A question about delrin.

OklaMoose said:
I will also add this, and someone may correct me on it if I am wrong. But if I remember correctly from past research I have done, the "true delrin" of yesteryear is no longer put on the Case yellow handle knives. (Hence Case calling it "Yellow Synthetic" these days). It's still pretty much the same exact thing, just different chemicals and such within the synthetic material, even though we all still call it delrin. Regardless, it is a great material and all of us "yella handle" fans still love it.

(P.s.) I will try to remember where I found the research on that, and post it. If I can find it again.

That's interesting information, I've noticed with a fairly recent CASE Penknife in Yellow D that the scales got stained with black dye when I stored it something. These stains won't come out either.
 
I love delrin but dont try to clean it up or anything on a machine...it melts....or leave it in the sun for a stretch(who does that anyway?)
Pics in the morning...:)
 
Interesting info! Seems to me the new kid on the block is G-10. However, I have a puma sergeant from the late 80's that has a plastic material on the handle that while it isn't exactly G-10, it must be a very close relative. I think it was marketed as indestructible, and I will say it is very tough stuff that still looks the same today as it 30 years ago.

I noticed blue staining on my yellow Barlow. It won't come off either. Been a puzzler since I can't remember doing anything different with it in terms of use or storage from all my other unstained knives, including a couple of other yellow ones.
 
I wonder if Camillus used the term 'staglon®' (it is NOT stagalon) for their knives or if that exact word was only allowed on Uncle Henry knives. I know that Camillus used the term India Stag® for some of their Delrin®. Going way back, along with celluloid, were gutta percha and bakelite. Fosterene in the 1950s. CASE and BOKER have used black synthetics in secret formulae which have probably changed in composition over the years. Fun stuff. Some of the compositions were trade secrets not divulged to this time to the general public.

Camillus had "Cabone" for sure Cal... I know I saw recently what they called their version of the Staglon but I'll have to look for that. Stay tuned ;)

I forgot about gutta percha and there was casein too LoL So much history so little time o_O

Looks like Indian Stag was their version of Staglon back in the day and they later had Dura-Stag :thumbsup:

Real Delrin on the bottom, imitation delrin on the top :rolleyes: ;)
Although I did sand it some to bring out some contrast and to look more like the imitation stuff
:D:thumbsup:

Some bright orange delrin snuck in there to

That picture interests me. The top knife without tang stamps in faux delrin ;) is very much like a Queen Cutlery No.2 Jack I have. It was sold to me as delrin but I found the pores on it to be 'suspicious' and I'm sure it's bone :D I think mine's from about 1976 and I also believe there was a run of Schatt & Morgans at about this time in genuine WB Bone/faux delrin. Think mine was clad in some leftovers :D
