Celluloid end date?

[Will Power]

GEC used a Casein based plastic in the early days on a run of 73s or 23s I believe, but they did not persist with it.

No Cell used by them as far as I've heard.

I have several French Ivory knives, that show no signs of deterioration. Maybe it was processed differently from more colorful examples!!

Might also be casein, not celluloid.

Does Casein have "lines/layers" in it like french Ivory??

Yes it does, Charlie, looks more like ivory than some ivory does!

With the half dozen of each examples I've owned and handled the 1970s-'80s German celluloid outgassed much sooner and more violently than my much older American made stuff from Schrade and Robeson. I've always figured that if a knife was 80 years old and hadn't outgassed, then it probably wasn't going to.

Love this one ;-)
