It's looking increasingly more like someone on eBay ripped you off Stephen. My own experience of Sorby gouges are that they are extremely good, although I did once have a spindle gouge from them that didn't seem to want to holds it's edge. At the time I was turning a lot, and I sharpened away the gouge in about two months. In fairness to Sorby, when I told them the problem they replaced it without hesitation. It's the only instance of a problem I've ever had with a Sorby tool, and I've certainly never had one break on me.
