The knife man is very special and every kitchen would be improved with the addition of a voodoo knife block. There are now two versions of the voodoo knife block. The newest iteration (referred to as the 2nd Generation) has a higher quality of knife. You can read more about the differences on the UK site voodooknifeblock.eu although the best prices are more likely to be found via a search and comparison rather than going straight to the official site.
The colour choice has also been reduced to the simple red/black or white, although if you were to look hard enough you will still be able to find some of the older colours of the knife holder available new in the UK.
