The Becken premium knife roll is a professional chef knife bag designed with toughness, durability and functionality as well as character and style to create a timeless and beautiful roll that you will carry with pride. Waxed canvas is breathable and water resistant. Over time it will develop a patina that will bring out the unique characteristics and qualities in the fabric, much like leather. Waxed canvas doesn't require regular cleaning. When you do need to clean, you can use a dry brush then lightly scrub using a cold damp cloth. Do not use harsh detergents, hot water or dry clean as it can strip the wax from the canvas.
