Unlike nail driving, a chisel must be held for every strike. The holder makes it possible to hold without being in the hammer's path.
IM-001 covers finger saver devices for nail and pin driving — tasks where the workpiece is small, the first few strikes are the hazard window, and the device is withdrawn once the fastener is self-supporting. Chisel and cold chisel work is a different exposure profile entirely. The chisel is never self-supporting. It must be held throughout the entire driving sequence — every strike, from first to last. The hand is in the strike zone for the full duration of the task, not just the first seconds.
Cold chisels are also driven with heavier hammers, higher forces, and greater recoil than nail driving. The energy transferred at a missed or glancing strike is significantly higher. A finger saver device is not rated for this. A dedicated chisel holder — with grip geometry and collar designed for the lateral forces of chisel driving — is the appropriate control.

| Control Category | Impact Mitigation Controls — Chapter IM |
| Primary Function | Holding the chisel or cold chisel during driving so the hand grips the holder, not the chisel body — removing the hand from the strike and recoil zone |
| Exposure Reduction Mechanism | Physical displacement — holder geometry positions the hand behind a collar or guard that prevents forward migration toward the struck face |
| Separation Distance | Typically 100–300 mm between the gripping hand and the chisel tip, depending on holder length and chisel size |
| Control Level | Engineering — separation is enforced by holder geometry, not by the worker's grip position in the moment |

The historical method was to grip the chisel shaft directly — thumb and fingers wrapped around the body, hand positioned as close to the struck face as the worker felt comfortable. Gloves were issued as primary protection. The accepted response to a struck hand was to improve technique, use a heavier glove, or accept that occasional strikes were an occupational hazard. Chisel holders were available but treated as optional aids rather than standard controls. The PSC 18" Chisel & Punch Grip Holder (legacy MSA product, now PSC Originals range) established the dedicated holder as a primary control, not an accessory.
The following are examples of this control method in current industrial use. The control method is the subject — the product is the answer.
"A chisel requires a hand for every strike. The holder ensures that hand is behind the collar — not in the path of the hammer — for every one of them."
