This Umebachi Ryuma 42mm woodworking plane is a traditional Japanese-style kanna designed for accurate smoothing and fine finishing of wood surfaces. Its blade is hand-forged from SK-5 high-carbon steel laminated to a soft iron backing—an approach that places the hard steel at the cutting edge for excellent sharpness and edge retention, while the softer iron provides structural support, eases sharpening, and helps absorb stress during use to reduce brittleness.

The plane body is crafted from white oak, prized for its density, stability, and long-term resistance to warping. Compact in form and finely balanced, this kanna offers reliable control and clean finish quality, making it a trusted tool for carpenters and dedicated woodworkers seeking traditional performance with modern consistency.

Suited for professional joinery, furniture making, and general carpentry work, this kanna is also ideal for planing narrow wood stock, chamfering edges, or cleaning up surfaces after saw cuts. It can also be used in DIY home woodworking tasks where smoothness and fit are essential.

Product Data:
• Approximate Dimensions: Width 55mm x Height 180mm x Depth 45mm
• Blade Width: 42mm
• Body Length: 180mm
• Material: White Oak body
• Blade Material: SK-5 Steel on soft iron blade
• Weight: Approx. 350g

To use, adjust the blade depth by tapping the top of the blade or the rear of the wooden body until it just protrudes from the sole. Hold the plane at a consistent angle and draw it along the wood surface with even strokes. Always work with the grain where possible for best results.

Keep the blade oiled when not in use to prevent rust. Store the plane in a dry place and avoid leaving the blade in contact with other metal or hard surfaces to preserve the cutting edge. Do not strike the plane aggressively when adjusting; small taps are sufficient for fine-tuning.
