I've been looking for an open comb slant for awhile, finally found one on the bay and received it a couple of days ago. It's agressive, but not overly aggressive, with a nice tactile feel. Very maneuverable around my chin and nose. 3-pass shave was BBS. I'm using Perma-Sharp blades but will experiment with others.
Definitely a keeper.
Sorry for the low quality of these images, but you get the idea. The barrel says "Made in Germany". Don't know if was made by Merkur or someone else.
