Thank you, everybody.
Claude, the buckle is heavy, solid brass. The tongue, or tang, looks a little stumpy, but please don't let that fool you. These buckles are HEAVY, and they'll take more stress, and more abuse than any other buckle out there that I'm aware of. That's one of the reasons I'm partial to them. Plus, they look good.
The other thing I like about this buckle set is that there's no need for a slot to be cut into the belt itself. Standard buckles require a slot cut for installation. If you don't cut the slot, then you have less lateral twist potential. You maintain 100% of the belt width throughout, versus cutting out 10% for a slot.
