super glue and sealing the guard on partial-tail knives.

No big deal, not rocket science or metallurgy, and I'm probably the last person on the planet who thought of this: I use knives (puukkos) where the seal between the guard and the blade is not perfect. I seal the gaps by dripping super glue into them until they're filled. Blood, grease, oil then cannot get into the guard and I can be sure the knife is thoroughly clean when I clean it.
 
Super glue or epoxy (alone or mixed with an additive) isn't a bad fix, and has been used for years. Granted re-fitting, or the second best option - silver soldering is a cleaner looking option, but not always feasible.
 
epoxy is more what I was thinking just name/term was escaping me mostly as they might be better designed to adhere to the materials and/or resist the environment. I was also thinking how super glue tends to leave that ugly white look on places where it dries.
 
I pull them apart, clean and dry them, sand off the crud, then make sure to completely fill the void and junction with epoxy. Lots of people on this forum do this.
 
I've used epoxy for this for a long time. Works great. It can also be colored with plastic model paint; just a drop mixed in AFTER the epoxy is mixed. I tape off areas around the blade and/or ferrule and use a little Vaseline to prevent the epoxy from sticking where I don't want it.

Epoxy it is, then! Next time I'll use that. Superglue is convenient and cheap, though, and with a little care leaves no trace.
 
You guys have an easy way to disassemble these with basic and tools? I have a mora 137 I’ve always wanted to rework.
 
I did this by placing the Mora (number 1) in a vise blade down. You'll want to wrap the blade in painter's tape first. The vise need to be loose so the blade isn't clamped, but rests on the bolster/guard. If it's a full tang, I just used a center punch and hammer and drove the blade out. If it's a partial tang, you'll probably have to drill down through the handle to the tang first. Be careful of your feet, and have something to catch it when it falls out like a plastic wastecan with a couple towels in it, or something like that. Go easy on the punch, it's pretty easy to split the handle completely in half. If that happens, you have epoxy, and you can just glue it back together. Once it's out, it's a simple process to clean and fill the void with epoxy. You can drive the ferrule back on with a hammer, blade tip down on a 2 x 4.
