Coyote Landscape Products5 Piece of No.4 Rebar, 1/2" x 6' x 72"

could i use these for strongman training like bending them with my bare hands?

Is either side pointy?

What size diameter rebar do i need to put rebar inside a 3/4 pvc pipe

Are the pieces straight? The last time I bought them, long ago, they had "circle loops" in them, which meant I could not fit them through pipes.
