Schrade switchblade celluloid - repair, remold, or replace with a different material

Postby BFORSE » Tue Jul 16, 2019 3:26 pm

I’m new to here and I know that there is a vast amount of knowledge that can be gleaned from those who have experience dealing with this issue.
I have a 3-3/8” schrade double switchblade No. 7404WT Ivory Celluloid handled knife. The blades are fairly decent as far as width, but there is slight peaking on both. The celluloid on the other hand is missing almost half on one side and the other side is cracked all over.
When facing this issue and considering the level of damage I believe that repair is not an option; would one then try to mold new scales from celluloid using a jig of some sort or replace with a new material?
Right now I’m entertaining the thought of creating new scales from Resin-ivory. Would that be considered taboo? Would it negatively affect the value?

I don't think replacing those covers will affect the value that much. It has value as an automatic, if it functions well. However, there is a bit of blade loss and corrosion, so I don't think it will ever command high dollar.

If you can make it functional with decent covers, go for it. You may also want to send it to MuskratMan or Bill DeShivs. Both are great auto repairmen.

Thank you for your response. The way I figured; it started it’s life with fake ivory, why not put fake ivory on it again. And as you pointed out, it’s not a museum quality specimen.
I don’t know if you would know or not, but do either of the gentlemen you mentioned have the ability or tools to create new celluloid scales? Just asking for future reference in case I do happen to run into a museum piece in need.

IMHO, I'd go with white bone, before I put celluloid on it.

BFORSE, you will probably be better off with some other type of handle material. Celluloid degrades over time and outgasses and corrodes the metal parts of the knife. Probably some one will be along to suggest a better solution. By the way, Welcome. Hope you hang around. ::handshake::

Thank you for y’alls input. I agree bone would be a very good option, better than the original celluloid when it comes to corrosion. But because I am somewhat of a perfectionist if I did go back with bone scales, I would have to do my do diligence and research how to dye bone like GEC’s antique yellow and make a tool to recreate a pickbone texture like the attached; I would try my hardest to mimic a No. 7403T...so probably for now I will go the synthetic route unless there is any major reason why that would be a bad idea. If it looks bad I can always start over again.

There are various examples of acrylic plastic materials by several names available. I think the very last celluloid was manufactured and used on knives in Germany some years ago. I don't think the material exists today. Wouldn't be the first time I was wrong.

Thank you tongueriver, I am amazed at how many people have been willing to share their expertise and experience concerning this topic. By the way if anyone could point me in the right direction when it comes to the process and materials needed for dying bone in the likeness of GEC’s antique yellow bone; It would be greatly appreciated. My experience in bone dying is limited to painting it with potassium permanganate. It definitely gave me the brown tones that I was looking for but I think that a yellow undertone would look more period correct.

You may want to try Culpepper's (knifehandles.com), they do a lot of jigging and dyeing of their own bone, and they are who I use for all my bone. You may be able to find something to your liking there.

I have used acrylic or kirinite to replace celluloid. It's probably the closest in appearance.

I’d consider putting ivory micarta on it. Not real expensive, near-indestructible, similar look to the original covers. ::tu::

Well, I went to knifehandles.com....
I ordered some smooth mahogany bone. My plan is to try to replicate a pickbone pattern. I know it will mean more work and risk but when it comes to projects like this, I can’t help myself :wink:
