Jedd released his Bending eBook right when I was getting into serious grip training again, so ofcourse, I had to check it out. I don't think anyone has ever written about short steel bending in such depth. He covers not only the different styles & grips used but also different types of steel, nails, bolts, etc. He really gives you everything you need to know to get you started bending steel.
I'm not completely wet behind the ear when it comes to bending. Short bar bending was contested at 3 grip contests I've competed in. Not one of my stronger events but I have worked my way up to bending a respectable 6" grade 5 bolt (rated at 345lbs) and I have spent plenty of time on the Gripboard reading about bending. So even though I already knew some of the stuff presented in Jedd's book, it was nice to have it all in one simple, easy to read package without having to sort through pages of bending vs folding arguments.
Of course, Jedd is a far more accomplished grip athlete than myself. He's miles ahead of me when it comes to hand strength but what I didn't realize is how much more advanced his understanding of grip, bending in particular, is than mine. I definitely picked up some useful tips from the Diesel Bending book. I would definitely recommend this book to anyone, beginning or advanced, who has an interest in bending short steel.
