosmetic — affects the width and neatness of a citrus twist, not the drink's taste.
Buying guidance
Look for a sharp, sturdy blade that won't tear the peel.
