The dark knife rack is made from Wenge with a thin sliver of zebra wood covering each of the six 3/4” diameter rare earth magnets I epoxied. The lighter one is Bocote with yellowheart covering the magnets. Each one was finished with butcher bloc oil. I covered each magnet with a contrasting wood to add some flair but also to avoid having the knife blade touch the magnet directly and get scratched. The rare earth magnets are strong enough to hold a variety of chef knife sizes and you simply touch the blade to a “button” and it stays.
