This item is being sold as a "defective" product due to the presence of knots and filled-in sections on the back. Apart from that, I believe it's quite well-finished, so I hope it can be used by those who don't mind the back! ✩ Made with certified Fuji Hinoki wood grown in the Fuji area ✩ Of course, a thick, luxurious single board is used ✩ Hand-planed by a professional for excellent water drainage! ☆ You'll be able to feel the difference when it gets wet! ✩ Great for fishing and outdoor activities! It may look simple, but it takes a lot of effort! [Size] WFS1, filled knots on the back, shorter length Length: 331mm Width: 240mm Thickness: 43mm Weight: 1586g ※ All dimensions are approximate due to hand finishing. ※ Because of its thickness, I think you can use it for a long time. [Material] Fuji Hinoki single board ✩ One corner is beveled, making it slightly easier to lift. [Good Points] ✩ I believe that a cutting board is best when it's [unpainted], so I've finished it with a hand plane as a surface treatment to achieve that. The chamfered parts are also finished using well-sharpened blades. First, it's planed, then wetted with water to raise the grain, and then planed again after drying, so the grain raising due to water when in use is minimized. Also, the end grain, which is usually difficult to plane, is also finished with a plane. This allows water to drain away in the shortest amount of time without absorbing the grain or sandpaper scratches, minimizing the deterioration of the wood due to moisture. ✩ Predicting the direction in which the wood will warp, and taking into account the blade contact, it is slightly and gently shaped with an R-shape to match the individuality of the wood. This is also a technique that can only be done by hand planing. ✩ No [sandpaper] is used in the production of the cutting board, so there is no worry of the remaining abrasive particles damaging the knife or eating sandpaper dust. ✩ The rough sandpaper finish that is often seen recently, which looks smooth at first glance, becomes slippery when wet. In contrast, the smooth hand-planed finish remains smooth even when wet and is surprisingly non-slip. It's also fun to touch ✨ The above are the good points.
