I have never analyzed Lennie's hand, but more than likely symbolically, the hand represents two things, love and brute strength. Lennie does not know his own strength, and in loving something, his hand cuddles too hard with animals and people. Unknowingly, Lennie kills.
By the end of the book, Lennie is shot and dies by the hand of George.
He breaks a puppy, Curly's hand, and Curly's wife.
George says that Lennie works as strong as a bull on page 8 of "Of Mice and Men."

They sent Carlson to get the sheriff in "Of Mice and Men" by John Steinbeck after Lennie accidentally killed Curley's wife.
Lennie's job in "Of Mice and Men" is to work as a ranch hand alongside his friend George. He helps with tasks such as stacking hay, feeding animals, and doing other physical labor around the ranch. Lennie's strength and willingness to work diligently are qualities that make him valuable as a worker.
Well, honey, Lennie breaks Curley's hand in "Of Mice and Men" on page 62 of the novel. So, if you're looking to relive that dramatic moment, flip to page 62 and enjoy the chaos! Just be prepared for the fallout that comes after Lennie's little hand-breaking incident.
