Check out some old lee priest articles on forearm training. He trained the dog shit out of them constantly and he had prob the best forearms in the business.

One thing a lot of people forget is the forearms do supination as well as flexion end extension. A good way to work supination for wrist development is Sledge Hammer Levering. This involves gripping a sledge by the handle and then lifting the head up and down, under control, using wrist strength. 4 directions, front, back, and each side. Here is a good video showing the different methods.

Side to side is not shown but same idea as front and rear just holding the sledge out to the side and twisting the wrist to raise the hammer.

Also avoid using lifting straps during Deadlifts.
