Source for 3/4″ metal G-hook?

3/4" appear tough to find. All I came up with are bra hooks

Or you could buy these Sea to Summit straps and take off the hook. Not quite as low profile as the one in your pic though

Maybe have them made by someone like Ponoko? (http://www.ponoko.com/laser-cutting)

Think laterally. Search on suspender hooks. eBay have them:

and

Added lettering to the latter and they would look like the Arcterix ones.

Cheers

I actually literally did a google image search for "suspenders hooks" yesterday before you posted, and didn't come up with much. That latter ebay link looks good. But that's basically about the only thing on offer so far.

Thanks guys.
