I am interesting in buying a single stone to keep my razors touched-up. My question is how do the Swaty hones differ from Chinese 12k stones and vice-versa?

The Swaty hones oven end on eBay for more than I can get a nice Chinese 12k for, so I am curious to entertain this alternative if the results would be similar/better.

I've also heard discussion that Chinese 12k are not really 12k grit, but that they hone like a 12k because of their relative hardness in comparison. IOW they take about as many laps as a 12k would.

Can anybody provide input on the pros/cons for each?

Thanks,

Ogie
