Most welcome.
Especially because you knew what was going on with the spring, when I didn't! I found that razor to be shockingly mild (contrary to its reputation) though I still liked it just fine -- I had to do full three passes and touch ups to get close; but it was always a "safe" shave. I wished it were more aggressive. Now I learned from you that it... is!
The Gem Jr. tonight again, for me. Thanks for that! I think it feels, in the shave, very much like the Feather Weight slim head; but it shaves closer, easier. It was perfect for tonight's head shave.
(Last time I shaved my head, I kind of "forgot" how to treat the Gem OCMM; that had been a favorite head shaver, but... I'd been using a 1924 or a 1912 for a while, and didn't treat the OCMM and the brand-new PTFE blade with enough respect. Bloody towels resulted. So tonight, the Gem Jr.... NO worries about cuts or weepers... still a close shave... very comfortable!)
