"I'm not saying that such machines can't be built for razors. But as I said, it would be a huge investment up front.
And make no mistake, prices are 'high' because there is no supply. If the prices would be subject to agressive competition, they would fall and the market is so small that any profit would quickly fade away to break even at best.

If Dovo and TI were not in a sellers market, their razor business would be killed overnight."

This pretty much sums it up, IMO.
