i bought my titanium coated Space Case like 10 years ago and have not had a single one of these issues. i dont ever need to scrape the teeth, soak it, etc. I also have a graveyard of broken or damaged cheap grinders from the years before that, that i never got around to throwing away. My cheap old sharpstone would get stuck every now and then, id just punch it with a hammer-fist and slam the threads back into alignment. Sometimes you just gotta think like a neanderthal and punch stuff. Looks like they have a lifetime warranty, have you contacted them?
