Well, there is no bolster on that knife. By "extra hump" I mean a blade shape similar to that of the SOG Stingray or Tomcat. Those kinda have "two swedges" and on the Spydie, the top of the latter (if the first is near the tip) "swedge" makes a pointy "hump". It looks a bit like the hump on the REKAT Escalator, but it's smaller and pointier. I hope this makes any sense, I´m in school now and I´m tired and my back hurts, so please forgive me the cryptic language.
Sal, I don´t think I saw anything on the blade tang, but I´ll look again when I get home. I might get it scanned here in school, but can´t say it for sure yet.
