I am back making knives after a bit of a hiatus. I just watched a video by Zac Buchanan illustrating his technique to solder stainless guards. Really nice video. He was using the above mentioned solder paste and said it was a bit spendy. I have been searching the internet and local suppliers and can't find a jar of the stuff he uses for sale. Does anyone know how I can get it? I have always had trouble soldering stainless guards to my blades and thought this just might be my new technique.
 
All you need is Stay Clean flux and 4% silver solder.
Clean the parts to bright metal (abrasive, not washing) immediately before soldering. Heat the largest piece first and flow the solder. As soon as it flows, remove heat.
 
I typed in Castolin 157 and got multiple hits ... including Castolin's website where all their soldering and brazing products are listed. You might try them.
 
I got hold of the Castolin dealership in Wisconsin and worked with a very helpful guy named John Heibler. He set me up and I ordered a jar and saved a bunch of cash to boot. Thanks for the input. I am looking forward to winning my battle with soldering stainless guards.
