Steel to aluminum contact with moisture causes what's called galvanic reaction. Violent mass oxidation of the metals. Very typical of what you experienced. Same thing happens when you use steel hardware to mount aluminum gutters. Can't wait to see your rebuild!

Thank you, that's it exactly, I couldn't remember the term that the folks on BCUSA told me. I'm really looking forward to stopping the process and putting the blade in a nice, new (and safe) handle!

When you are finished drilling the hole for the tang you can fill the pores in the horn with superglue and then glue it with epoxy

Thanks Bob, I am definitely excited too!

To treat the galvanic effect you are experiencing use a product made by Ideal Co. called NoLox. It’s a grease. Slather no more than 1/64th inch thick of the product on the carbon steel hilt (tang).

Thank you for the info, if I ever run into this problem again that's what I'll use!

I really like what you’re doing with this. I have a suggestion if it ever happens again, soak it in vinegar and give it a nice acid wash or acid patina, and then use clearcoat to seal it. It’s about the only way to protect something in that kind of environment. I don’t have to worry too much about it but when I receive a old knife with carbon steel, the first thing I do is, give it a nice acid bath and a synthetic patina so it doesn’t rust anymore. Then I clearcoat it and rebuild the handle or do whatever else I have to do to repair the knife. It turns the carbon steel black but I think it looks cool.

Awesome idea, thank you!

I know your past this video. But Birchwood Casey, makes a Blue and Rust remover. What you should have done, after cleaning up the tang, would have been to blue it deeply. and maybe get a steel butt cap made. I'm lucky to live in a very dry climate.

That would have probably worked great, I just wasn't sure how well the epoxy would adhere to a blued steel.

@@bushcraftcostarica808 Hm, there is that, but you cut notches into the tang and if you used enough epoxy, it should work fine. Nice job all together on the knife. I have a Kabar with the same kind of tang, but I think its powder coated. Plus the butt cap is steel. Interesting thing is, all my Buck Sheath knives use a aluminum butt cap onto a steel tang. I wonder what they did, too keep corrosion from happening. Any ways, your knife turned out great, just different :) Even if I had the money, I don't think I'll be buying a Randal knife, even if I had the money.

That guard looks good. The Model 1 is the Randall I like the most. I carry a 1-5 in the city and a 1-8 outdoors.

Thanks, I hope so too!

Bi-metallic corrosion… it is an electrically active reaction between the metals… they pass ions between the molecules and they both corrode. Why they would use aluminum as a butt cap is beyond me because this is a well known issue between aluminum and carbon steel. If you want to use the similar metals you absolutely need to completely isolate them from each other so they can’t start the galvanic reaction… sad that such a well respected bunch of knife makers would make such a rookie mistake

I was a bit too, however they did replace the first knife (bought second hand) for free. So they really didn't owe me anything. I'm concerned about the tang transition, that 90° angle... that's exactly where the first one snapped. I was always taught to make it a curve there so that you're not creating a stress point. It's all good though I'm happy with how it's turning out and it's not going to be a heavy use blade anyway.

That’s right on the tang- curved into the tang. I did notice there was a very small curve to each side and I was looking for that. As you said, not a heavy user, so no worries on it.

Very cool backstory, I enjoyed hearing it. My most-used knife in my woodcarving shop is one my mom gifted to me, and I cannot imagine having it fail me. It would be seriously depressing. Like an old friend betraying me somehow. Not really sure why it's like that!
