How to Use Trauma Shears: The Ultimate Guide
How to Use Trauma Shears: The Ultimate Guide
Trauma shears aren't scissors. That distinction matters more than most people realize until they're in the field, working a patient, and every second counts. These tools are purpose-built for one thing: giving you fast, controlled access to an injury — no hesitation, no fumbling, no wasted motion.
This guide breaks down exactly how trauma shears work, how to use them correctly, and what separates a quality pair from the cheap knockoffs that fail when it matters most. Whether you're a paramedic, flight medic, firefighter, or a serious EDC carrier, this is the foundation you need.
What Makes Trauma Shears Different
Standard scissors are designed for paper, fabric, and light materials in controlled environments. Trauma shears are engineered for chaos. The differences are structural and intentional.
Blade Geometry
The angled blade on trauma shears isn't aesthetic — it's functional. That offset angle allows you to slide the lower blade flat against the patient's skin and run it under layers of clothing without lifting the shears or repositioning. You keep full contact with the surface you're cutting while staying away from the tissue underneath.
Blunt Tip Design
The blunt tip on the lower blade is a non-negotiable safety feature. When you're cutting over a patient who's moving, agitated, or in a compromised position, a sharp point creates unnecessary risk. The blunt tip lets you advance the blade with confidence without worrying about puncturing skin.
Serrated Edge
One blade typically carries a serrated edge. This matters when you hit resistance — denim, leather, webbing, or multiple compressed layers of clothing. The serration bites into material that a smooth blade would skip across. It keeps your cut moving forward without dragging or stalling.
Material and Build
Blade material determines longevity and performance under repeated use. The ONE SHEAR® BUS™ (Basic Utility Shears) are built from rolled steel — the same gold-standard construction used by professional trauma teams. The result is a blade that holds its edge, resists corrosion, and doesn't flex or bind under load. That matters on your tenth patient of the shift just as much as your first.
How to Properly Use Trauma Shears
Knowing the tool is step one. Knowing how to run it under pressure is the actual skill. Here's the technique broken down by application.
Cutting Through Clothing
Start at the hem or the least restrictive point of the garment — typically the bottom of a shirt or the ankle of a pant leg. Insert the lower (blunt) blade under the fabric with the flat side against the skin. Keep the shears angled slightly away from the body as you advance. Use smooth, deliberate strokes rather than rapid snipping. Cut along seams when possible — it reduces resistance and preserves more of the garment if preservation matters. For thick outerwear or tactical gear with multiple layers, adjust your grip pressure and let the serrated edge do the work.
Cutting Seat Belts
Seat belt webbing is dense, compressed nylon — it resists cutting more than most clothing. Position your shears perpendicular to the belt for maximum leverage. Apply firm, consistent closing pressure rather than a fast chop. The serrated blade will grip the webbing and pull it through the cut. If the belt is under tension, be prepared for sudden give once it severs — keep control of the shears and maintain awareness of the patient's position.
Cutting Bandages and Dressings
When removing bandages or cutting away field dressings, precision matters more than speed. Use the angled blade to work under existing wraps without disturbing wound packing. Short, controlled cuts give you better accuracy than long strokes when you're working close to a wound site.
Working in Low-Light Conditions
Low-light operations change the game entirely. You need to know exactly where your blade is at all times. This is where the ONE SHEAR® GHOST GLOW PRO earns its place — the photoluminescent finish charges in ambient light and stays visible in darkness, letting you locate and orient your shears by sight when a flashlight isn't an option. For night operations, vehicle extrications, or confined-space rescues, that visibility is operational value, not a gimmick.
One-Handed Technique
There are scenarios where your non-dominant hand is occupied — maintaining pressure, stabilizing a limb, holding a patient's airway. Practice opening and positioning your shears single-handed. The ergonomic handle loops on quality trauma shears are designed to allow thumb-and-finger engagement without a full grip reset. Run this in training before you need it in the field.
Carrying and Accessing Your Shears
Trauma shears you can't access in two seconds aren't tactical tools — they're pocket weight. Deployment speed depends entirely on how and where you carry them.
A dedicated shear holster mounted on your belt, chest rig, or plate carrier keeps your tool indexed and draw-ready. ONE SHEAR® carries a full line of tactical carry solutions built specifically around their shear lineup — holsters, pull tabs, and mounting options for every operational configuration.
For everyday carry where bulk matters, the ONE SHEAR® MINI delivers the same cutting capability in a compact footprint. It rides in a pocket, clipped to a bag, or secured to a keyring without the profile of full-size shears — and it still cuts through clothing, seatbelts, and bandaging material when called on.
Maintenance: Keep Your Edge
A trauma shear that binds, corrodes, or won't close cleanly is a liability. Maintenance is simple and non-negotiable.
- Clean after use: Wipe blades with an alcohol prep pad or medical-grade disinfectant after patient contact. Remove any debris from the pivot joint.
- Inspect the pivot tension: Blades should open and close with smooth, consistent resistance. Too loose and the cut wanders; too tight and you lose speed. Adjust the pivot screw as needed.
- Check for blade damage: Look for nicks, chips, or corrosion along the cutting edge before each shift. A compromised blade doesn't just cut poorly — it can snag and slow you down mid-procedure.
- Storage: Store shears in a dry environment. If your shears are autoclavable, follow manufacturer guidelines for sterilization cycles and inspect for loosening after repeated heat exposure.
If you carry IFAK setups or need to stock your kit with reliable medical tools alongside your shears, the ONE SHEAR® IFAK and medical collection is built for the same operational standard.
Choosing the Right Shear for Your Role
Not every responder needs the same tool. A flight medic working in a cramped aircraft has different requirements than a street paramedic or a law enforcement officer running a plate carrier. ONE SHEAR® builds across that spectrum — from the BUS™ for high-volume clinical and field use, to the Titanium models for weight-conscious EDC carriers, to the Tier 1 Elite for professionals who won't accept anything less than the top of the line.
Know your environment, know your mission, and carry accordingly.
Carry What Performs. Period.
