Single-edged blades with a ridge

Offhand, I can't think of it occurring elsewhere, but it's early, and my coffee has not hit my brain yet.

While Most of the examples with t-spines mentioned in this thread I agree are likely derived from Turkic blades (I think they appear on Ottoman Palas in the 17th century) I remembered an interesting much earlier example that I had to dig through my old pictures to find. I found this knife in a museum here in Germany, unfortunately I cannot recall anymore which museum exactly. With a bit of taper at the forte this could pass for a crude Afghan Peshkabz, but it was excavated in a local celtic burial mound dated to 600 to 500 BCE! Doesn't seem that the design really took hold back then, I haven't seen any other examples.
