How to attach brass back strip?


Carl Brill

Recommended Posts

Hi, I'm wondering how folks go about attaching back strips to the spines of bowies and other knives. I've seen them riveted on but more of them are not riveted. So are they sweated on? or you could cut longitudinal grooves on either side of the spine and peen the strip into the grooves before dressing it back....? I dunno.

I did six different searches here on the forum so either I don't understand the search or it's so obvious that no one talks about it....?

Thanks!

Thanks Alan. Might the procedure be to tin the inside of the strip and the spine, assemble and heat? I guess keeping the edge in water to keep it cool? It just occured to me that if your back was soft enough you could drill and tap a few screws vertically down into the blade, a couple threads and turn the threads off the part that sticks out and use those as rivets, through the spine of the spine as it were. A thousand ways to kin a scat.

That's it exactly, tin the strip (and the spine if you want), assemble and heat the blade with the edge in water until you see the solder flash.  Scrape off any excess, and you're done!  It won't take much at all.  As in, tin the strip and wipe it out with a Q-tip while it's still liquid.  A thin film is all you need if you have good contact.

Brass screws would work, as would blind rivets in an inverted cone-shaped hole, a mini-foxtail wedge, a side-to-side through-rivet, whatever works.  Even (gasp!) epoxy or a structural adhesive like Loctite speedbonder 330.  If it holds your rearview mirror on for 40 years at a time it's pretty good stuff...

Before you apply the heat, take some white out and paint the blade at the edge of the Brass along the entire length, This will keep the solder from running onto the blade. It just washes off with acetone afterwards.

The idea, supposedly, is to use the soft brass to catch the edge of your opponent's blade.  How this helps you with a bowie is questionable, since your other hand is probably empty.  They first show up on Scottish dirks, and the idea there is you have a shield with a big spike in the middle that you use to deflate your opponent.  

The usual place they appear is on reproductions of the Musso bowie, the only bowie I know of that had it.  It took all Chuck Burrows could do to convince me it's real.  I've seen two dirks that have one.

Catching or blocking a blade on the spine of a knife seems to be an awkward technique. If you're holding the spine indexed toward yourself you would have to bring your hand all the way across your body to have the spine exposed. But I guess the strip overlaps the sides of the spine so you could catch your opponent's edge with a little angle of your knife as you backhand parry or something?

At least they look nice sometimes

The whole idea of parrying a knife with a knife strikes me as unlikely.  Even the HEMA sword and dagger fencers use the dagger either to catch a bound blade, or as a secondary attack or parry on closing.  Knife fighting is too fast, IMHO, to count on being able to parry, blade to blade.

So, just for the record: the fact that it does work still should not be taken as definitive proof that you are not crazy.

I want that knife to look so good you just have to pick it up, feel so good in your hand you can't wait to try it, and once you use it, you never want to put it down ! If I capture those three factors in each knife I build, I am assured the knife will become a piece that is used and treasured by its owner! ~~~ C Craft

A long time ago a bladesmith had a really nice knife in the works, and then goofed at the very end causing a big flaw along the spine.

"Dang!' thought the Smith as he pondered how to save the piece.

"I know" he said.  I'll put a decorative brass element along the spine to cover up the flaw.

Then again, maybe there was a real reason...

Is this what happens if you lose?

Maybe he's actually planning for a WWE move, like picking him up and throwing him backwards, or a takedown... But where's that dudes pants?

They really weren't great at drawing things in perspective.  Though you can tell his pants and the opponent's shirt used to be pink/red.  A few hundred years worth of ink fading going on.  It is rather surprising how many sword techniques finish with something along the lines of "then move into wrestling to finish him".  In this case he is indeed supposed to throw him (either a tackle or suplex), as described in the text accompanying the image.  

 A good device for a strong man. When you bind with someone upon the sword. Act as if you wish to wind into his face and shove firmly with your cross upon his sword and raise high and allow your sword to fall over your head and fall to him below around both feet, as is pictured here. Thus, you throw him.  

In short:  Blame the illustrator, not the instructor.  ;)

 I suspect that particular technique was forgotten because it generally sucked.

Attack a little lower with your hands behind  his knees, push him over with your shoulder against his hip, and use the time it takes for him to recover to regain your sword and attack.
