Not sure that these are what you want, but Menards has this thingee in the grill section- a rectangular base that holds the kebabs and keeps them slightly off the grill. It makes them easier to turn, I suppose. The box includes several skewers of the flat blade variety. Not sure of the cost - maybe $5. I tried it once but thought the meat was too far from the grill - maybe I needed larger chunks of meat, lol. It was easy to turn, though. It may be a dash expensive to buy this item of nebulous function just to get several flat skewers

But, to me, it's so close, I don't have to spend any gas money to go find them.
