Karesansui rakes

Quick answer：

Karesansui, also known as dry landscape or Zen garden, is a Japanese rock garden that uses gravel or sand arranged to represent a landscape. Rakes are essential tools used to maintain the beauty of karesansui by raking the gravel or sand into specific patterns, often in a Zen-like manner. These rakes are typically long-handled and have fine, delicate tines designed to create intricate designs without damaging the surface.
