So I tried the Yagi slant plate on a SS Ikon handle. The blade is Astra SP second shave. After a good prep I did a 2 pass shave with some buffing. I agree with the previous posts: the blade is not held well, lots of blade chatter and skipping. No nicks, no irritation but I get closer shaves from me new Shave It razor that is milder. I have to try different angles but I was expecting a closer shave and more rigid blade holding from this razor. I have to revisit my Mercur 37c to compare. I don’t regret buying the plate, I may try it again.
