Lew,this is for you!
The three on the left are new arrivals, the others I have shared before. The two on the far left are better than average examples. They both have grips wrapped in silver wire. The 2nd from the left was very dirty and cleaned up well. However, I wonder if possibly it has had a "new" blade at some point. The blade is not near the quality of the one on the left, or even the rest of the dagger itself, and the peen at the top of the pommel ends too far out from the top - should have inlcuded a pic, maybe later.
Notice the quality in the blade on the far left. I haven't seen an example with a blade like this before. I suspect it was made elsewhere, like so many of the sword blades imported to Abyssinia.
