KAKURI Genno Japanese Carpenter Hammer 10.5 oz – Wood Handle, Double-Faced, Made in Japan

Meet the KAKURI Genno hammer, a purpose-built Japanese carpentry tool designed to support precise adjustments, chiseling, and nail driving. Handcrafted in Japan, this genno hammer blends traditional craftsmanship with modern durability to assist both beginners and seasoned woodworkers on real projects.

Its double-faced head is the core of its versatility. Start nails with the flat face for a clean initial set, then switch to the slightly domed surface to finish without marring the wood. This thoughtful design helps maintain smooth surfaces and reduces the need for post-work touch-ups, especially on soft woods or delicate joinery.

Durable build you can trust

The Genno hammer pairs a robust Japanese carbon steel head with a wedged attachment to the natural oak wooden handle. This creates a secure, long-lasting connection that resists looseness during repeated strikes. The head’s weight, balanced around a compact 300 g (10.5 oz) core, supports controlled tapping without overworking your wrist, while the overall weight aids progressive driving through a variety of nail sizes.

• High-quality carbon steel head for durability and consistent performance
• Two working faces: flat for starting and domed for finishing with minimal surface damage
• Wedged head-to-handle construction to enhance rigidity and longevity

The handle is crafted from natural Japanese oak, offering a comfortable grip with a solid feel that fits naturally in hand during long sessions. The wood’s smooth finish provides a reliable, secure hold even when your work requires precision and gentle control. This blend of materials reflects KAKURI’s commitment to traditional Japanese toolmaking and practical, real-world use.

• Natural oak wood handle with a comfortable, secure grip
• Timely, balanced weight for both accuracy and stamina
• Made in Japan with craftsmanship from skilled artisans

Whether you’re adjusting planes, chiseling fine details, or starting nails, the Genno hammer offers options that can help you approach tasks with confidence. It’s designed to be approachable for newcomers while still delivering the reliability and control professionals expect from a Japanese carpentry hammer. As with any tool, results depend on technique and context, but you may notice smoother nail starts, steadier chiseling, and better surface integrity when used thoughtfully on projects that matter to you.

In short, the KAKURI Genno hammer is a thoughtfully engineered addition to a woodworker’s toolkit. It emphasizes dependable performance, comfortable handling, and a design language rooted in Japanese woodworking tradition, all aimed at helping you work with clarity and control on a range of tasks from quick fixes to longer builds.
