Case Delrin Question

[bladeboss]

Howdy folks.

I've been carrying around a Sodbuster lately.
I was wondering how resistant the handles are to chemicals and real-hot water.
I work on cars and trucks and get oil and grease on it.
It would be SUPER easy to me to be able to use something like brake-cleaner or hot water.

Will these handles react with Iso-Alchohol or brake cleaner?
Will they melt easy with hot water?
What about boiling water?
How about the CV steel reacting with the cleaners/alcohol?

Thanks in advance folks.

Delrin (Acetal) is an engineering plastic that is quite advanced. It's very abrasion and chemical resistant. We used to use it a lot when building custom machinery. A lot of plain bearings and other parts that wear against steel are made out of Delrin.

It should be able to take any temperature of water and alcohol is fine. I'd stay away from the stronger solvents (like brake cleaner) to be safe.

Your best bet for cleaning is going to be hot water and dish soap. Just make sure to dry the CV steel and maybe apply a bit of oil to the joint after you wash.

We use delrin extensively at work, we use it inside machines that are subjected to constant exposure of liquid coolants, we clean them with alcohol, but avoid strong solvents as it can degrade delrin (though I doubt it would degrade enough to cause problems with your knife handles, we have extremely tight tolerances on our machines). Avoid acids.
