I received my full-sized Sword of Omens replica today. It's nice. Couple of small quirks though.
First thing I noticed after removing the shrink-wrap was that mine had been coated in a thick, clear oil (to protect against rusting I guess, which is nice) In washing this off I also realised that my sword had been murderously sharpened!
It's cool and all but as a prop that's only for display, not really necessary. Definitely won't be letting my kids play with this one. Reading back over the eBay listing I note that it says it's "a high carbon double sharpened edge fixed blade". Skeptical on the carbon steel but it's really hard to test that.
Next I noticed that, unlike the OP's sword or the dagger I bought, this is pure shiny stainless, not the slightly darkened/weathered look. Not an issue really, it has enough surface detail on the hilt that I can darken it with a wash to get a similar effect. The listing pics showed the darker colour but they're the same stock pics every listing uses.
The biggest difference is that my sword already has a light-up Eye. The lowest of the gems on the grip has been replaced with a momentary push button and when you press it, the Eye lights up. The pommel unscrews and there's a sealed plastic cylinder inside. For some reason, the batteries are sealed in this plastic cylinder and I can't see how to remove them to swap them out. It's just got two wires running out the end of this battery pack into the crossguard where the light is hidden.
I wasn't planning on lighting this, and was actually going to replace the stock Eye with a 3D-printed one, so this complicates things a bit. It should be relatively easy to remove the plastic battery pack and wire in a rechargeable 18650 Li-Ion and recharge port, but replacing the Eye of Thundera is a little more complicated now. There was no mention of the light up feature in the eBay listing.
The sculpt is a little different to the OP's, and to the Dagger but close enough to work for me. All told, I can definitely recommend these swords as good wall-hanger props, ripe for a little extra customisation.
