 Thanks! Your persian dagger is beautiful, Im putting one of those on the want list. As for light patches, yes most likley heat treatment. I have started to realize that once you have found the correct etchant for a specific blade, its best to just accept the result, any discolorizion on the blade, from heat treatment or other is part of the blades personality.
