Some things we do know, the inside curve of the hook might be a blade of some sort, you can kinda see it from the way it slopes similar to the blades on our vehicles. In contrast the spikes on the outside aren't sharp and are instead a little rounded/roughened.
Otherwise it looks very similar to Roadhog's Mako Skin Hook from Overwatch. But all metal instead of shark teeth. I will also join the party that thinks it looks just like the hook from the Wracks box
If we could see the handle, we'd be able to confirm if it's the same classic DE melee weapon handle that we all know and love. Alas...
