How To: Silver Blade Collar Fabrication

A simple way to dress up a blade and make a nice transition into the guard.

#1. Notch silver with a corner of a square needle file.

#2. Bend at notches.

#3. Flux and solder. (high temp., silver solder granules and Wolverine Ultra Flux silver brazing flux)

#4. Check fit.

#5. Solder end piece in.

#6. Trim.

#7. File and clean up.

#8. Here’s a couple shots of the finished knife.

  1. So on the soldering you really have to get a solid complete solder so it dosn't show any cracking or breaks in the solder when you file it huh? is there a way to tell how much solder to use so you get it completely sealed?
    or is it just experience?

  2. Good question.

    The most important thing is that the seams be tight and the surfaces touch before you silver solder/braze. It takes some experience to judge how much silver solder to use. If you don't use enough, you get voids. If you use too much you have more clean up work. However, it is usually easier to file off the excess than to go back and try to fill pockets or voids. It's also a good idea to try and place the seams in areas where they will be the least noticeable, not like right in the middle of the "audience side", but sort of tucked away. The silver solder will patina slightly different that the sterling. Of the 3 grades of silver solder, "hard" (the highest temperature solder) is the most pure and will show the least.
