Hardwood species most commonly used for my wooden kitchen utensils:
Ash – The sapwood is light-colored to nearly white and the heartwood varies from greyish or light brown to pale yellow streaked with brown.
Birch – Heartwood trends to be a light reddish-brown, with nearly white sapwood.
Black Walnut – The sapwood is creamy white, while the heartwood is light brown to dark chocolate-brown, occasionally with a purplish cast and darker streaks. The wood develops a rich patina that grows more lustrous with age.
Cherry – The heartwood varies from rich red to reddish-brown and will darken with age and on exposure to light. In contrast the sapwood is creamy white.
Maple – The sapwood is creamy white with a slight reddish-brown tinge and the heartwood varies from light to dark reddish-brown. Both sapwood and heartwood can contain pith fleck.
Hickory – The sapwood is white, tinged with inconspicuous fine brown lines while the heartwood is pale to reddish-brown.
