这段视频展示了一只手正在使用一个黑色的工具来切割或雕刻一块浅棕色的材料，可能是皮革或类似物质。工具的边缘有锯齿状的设计，正在沿着材料的表面移动，产生一些细小的碎屑。背景是黑色的，突出了手和工具的动作细节。整个过程看起来非常精细和专注。
The video shows a close-up of a person using a leather cutting tool to cut a piece of light brown leather. The tool has a black handle and a sharp, serrated blade that is pressing into the leather. As the tool moves forward, it cuts through the leather, creating a clean edge. The background is dark, which highlights the action of the cutting process. The person's hand is visible, guiding the tool with precision.
The video shows a close-up of a black machine with a textured, beige-colored dough being fed into it. The machine gradually pulls the dough downward, stretching it as it moves through the rollers. The dough continues to be fed and stretched, becoming thinner and more elongated as it progresses through the machine.
