I use a magnetic knife holder in my kitchen and love it, and I can’t believe no one has thought to make a wooden version before (that I know of, anyway). From the site:
Strong magnets hide inside a striking piece of reclaimed, old-growth Cypress. The wood selected for our knife holder was milled from early 20th Century water towers built in Chicago.
Very handsome. A little pricey at $125, but a good idea nonetheless. [Design Milk]
