I don't need a knife block. After seeing my brother's own concoction, I made my own magnetic knife holder with high-powered magnets and some metal rulers. Instead of the usual kind which mounts on the wall, mine's stuck to my refrigerator, out of the way. I don't really cook all that much, so I don't really chop all that much.
So I don't need a knife block at all.
Which doesn't really stop me from deeply wanting this
Too bad they don't actually sell the thing.
