Not Oak as stated, it is a cheap beach wood finish.  Finish is lighter than shown.  Holes in mounting block too small.  Holes on pattern do not align.  Spinning roller assembly has a lot of play so the block remains at a slight angle.  Others have had the wood split with use.  Will not fit a cleaver.  Sharpening steel slot too high up so it will not fit.

Although this idea is good, the premium price and poor quality makes this a poor value.  Very disappointing.

2017 update.  The magnets on one of the slots came out resulting in the knife not staying in place.
