That's a really nice system for someone who insists on sharpening by hand. I can certainly see where the customers $300 is going. I personally don't get it though. If I'm going to spend $300 on a nice big, heavy sharpening tool, especially one that is designed to be a permanent fixture on my work bench, it needs to be mechanized so that the work gets done FASTER. I can use almost any lansky style system and my results will be just as good, and take me roughly the same amount of time. Or, I can use a cheap 1x30 belt grinder with a cheap speed control, and get that same result in a fraction of the time, still spend less than $100 AND have a very functional belt grinder to use for other purposes.
