This is the only bar knurling based on published in-depth research, and is the perfect blend of both grip and neurological enhancement. The knurling feels like it has a ‘bite’ to it as you grab it and feels very secure and confident in your hands. While on the more aggressive side for knurling it doesn’t feel overtly sharp and does not cut your hands just for the sake of cutting it. It does micro pentate to a specific dermal layer with its depth wich is just enough to enhance neural firing based on extensive research commissioned by OSHA. To much penetration depth that some people like because they think the sharper the better the grip, actually has inhibitory effect through protective mechanism with neurological expression. Not to mention the constant physical damage to your hands. The only time the deadlift bar should cause damage by cutting or tearing your hands is if it becomes loose and slides in your hands.
