One of the essential tools in this craft is the Genno, also known as the Chisel Hammer. Mastering the use of the Genno is crucial for creating high-quality Japanese furniture. In this guide, we will explore the basic skills and techniques necessary to use the Genno effectively.

Proper Posture and Grip
- The key to successful chisel work with the Genno starts with your posture. Hold the hammer so that you can comfortably bend your arm at a 90-degree angle.
- Grip the handle with your hand positioned slightly short of the end, and ensure that your elbow remains elevated.
- Widen your chest and use a lateral wrist rotation when striking the chisel head. This technique is essential for precise and controlled strikes.
Striking Technique
- When using the Genno, it's crucial to strike with a flat surface, slightly rounded on the opposite side. This ensures that the energy is transferred effectively to the chisel head.
- Always maintain focus on the cutting edge of the chisel and the processing point. This visual feedback is vital for accuracy in your work.
Common Mistakes to Avoid
- Straight wrist Avoid a straight wrist as it can lead to wrist injuries. Keep your wrist in a slightly bent position.
- Elbow placement Ensure that your elbow remains elevated and does not droop. Proper elbow positioning is critical for the alignment of the chisel head and hammer face.
- Continuous observation Consistently look at the chisel head during your work to maintain accuracy.
- Handle length Holding the hammer handle too short can disrupt the proper function of centrifugal force and handle flexing.
- Chisel length Using a chisel that is too short makes it difficult to strike the chisel head accurately.
Precision Matters
- To achieve precision in your work, it's recommended to cut at a width of about 0.02 inches (0.5mm).
- Accurately adjusted chisels can process straight, ensuring that your final product is of high quality.
Hammer Selection
- In Japanese furniture making, various hammers are used depending on the specific task. Choosing the right hammer for the job is essential for efficient and accurate processing.

In conclusion, using the Genno (Chisel Hammer) effectively in Japanese furniture making requires a combination of proper posture, grip, and striking techniques. Avoiding common mistakes and paying attention to precision are key to achieving excellent craftsmanship. By following these guidelines, you can elevate your skills and create beautiful Japanese furniture with confidence.
