I've owned my Brothers of Bushcraft Fieldcraft for about a year now. I've never been a fan of the shango notch for use with a ferro rod, as I have several other objects I can use to throw sparks. Even my Bushlore does a decent job with it's spine. Some people claim that you should just merely Dremel off the spine to a 90° on the Fieldcraft, but I was informed this will slightly affect the strength of the knife, due to the way it's heat treated, etc. So rather than do that, I did finally find a pretty decent method that actually works pretty well. Not sure why TOPS wouldn't have shown this method to all of those that complain about the shango notch. Here's a quick video:
