Hi guys,

I got a new Case Sodbuster Yellow synthetic handle CV. Now I ask myself which handle material is the "synthetic"? Is it ordinary plastic or some kind of G10? It isn´t any kind of micarta. I know that material.

I hope some of you guys know more about that material...

Kind regards...
 
Not sure of the chemistry, but yellow handles have a big chemistry on me:D:thumbup: Buck, Rough Rider,Camillus, Böker all have fine yellows but for me, CASE is THE yellow handle. DELRIN tough plastic.

Hope you get a more scientific answer:D:thumbup:
 
Good question. I don't think it is delrin. Feels different. I looked it up, but couldn't find the answer. Some kind of secret polymer? ;)
 
On the assumption it might be Delrin, even if it doesn't look like it, it may still be. Delrin (as named) has been around for a long time (since the '50s, I think). It's undergone a lot of changes & recipe tweaks in that time. Even today, there are multiple different grades of it, depending upon the intended application. So, it might still be Delrin, but maybe just a different flavor of it, so to speak.
 
Delrin has been the primary synthetic for decades, but recently theres been a number of acrylic handle materials available. GEC has been using it quite a bit, maybe Case is moving there too?
 
this is a very good question, perhaps and email to case to know for sure, it seems like i've only heard the black called delrin, but maybe i just wasn't paying attention. whatever the case yella is made from i like it.

those case yella sodbusters are awesome, i love mine ( i'm a bit of a soddie fanatic) i just picked up a case image handled yella jr.

thanks

I'm not sure just what the material is.

Not real sure I want to know. Maybe it's best some mystery remains in life.

I've had yella sodbusters, and yella peanuts, and they looked good, felt good, and worked good. That's good enough for this child.:D

I was just looking at Case's web site, and they do offer at least one line of knives with what they specifically reference as Delrin (new 'SparXX' line, w/white jigged Delrin). On the other hand, they don't make such a specific reference in their descriptions of the yellow knives (just called 'synthetic' :confused:).

So, who knows...

carl,

in a couple of weeks when get a a bit more play money put up i'm goin back to the chicago cutlery in my area and picking up a yella peanut. i love the yellow and peanuts are good for so many things. and i'm with you that they look good and feel good and they work so i don't much care what it is.

thanks

G10, it is not. G10, by specification requirement, is layers of woven glass cloth impregnated with epoxy. There is no fiber reinforcement in the yellow handles and I am quite certain the resin is not epoxy. Unreinforced epoxy would not be a particularly good choice for a knife handle. It is not tough enough.

"ordinary plastic" is not a good description, as that would include many plastics that are not suitable for a knife handle, nor for much else that requires durability.

I don't know exactly which thermoplastic Case uses these days. There are many suitable plastics from which to choose. I find the Case plastic of my sodbuster to be suitably robust. Whatever it is, they chose it well.
 
Those yellow Case scales seem to be iconic and appealing. Good question about the actual material. I've had my eye on the yellow synthetic handle Case trapper for a little while now.
 
Buck uses a new material in its black sawcut scales. Valox -

BUT, the new model smooth yellows still use good ole Delrin, keeping the tie to my ole black sawcut 300s alive....

Twist my arm and make me guess of yellow Cases, I will have to go with Delrin also. But it looks a little different than Bucks material.

I have some case yellow handle material that I got from Charlie Jones who was a authorize Case Repair Station - they had repair stations back in the day - I have re-handled a few knives with the stuff. Smell’s just like plastic when I ground it. I might have 2 or 3 pair left if anyone ever needs some. This is very old new stock. Tom Hudson
 
Well, after all of your interessting answers I got a little recherche at the internet.

Here´s some kind of identification of that material http://en.wikipedia.org/wiki/Polyoxymethylene

Seems to be a real tough material with a lot of restances... What do you guys think about this chemical material??

Kind regards..

P.S. I had to read the article in german language, couldn´t understand the english translation.

Me to. I find myself looking for more yellow handles.

If it is not Delrin, it is probably the acetal copolymer (Delrin is acetal homopolymer) which has similar properties to delrin with improvements in temperature resistance and better strength in higher temperatures, but lower strength at normal temperatures. Delrin has higher abrasion resistance, so the copolymer version would be easier to finish. Valox is polybutylene terephthalate which is very similar to PET (Mylar). So, Valox and Delrin are different materials, but both have properties that make for good durable knife handles for working knives.
