I've had this razor about 10 years now and for many of those years it was my only DE razor. I brought it out of hibernation a few weeks back and have been using it for trimming around my beard. This morning, while shaving I felt the faux ivory "sleeve" twist slightly. Not a good thing! In the attached pic, you can see a small crack just under the collar by the first G of Jagger. That crack has been there for years. I'm thinking now that over the years water had seeped in and dissolved whatever adhesive was used to adhere the sleeve to the handle shaft. To my eye, it doesn't look like the handle can be taken apart and I'm not sure the sleeves are sold separately anyway. Would one of Italian Barber's or Maggards handle fit the old workhorse? Thanks in advance!
