FWIW, I bet (I may be wrong) that the Pike Swaty was made by Swaty and imported with the Pike name added. Just a suspicion as I've never had one to compare to the Austrian marked hone.
Here is a set of instructions that Swaty sent out with their hones. The barber I knew many years ago would refresh an edge on his Swaty dry. I've been fooling with a few different barber hones here lately and I have been using them dry with few strokes and good results.
When I first started honing on a Norton starter set I would use my Swaty with water following the 4/8 and I got good results with that as well. Using it as if it was a 12k. Not that it is but that is what some said on the forum at that time.
