How to Use Trauma Shears: A Quick Guide for Beginners

Trauma shears aren't just another piece of kit — they're the tool you reach for when seconds determine outcomes. Whether you're cutting through a denim jacket to expose a GSW, slicing a seatbelt off a trapped driver, or accessing a limb for tourniquet placement, your shears have to perform without hesitation. No fumbling. No second attempts. Just a clean, controlled cut.

If you're new to emergency medicine, EMS, or tactical response, this guide breaks down everything you need to know about using trauma shears correctly — from understanding how they're built to executing proper cutting technique under pressure.

Understanding Trauma Shear Anatomy

Before you put shears to use in the field, you need to understand what you're working with. Every component of a quality pair of trauma shears has a purpose. Here's what matters:

Blades

Rolled steel or stainless steel blades are the standard. They need to be thick enough to handle multiple layers of material without flexing, yet sharp enough to initiate a cut without excessive force. The ONE SHEAR® BUS™ (Basic Utility Shears) uses rolled steel construction — the same approach that defines the gold standard in trauma shears. That build matters when you're fighting through leather boots, tactical webbing, or winter gear.

Serrated Edge

One blade typically runs serrated. This isn't aesthetic — serrations bite into material and prevent slippage, especially on synthetic fabrics and seatbelts that tend to slide under a smooth blade. Without that grip, you're dragging and tearing instead of cutting.

Blunt Safety Tip

The blunt lower tip is non-negotiable in a clinical or field setting. It allows you to slide the shears beneath clothing and along the skin without puncturing tissue. In high-stress, low-visibility environments, that tip is the difference between accessing an injury and creating one.

Handles and Grip

Ergonomics matter more than most people acknowledge. When your hands are wet with blood, sweat, or rain, a handle without proper grip geometry becomes a liability. Quality trauma shears feature handles designed for bare hands and gloved hands alike — a detail ONE SHEAR® takes seriously across every model in the lineup.

Pivot Point

The pivot is where shears fail under repeated use. A loose or poorly constructed pivot causes blade misalignment, which degrades cutting performance fast. A solid, consistent pivot ensures both blades track true through every cut — essential when you can't afford a shear that chatters or binds mid-stroke.

Step-by-Step: How to Use Trauma Shears Correctly

Technique is everything. Here's how to use trauma shears effectively, whether you're in a training environment or responding to an actual emergency.

Step 1: Inspect Before You Deploy

Check your shears before every shift. Blades should move smoothly with no play at the pivot. Look for nicks, corrosion, or handle cracks. If they're compromised, swap them out — your shears are not the place to cut corners. Keep a backup pair in your IFAK or medical kit and rotate them regularly.

Step 2: Establish a Safe Entry Point

Slide the lower blade (blunt tip) between the clothing and the patient's skin. Start at a natural opening — waistband, collar, sleeve — and angle away from the body as you work upward. Never force the blade or assume positioning based on where clothing sits. Feel for resistance and adjust. Speed is important, but a puncture wound from your own shears is unacceptable.

Step 3: Apply Controlled, Deliberate Cutting Strokes

Use full, deliberate strokes rather than short choppy ones. Long strokes let the full blade length work and reduce fatigue. Keep consistent tension on the material with your free hand to maintain a taut cutting surface. Loose, bunched fabric is harder to cut cleanly and increases the chance of the blade skipping off course.

Step 4: Cut Along Seams When Possible

Seams are weaker than the main fabric body. Cutting along them requires less force and reduces the risk of the shears binding. On tactical clothing, body armor carriers, or heavy workwear, following the seam line also gives you a more controlled exposure of the injury site.

Step 5: Remove and Expose Efficiently

Once you've made your primary cut, peel the material back and expose the injury site fully before beginning assessment. Partial exposure leads to missed injuries. Cut both sides if needed — don't rush the exposure phase to get to treatment faster. You can't treat what you can't see.

Step 6: Secure Your Shears After Use

Don't set them down on the ground or toss them in a bag loose. Use a dedicated holster or retention clip to keep them accessible and protected. ONE SHEAR® offers purpose-built holsters and EDC accessories designed for exactly this — fast deployment and secure retention when you're moving fast.

Low-Light and High-Stress Scenarios

Not every emergency happens in a well-lit ambulance bay. Flight medics, tactical medics, and overnight responders know that operating in the dark adds a significant layer of complexity. That's where tools like the ONE SHEAR® GHOST GLOW PRO earn their place — glow-in-the-dark trauma shears built specifically for low-light operations. When you can't see your kit, you need your kit to find you.

For professionals who need compact, always-on-body carry, the ONE SHEAR® MINI fits the bill — small enough for a scrub pocket or chest rig, capable enough for real clinical work. Explore the full compact carry lineup at ONE SHEAR® MINI Shears.

Common Mistakes to Avoid

• Using dull shears: Dull blades require more force, reduce control, and increase patient risk. Replace or sharpen on a regular schedule.
• Short, choppy strokes: These bind fabric and slow you down. Use full strokes and let the blade do the work.
• Skipping the blunt tip entry: Forcing blades under clothing without using the blunt tip as a guide is how patients get secondary injuries from responders.
• Neglecting maintenance: Trauma shears exposed to blood, fluids, and debris need regular cleaning. Neglect shortens blade life and creates biohazard risk.
• Carrying without retention: Loose shears in a pocket are slow to deploy and easy to lose. Use a proper holster.

Choosing the Right Shears for Your Role

Not every pair of trauma shears is built for every job. A flight medic working in a cramped helicopter cabin has different needs than an ER nurse or a law enforcement officer carrying concealed. ONE SHEAR® builds across that entire spectrum — from the full-size BUS™ and Tier 1 Elite (T1E) for heavy professional use, to the MINI for compact everyday carry, to the GFR Responder series for front-line emergency response. Titanium models address the weight-conscious EDC crowd without sacrificing edge retention or durability.

The right shears aren't the most expensive ones — they're the ones that fit your kit, your environment, and your hands. Train with what you carry.
