@momentsgang: These hammers have a bendy or flexible handle to absorb shock and reduce vibration during use. This design helps minimize strain on the user’s hand and arm, especially during prolonged work. The flexible handle, often made from materials like fiberglass or specialized rubber, cushions the impact when striking, leading to more comfortable and controlled hammering. This feature is particularly useful in construction and carpentry, where repeated use can lead to fatigue or joint pain.
