What Is the Lever for on Hair Clippers? Complete Guide

The lever on hair clippers is a taper lever (also called an adjustment lever) that moves the top blade forward or backward to adjust cutting length by approximately 0.5mm–1mm without changing guards. This feature allows barbers and home users to blend, fade, and fine-tune haircuts with precision, creating seamless transitions between different guard lengths for professional results.

How the Taper Lever Works

The Mechanism

Hair clippers have two blades:

• Bottom blade (stationary): Remains fixed in place
• Top blade (moving): Oscillates back and forth to cut hair

The taper lever adjusts the position of the top blade relative to the bottom blade:

• Lever closed (down position): Top blade moves forward—cuts longer (adds ~0.5mm–1mm)
• Lever open (up position): Top blade moves backward—cuts shorter (removes ~0.5mm–1mm)

This adjustment changes cutting length without swapping guards, making it essential for fades, blends, and detailed work.

Lever Positions Explained

Lever Position	Blade Position	Cutting Length	Best Use
Closed (Down)	Top blade forward	Longer (adds 0.5–1mm)	Bulk cutting, initial passes
Half-Open (Middle)	Top blade partially back	Medium	Blending, transitioning
Open (Up)	Top blade fully back	Shortest (removes 0.5–1mm)	Close cuts, fades, tight blends

Key Point: Some people confuse the terminology. "Open" means the lever is in the up position (blades are farther apart, cutting closer). "Closed" means lever down (blades closer together, cutting longer).

What the Taper Lever Is Used For

Fading and Blending

The taper lever creates smooth transitions between different guard lengths:

1. Start with a longer guard (#3 or #4) at the top
2. Switch to a shorter guard (#2) for the sides
3. Use the taper lever in various positions to blend the line where the two lengths meet

Without a taper lever, you'd see harsh lines between guard lengths.

Fine-Tuning Length

The lever lets you adjust cutting length by small increments (0.5mm–1mm) without changing guards. This is crucial when:

• A guard cuts slightly too short
• You need a length between two guards
• You want to customize a fade

Detail Work and Edging

Barbers use the lever in the open position for:

• Tight neckline clean-ups
• Sharp sideburn edges
• Close buzz cuts

Extending Guard Range

A #1 guard typically cuts at 3mm. By adjusting the lever:

• Lever closed: ~3.5–4mm
• Lever half-open: ~3mm
• Lever fully open: ~2.5mm

This effectively gives you three lengths from one guard.

How to Use the Taper Lever

For Fades

1. Start with longer guard: Use #3 or #4 at the top with lever closed
2. Switch to shorter guard: Use #2 for the sides
3. Blend the transition: At the line where lengths meet, use lever in half-open position and flick upward to fade the line
4. Repeat with shorter guards: Continue process down to #1 or zero-gap for skin fades

For Even Cuts

• Lever closed (down): For consistent length across the entire head
• Keep lever in same position: Don't adjust mid-cut unless intentionally fading

For Adjusting Length Without Changing Guards

• Cutting too short? Move lever to closed position (longer)
• Need it closer? Move lever to open position (shorter)

Taper Lever vs. Adjustable Blade Clippers

Some clippers have adjustable blades instead of a taper lever. Here's the difference:

Feature	Taper Lever Clippers	Adjustable Blade Clippers
Mechanism	Lever moves top blade	Dial or wheel adjusts blade gap
Adjustment Range	0.5–1mm	0.5–2.5mm (wider range)
Speed	Instant (flip lever mid-cut)	Slower (requires stopping to dial)
Precision	Less precise (3 positions)	More precise (click settings)
Best For	Fades, blending	Versatile length control

Bottom Line: Taper levers are faster for fades; adjustable blades offer more control for varied lengths.

Common Mistakes When Using the Taper Lever

Not Keeping Lever Consistent

Accidentally moving the lever during a cut creates uneven length. Choose a position and stick with it unless intentionally blending.

Using Closed Lever for Fades

Fades require the lever in the open position for the closest cut. Starting with the lever closed defeats the purpose.

Forgetting to Adjust After Blending

If you use the lever to blend, remember to return it to your default position (usually closed) before continuing with the main cut.

Forcing the Lever

If the lever feels stuck, turn off the clipper, clean debris from the blades, and apply clipper oil. Forcing it can break the mechanism.

Maintaining Your Taper Lever

Keep Blades Clean

Hair and oil buildup can jam the lever mechanism:

1. Brush away hair after each use
2. Apply clipper oil weekly
3. Deep clean monthly with blade wash

Oil Regularly

Apply 2–3 drops of clipper oil along the blade teeth and cycle the taper lever through all positions to distribute oil evenly.

Check for Blade Alignment

If cutting becomes uneven:

1. Remove the blade assembly
2. Realign the top and bottom blades
3. Tighten screws securely

Do All Clippers Have Taper Levers?

No. Taper levers are common on:

• Professional barber clippers
• Home clippers designed for fades
• Versatile all-purpose models

Budget or basic clippers often lack taper levers. If fading and blending are important, choose a model with this feature.

Frequently Asked Questions

What is the lever for on hair clippers?

The lever (taper lever) adjusts the top blade position to change cutting length by 0.5–1mm without changing guards. It's used for fading, blending, and fine-tuning haircuts. Lever closed (down) cuts longer; lever open (up) cuts shorter.

Should the clipper lever be up or down?

Down (closed): For longer, consistent cuts and bulk removal. Up (open): For shorter, closer cuts, fades, and blending. Most people keep the lever closed for general cutting and open it for detail work.

What does the taper lever do?

The taper lever moves the top blade forward (closed) or backward (open) to adjust cutting length. This allows seamless blending between guard lengths, creating smooth fades without harsh lines.

How much length does the taper lever add or remove?

Approximately 0.5mm to 1mm depending on the clipper model. This small adjustment is enough to blend guard transitions smoothly.

Do I need a taper lever for home haircuts?

Not for simple buzz cuts, but yes for fades, blends, or any haircut with multiple lengths. The lever makes transitions look professional instead of choppy.

Can I fade hair without a taper lever?

Yes, but it's harder. You'd need more guard sizes and careful technique to avoid harsh lines. The taper lever simplifies the process significantly.

Conclusion

The lever on hair clippers is a taper lever that adjusts cutting length by 0.5–1mm, allowing you to fade, blend, and fine-tune haircuts without changing guards. Understanding how to use it—closed for longer cuts, open for shorter—transforms your ability to create professional-looking fades and seamless transitions.
