A few years ago I spotted an unusual folding knife in a junk shop. A plain wooden handle and what appears to be a bronze blade.
Bronze is not really good material for a knife blade, it won't hold an edge and wears out, so it seemed unusual and piqued my interest. I paid a few quid for it.
Why use bronze as a cutting edge? The only thing I could think of was if the user was working in an explosive environment and any spark was an absolute no-no. Something like a powder magazine on shore or ship perhaps? Where they had to open bags of something likely to go bang if a steel knife caused a spark?
I am really open to ideas on this one. My theory of no-spark knife is just that - a theory.
