Are these mono or poly crystalline diamonds?

Ultra Sharp Sharpeners are made of micronized monocrystalline diamonds which results in faster sharpening speeds and greater durability than fragmented polycrystalline diamonds.The key aspects of Ultra Sharp stones are the quality of the diamonds, the carefully graded particle size, and the dense, even distribution of the diamonds on the stones. This combination of features makes the stones consistently reliable, durable and an exceptional value.

what is the base made from? Nickel? And could i use Trend abrasive lapping fluid?

The base is made from nickle-plated steel. The best lubricant to use for diamond stones is Krud Kutter. Krud Kutter is inexpensive and can be found at most hardware stores. Windex or any all-purpose cleaner like Fantastic, Formula 409 ect all work well but Krud Kutter is the best. You can use an expensive lapping fluid but these are much cheaper options that work just as good or better.

Why does this set cost so much more than the ultra sharp ii set?

This set is 8 x 3 inches and includes the Universal Stone Holder. The Ultra Sharp II set is 6 x 2 inches and does not include a stone holder.

Where are these made, usa, china?

Being as anything about where these stones are from has been rather elusive and it's not on the package or stones anywhere(that's a first) I'm going to say it's safe to assume China.
