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!
@@bushcraftcostarica808costa rica high moisture dont like carbon steel and me i dont like rat tail tang knives. A combination of both = 100% disaster.
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.
I love your story and the value the knife has to you brother put a hickory spacer and leather washer between the stag and guard that looks the best cool video bro love 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!
I know it’s going to come out good. A bit dissapointed in Randall’s reaction, especially for a company that has been around decades and has a 6+ yr wait.
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.
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).
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
@@bushcraftcostarica808 I was a custom knife maker for a few years and one of my mentors told me about being careful using dissimilar metals in a knife especially with carbon tool steel … it’s not as big a deal in stainless
@@bushcraftcostarica808 yeah I had one that I carried for a while in Iraq… But when I went to Kuwait it was so humid that it kept completely rusting… I replaced it with a Cold Steel R1 … It’s a licensed copy of the model one but in stainless steel and Micarta
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.
@@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.
The stainless steel ones are way more prone to brake! Carbon is always the way to go! I own three model 1s! Two 7 inch blades one 8 inch blade! One Stag and two leather stacked handles! Interesting video!
I did a post on this at BCUSA and it seems very rare. It's got a lot to do with the method of construction, brass, steel, aluminum and leather basically started a chemical process that caused the rust. The sucky part was the only to tell was a bit of discoloration!
Yeah I actually tried to search the post but failed. What a shame this kind of thing happened but at the end in turned out very cool! Reminds me to the old German hirschfängers with that guard
He bought a used Randall. Carried it and used it like few others for years then Randall gives him a new one and even engraved his name on it for free and your disappointed with Randall? What’s wrong with you ! Where he lives he should have requested stainless.

Awesome idea, thank you!
Great job as turning a bad situation into a great opportunity. Can’t wait to see the final results.
Thanks Bob, I am definitely excited too!

Thank you 👍
I’m grinning! That is going to be one awesome blade!
Thanks, I hope so too!
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 am really excited to see how it looks when finished. That Fack that a friend had sent it to me years ago is cool too!
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
That's a great idea, it would definitely strengthen the pores!

What unit at 10th Mtn
3rd Battalion, 14th Infantry HHC 11C 81 mortars "Dragon steel" 91-94
I don’t like the response from the company. Shows why US made is not best. Now that they’ve made the sale they don’t care about the customer.
I didn't either but it is was it is. The original was bought off of secondary market and they stood behind it so I really can't complain.
