I bought these hoping they would work with Morezmore Modular Armature. I could separate them, but I couldn't bring them back together. No matter how aggressive I am. The Morezmore token tongs they sell for this rebar are double the price for the same function so I took a chance and grabbed a 1/4" it works great. They don't separate them but I didn't have one I still wish I would take it apart for more accuracy, but I'm sure I'll find another way anyway.
