Celluloid Scales: How Old To Have the Negatives?

[AFAustin]

I have read that celluloid scales can deteriorate, giving off gases that can even harm knives stored close to them. So, it is recommended they be stored separately. I know this is old news to the veterans, but as a new convert to traditionals, it got my attention. But I also seem to recall that the problematic celluloid wasn't produced much after the 1940s.

I happen to have a nice Bulldog trapper, which is described as having red celluloid scales, stamped "1998" (4th generation). So, is this the celluloid with the problems mentioned, or is it really acrylic that is incorrectly described as "celluloid", or is there "new celluloid" as opposed to "old celluloid", or....? Any help would be much appreciated.

Thanks.

From what I've read, celluloid was used on knives even on through the seventies and, even though it's not flammable like the early stuff, it still possesses the risk of decomposition, outgassing, etc. In fact, I'm a little worried about a '71 yellow handled Case stockman I have that may prove to be problematic.

As far as your knife being celluloid or acrylic, someone else will have to chime in that one, sorry.

P.S. This article is worth a read if you haven't already checked it out.

I would be willing to bet that a knife manufactured in 1998 has stable scales.

I would not worry too much about it.

Thanks for the posts. JAB, I appreciate the article cite. I read it with interest.

Bigfattyt, I am also reassured by the fact that there has been no deterioration since 1998---that's got to be a good thing. Still, I will keep my eyes on this one.

Andrew.....

There are many good articles on celluloid and deterioration with a Google search but in the end many will point to the fact that as more and more manufactures entered the market they were all trying to get out a product that could be sold for less...and we know what happens when you skimp on compounds, materials and substitute.......in doing so out gassing was the by product...there are still many celluloid handle knives that are in fantastic condition will they last..don't know....some go fast others last...

As an example Waterfall handle ( celluloid ) materials used by Queen on the Winchester Brand, Fight n' Rooster and Bulldog Brand in 1996 all can show fatigue on the blade.

I have had celluloid manufactured after the year 2000 deteriorate suddenly. And don't believe that it's not flammable - it still is!
I have old Remingtons and Western States from pre-wwII that still appear good, but you will never be sure until it goes off!
The acrylics used lately are supposed to be much more stable.
Avoid celluloid, unless you enjoy the risk.
