How to bring things together ...
Back in the days of old, Merkur produced quite a number of different slants. Besides the well known 37 and 39, there were tilted non torqued ones like the B3 and 75, and torqued ones like the 36 (thin handle three-piece) end the 38 (thin handle two-piece). The 38 name has meanwhile been reused for a "regular" razor.
Also, looking at torqued slants, for some most were slanted top left to bottom right. Merkur, Fasan, Valencia, ATT, all slanted this way. Exception: the Ibsen-type slants. Basically two models sharing the same head, fat handle two piece, or short screw three piece. Sold as Ibsen, Liese, Geniol, ... Sounds like a lot of brands, but they were basically all the same razor, whre Merkur, Fasan, ATT etc are all different takes on the slant.
For some reason, when Merkur started producing their "Superslant" (a monniker never used by themselves), they had one "hybrid" model. Hybrid as in: very much like the former 38: scalloping unlike their other superslants yet like the "ordinary" range of Merkur slants and thin handle two-piece, yet more slanted, and torqued the Ibsen way, also the other way around from all other Merkur slants.
Shaved with this today. Lovely shave. Just lovely.
