I don't want this to become a heated debate, it's just an observation and maybe something few have tried.
In regards to the one stick fire method (which I've used a variation of for some time) part of the process involves making scrapings for tinder. I'm not one to drag a knife edge perpendicular to anything, leaving the use of the spine for scrapings. Many knives don't have a sharp enough spine to make scrapings, which brings me to the topic of this thread.
Next time you're out, if you have a blade with serrations take it with you and try the serrations. They make great scrapings, sometimes you can almost get a fine curly thread even. Since it's along the lines of a chisel grind, you may have to switch it over to your other hand depending on your technique, but the serrations have great use in this application and saves your edge.
Give it a whirl and see what you think...maybe you'll not hate that knife you've had for so long, but don't use. Some of the production folders we carry have a hidden function many overlook.
I put this here because it doesn't really fit in any one tool category, but if you want to move it please do so.
