Abstract: A hand-held spring-driven impact device (e.g., spring tool) configured with removable and replaceable tips. The spring tool may include a helical spring that is coupled to a first anvil at one end and a second anvil at the other end. The spring tool may include a locking mechanism on the first anvil and/or the second anvil. The locking mechanism may be configured to securely fasten a tip to the spring tool. The tip may include a single-sided tip or a double-sided tip. The spring tool may include an ergonomically curved gripping surface and/or a friction component to assist in holding the spring tool. In some examples, the spring tool may include a ball bearing situated between the first anvil and the second anvil to transfer impact force when applied at an angle. Additionally, the spring tool may include a cover to protect the spring during use.
