How Adjustable Tension Screws Improve Shear Performance
Adjustable tension screws are critical for ensuring smooth, precise cuts with professional shears. These screws allow you to control how tightly the blades are held together, directly impacting cutting accuracy, blade alignment, and overall tool lifespan. Proper tension ensures the blades stay in contact without creating excessive friction or strain. Here’s what you need to know:
- Too Loose Tension: Causes blades to slip, leading to uneven cuts or hair bending instead of cutting.
- Too Tight Tension: Increases friction, accelerates blade wear, and causes hand fatigue.
- Types of Systems: Flat screws (adjusted with tools), hand-adjustable systems (tool-free), and UFO screws (require a specialized tool).
- Maintenance Tips: Regular cleaning, oiling, and tension checks (e.g., drop test) are essential for optimal performance.
Adjusting tension properly not only improves cutting results but also extends the life of your shears and reduces strain during use. Investing in high-quality shears with reliable tension systems, like those made from Japanese steel, ensures durability and comfort for professional stylists.

How Adjustable Tension Screws Work
Understanding the mechanics of adjustable tension screws reveals their crucial role in achieving precise cuts. For professional stylists, maintaining optimal tension is key to ensuring smooth and accurate cutting. These screws regulate the balance between blade contact and effortless operation with each cutting stroke. Let’s take a closer look at how this mechanism works.
How the Screw Mechanism Functions
The adjustable tension screw is located at the pivot point where the shear blades meet. Professional shears are designed with a slight curvature, known as the "set", which creates a spring force. This force ensures the cutting edges stay in constant contact during use.
Turning the screw clockwise increases the pressure between the blades, while turning it counterclockwise reduces the pressure. This allows for precise adjustments to maintain proper alignment along the entire length of the blades.
Why Correct Tension Is Important
Proper tension is vital because it ensures the blades maintain continuous contact. If the tension is too loose, the spring force weakens, causing the blades to slip and reducing cutting efficiency - even if the blades are sharp.
On the other hand, over-tightening creates excessive friction as the blades scrape against each other. This not only accelerates wear but also makes the shears harder to use, leading to fatigue and potential damage like nibbling or chipping.
The goal is to strike the perfect balance: the blades should stay in contact without generating unnecessary friction. This balance ensures smooth operation and precise cutting. To maintain this, it’s a good idea to check the tension regularly - preferably at the start of each day - since cleaning, oiling, and normal wear can gradually affect blade alignment.
3 Types of Adjustable Tension Systems
Professional shears come equipped with different tension systems to ensure optimal blade contact for various cutting styles. These systems are designed to fine-tune performance, offering stylists the ability to adapt their tools to their specific techniques. Let’s take a closer look at the three main types of tension adjustment systems and what makes each unique.
Flat Screw Design
The flat screw design is a classic choice for tension adjustment in professional shears. This system uses a flat-head screw that can be adjusted with a screwdriver or even a coin, making it a simple and reliable option. Its flush design not only provides a sleek appearance but also ensures the screw stays securely in place during use. The ability to make small, precise quarter-turn adjustments allows stylists to fine-tune the tension to perfectly match their cutting style, whether they’re working on intricate detailing or general cutting.
Hand-Adjustable Screw Systems
Hand-adjustable systems are all about convenience. These systems are designed to let you change tension quickly without needing any tools. Many of these feature enhanced grip designs or click-dial mechanisms that provide tactile feedback, making adjustments effortless and precise. For instance, Saki Shears offers hand-adjustable systems that allow stylists to tweak tension between clients without disrupting their workflow. Whether you need tighter tension for detailed point cutting or a looser setting for bulk removal, these systems make adapting to different tasks quick and easy.
UFO Screw Systems
The UFO screw system stands out with its dome-shaped design, which requires a specialized tool - usually a small wrench or key - for adjustments. This unique shape is engineered to evenly distribute pressure across the pivot point, reducing wear and extending the lifespan of the shears. The UFO system is ideal for advanced stylists who need extremely precise tension control. Since adjustments can only be made with the accompanying tool, it minimizes accidental changes, making it perfect for intricate techniques like razor cutting or precision texturizing.
How to Adjust Tension Screws: Step-by-Step Guide
Getting your shears to perform just right means dialing in the tension perfectly. Whether your blades feel too loose or overly tight, these steps will help you fine-tune them for smooth, precise cutting.
Prepare and Test Current Tension
Before jumping into adjustments, it’s important to start with clean shears and check the current tension. Debris or buildup can mess with your results, so a quick clean-up is essential.
To clean, use rubbing alcohol and a small amount of scissor or machine oil (even WD-40 works). Wipe away any residue, then dry your shears thoroughly.
Next, perform the drop test. Hold your shears vertically with the tips pointing up. Open the blades to about a 90-degree angle, then let one blade drop under its own weight. Pay attention to how it moves:
- If the blade stops around the 45-degree mark, your tension is good.
- If it slams shut or closes completely, the tension is too loose.
- If it barely moves or stays open, the tension is too tight.
For extra accuracy, try the 1/4-inch gap test. Hold the shears at a 30-degree angle with the tips pointing slightly upward. Open the blades to about 60 degrees, then release. The blades should close on their own and stop with a 1/4-inch gap between the tips if the tension is correct. Once you’ve assessed the current tension, you’re ready to make adjustments.
Make the Adjustment
Now that you know what needs fixing, it’s time to adjust the tension screw. Use the right tool for your shears - most standard screws require a Phillips head screwdriver or a tension adjuster key, while hand-adjustable screws can be turned manually.
Work in small steps. Turn the screw clockwise to tighten or counterclockwise to loosen, but keep the adjustments minimal - think about 1/16th of an inch or just one or two clicks. You might hear a slight "click" as you turn, which is completely normal. Avoid making large adjustments, as they can throw off the balance and make it harder to fix.
For flat screws, use gentle quarter-turns with your screwdriver. Hand-adjustable systems often "click" with each turn, making it easier to track your progress. If your shears use a UFO screw system, you’ll need the specialized tool, but the same principle applies: small, precise movements. After each adjustment, test and fine-tune until the tension feels just right.
Test and Fine-Tune Your Settings
Once you’ve made an adjustment, it’s time to check your work. Start with the drop test or 1/4-inch gap test to see how the adjustment has affected the blades. Ideally, the blade should now stop at the 45-degree mark during the drop test.
But don’t stop there - real-world performance is what counts. Test your shears on hair or tissue to see how they perform. If the shears bend or slip, tighten the screw slightly and test again. If they feel stiff or cause hand fatigue, loosen the screw a bit and retest.
Keep making small tweaks until your shears glide through cuts effortlessly. This trial-and-error process helps you find that perfect balance where the blades cut smoothly without requiring extra force or straining your hand.
Keep in mind that different cutting styles may call for slightly different tensions. For example, stylists often prefer tighter tension for precision cuts and looser tension for bulk trimming. Once you’ve found your ideal setting, take note of the screw position so you can easily return to it later.
Spending just a few minutes on this process can make a huge difference in how your shears perform. For the best results, check and adjust the tension regularly - once a week or even daily if you’re a busy professional. This simple habit not only improves cutting performance but also helps extend the life of your shears.

Common Tension Adjustment Mistakes to Avoid
Even seasoned pros can slip up when tweaking tension screws, leading to damaged tools, uneven cutting, and unnecessary costs. Getting the tension just right is key to keeping your shears in top shape. Let’s look at some common mistakes and how to avoid them.
Over-Tightening the Screw
Cranking the tension screw too tight can wreak havoc on your shears. It increases friction, making the shears stiff and causing excessive wear on the pivot points. Over time, this can lead to micro-chipping along the blade edges, which dulls your tools far faster than normal use.
How can you tell if you’ve over-tightened? Your shears might feel rigid, make grinding noises, or require extra effort to open and close. The cutting motion may become jerky instead of smooth, and the blades might bind or catch during use. These are all red flags that the tension is too tight.
Under-Tightening the Screw
On the flip side, leaving the tension too loose can misalign the blades. This misalignment causes the blades to separate, leading to clicking sounds and uneven cuts. Fine hair, in particular, will slip between the blades instead of being cleanly cut, which is a nightmare when precision is critical.
Loose tension also affects your control. The blades might twist or shift mid-cut, making it nearly impossible to achieve clean lines or consistent lengths. This is especially frustrating for detail work or geometric styles.
A quick way to check for under-tightening is to try pulling the blades apart gently. If they separate with minimal effort, the tension is too loose. Properly adjusted shears should offer slight resistance when you manually test the blade separation.
Skipping Regular Maintenance
Neglecting routine maintenance is another common pitfall that can compromise your shears. Daily use naturally causes wear on pivot points and screw threads, and hair products, moisture, and debris can build up around the tension mechanism. Over time, this buildup affects how well the screw holds its position.
If you skip maintenance, you might notice a gradual decline in performance. By the time the problem becomes obvious, you could be looking at costly repairs or even the need for replacement parts - issues that could have been avoided with simple upkeep.
A solid maintenance routine includes weekly tension checks and monthly deep cleaning of the pivot area. This involves clearing away any buildup around the screw, ensuring the tension feels consistent, and making minor adjustments as needed. Even professional-grade shears, like those from Saki Shears, benefit from this regular care.
Signs of skipped maintenance include inconsistent cutting, changes in how the shears feel during use, or finding that your usual tension setting no longer works as it should. Regular upkeep not only prevents these problems but also helps you catch small issues early, saving you from bigger headaches down the line.
Conclusion: Proper Tension for Better Shear Performance
Maintaining the right shear tension is a daily commitment that directly impacts every cut you make. The adjustable tension screw plays a key role in ensuring precision, extending the life of your tools, and providing the comfort you need as a professional stylist or barber.
