and to finally hammer a stake through the "all messers are constructed with knife handles" heart, here is one last langes messer, photographed by Roland Warzecha, from his "Dimicator" pages. as you can see this is a whittle tang, with the stub of a nagel just visible on the crossguard - very definitely a messer, but very clearly not a scale tang construction.
So there you go, you "absolute tourist", confidently making statements which are in fact, completely wrong. Hope you've learnt something. Maybe you'll shock me and say "sorry, I was wrong".
Go on, try it.
