• Artisan Breads: Capable of slicing soft-crust brioche and challah without compressing the crumb structure.

Expert Maintenance & Safety Guidelines

• Hand Wash Only: High-heat dishwashers will dehydrate the modified maple handle and eventually cause checking (cracking). Clean with warm soapy water and dry immediately.
• Wood Care: Periodically treat the handle with food-grade mineral oil to preserve the grain’s moisture barrier and natural luster.
• Sharpening: While the scalloped edge requires less frequent honing, use a ceramic rod to touch up the back-side of the scallops if the 'bite' begins to diminish over years of use.
