I’ve been bending grab irons for lengths not commercially available and bottom mounted uncoupling levers since DA raised the prices several years ago. I use  Xuron fine nose pliers. Personally, I think that the bending pliers would be very difficult to use for grab irons and uncoupling levers because it would be impossible to make repetitive bends of exactly the same length. The fine tip pliers allow more precision so you can place the bend exactly where you want it.
