Secateur Problems Explained: Blunt Blades, Sticking & Rust

Even the best secateurs can become frustrating to use if common problems aren’t addressed. Blunt blades that crush stems, secateurs that stick or won’t spring open properly, and rust forming on metal parts are all issues UK gardeners face — especially with frequent use and damp conditions.

The good news is that most secateur problems are easy to fix with a little understanding and basic maintenance. This guide explains the most common secateur problems, why they happen, how to fix them, and how to prevent them from coming back — so your secateurs stay sharp, smooth and reliable throughout the growing season.

Why Secateurs Develop Problems

Secateurs are simple tools, but they work under constant stress. Every cut puts pressure on the blades, spring and pivot point. Over time, sap, moisture, dirt and repeated friction take their toll — especially in the UK’s often wet climate.

Most problems fall into three main categories:

• Blades that go blunt
• Mechanisms that stick or feel stiff
• Rust forming on metal parts

Understanding what causes each issue makes them much easier to deal with.

Problem 1: Blunt Secateur Blades

How to Spot Blunt Blades

Blunt blades are the most common secateur issue. Signs include:

• Stems being crushed rather than cleanly cut
• Needing much more hand pressure to make a cut
• Ragged or torn plant tissue after pruning
• Slipping off stems instead of slicing through

Blunt blades don’t just make pruning harder — they also damage plants, increasing the risk of disease and slowing healing.

---

Why Secateur Blades Go Blunt

Blades dull for several reasons:

• Regular use — normal wear from cutting plant fibres
• Cutting hard or woody material beyond the tool’s capacity
• Contact with soil, grit or stones while pruning near ground level
• Poor storage allowing blades to knock against other tools
• Rust pitting, which damages the cutting edge

Even premium secateurs will dull if they’re used frequently without sharpening.

---

How to Fix Blunt Blades

1. Sharpen the Blade

Sharpening restores cutting performance quickly.

• Use a secateur sharpening stone or file
• Follow the existing bevel angle of the blade
• Sharpen only the cutting blade (on bypass secateurs)
• Make smooth strokes away from your body
• Finish by lightly removing burrs from the back edge

You don’t need to remove much metal — frequent light sharpening is better than occasional heavy sharpening.

2. Clean Before Sharpening

Always clean sap and debris off the blade first. Sap can clog the stone and prevent effective sharpening.

3. Check Blade Alignment

If blades don’t meet properly, sharpening alone won’t help. Tighten pivot screws if loose, or realign blades if possible.

---

How to Prevent Blunt Blades

• Sharpen little and often
• Avoid cutting stems thicker than the tool’s rated capacity
• Use loppers or saws for heavy wood
• Keep blades clean and dry
• Store secateurs closed or in a sheath

---

Problem 2: Secateurs That Stick or Feel Stiff

How to Spot Sticking Secateurs

Sticking or stiff secateurs may:

• Fail to spring open fully
• Feel jerky or uneven when opening and closing
• Require manual opening with your fingers
• Feel stiff even when blades are sharp

This makes pruning slow, tiring and uncomfortable.

---

Why Secateurs Start Sticking

Common causes include:

• Sap build-up around the pivot and blades
• Dirt and grit working into the mechanism
• Dry or corroded pivot points
• Weak, bent or worn springs
• Over-tightened pivot screws

Sap from plants like roses, figs and many shrubs is a frequent culprit.

---

How to Fix Sticking Secateurs

1. Deep Clean the Tool

Cleaning is the first and most effective step.

• Open the secateurs fully
• Wipe blades and pivot with a cloth
• Use warm water and mild detergent if sap is heavy
• Dry thoroughly before reassembly

For stubborn sap, rubbing alcohol or vinegar on a cloth can help.

2. Oil the Pivot and Spring

Apply a drop of light machine oil or general-purpose oil to:

• The pivot bolt
• The spring ends
• Any moving joints

Open and close the secateurs several times to distribute the oil.

3. Check Spring Condition

If the spring feels weak or uneven:

• Inspect for bending or cracking
• Replace the spring if possible (many models allow this)

A worn spring is a common cause of poor opening action.

4. Adjust the Pivot Screw

If the pivot is too tight:

• Loosen it slightly until movement feels smooth
• Ensure blades still meet cleanly without wobble

---

How to Prevent Sticking

• Wipe sap off blades after every pruning session
• Oil pivot points regularly, especially in wet weather
• Avoid leaving secateurs dirty overnight
• Store tools in a dry place

---

Problem 3: Rust on Secateurs

How to Spot Rust Early

Rust often starts subtly. Look for:

• Orange or brown spots on blades
• Rough patches on the cutting edge
• Stiff movement after storage
• Pitting or flaking metal

Left untreated, rust spreads quickly and permanently damages blades.

---

Why Secateurs Rust

Rust forms when metal is exposed to moisture and oxygen. Common causes include:

• Storing tools wet after use
• Leaving secateurs outside or in damp sheds
• Sap and plant juices holding moisture against metal
• Not oiling blades and pivots
• Condensation in unheated storage

UK weather makes rust a constant threat if tools aren’t cared for.

---

How to Remove Rust from Secateurs

1. Light Surface Rust

For early rust:

• Use fine steel wool or a wire brush
• Gently rub until rust is removed
• Wipe clean and dry thoroughly

2. Heavier Rust

For more stubborn rust:

• Apply white vinegar or a rust remover
• Leave for a short period
• Scrub with a brush
• Rinse, dry and oil immediately

3. Restore the Cutting Edge

After rust removal, lightly sharpen the blade to restore a smooth cutting surface.

---

How to Prevent Rust

• Always dry secateurs after cleaning
• Lightly oil blades and pivot before storage
• Store in a dry, ventilated place
• Avoid leaving tools on soil or grass
• Use a blade cover or cloth wrap in winter

Other Common Secateur Issues (And Quick Fixes)

Loose Blades or Wobble

Cause: Pivot screw loosening over time
Fix: Tighten carefully until blades meet cleanly

---

Blade Misalignment

Cause: Dropping tools or heavy cutting
Fix: Realign if possible or replace blade on serviceable models

---

Handles Slipping or Feeling Uncomfortable

Cause: Worn grip coating or wet conditions
Fix: Clean grips; consider grip tape if worn

---

Spring Keeps Falling Out

Cause: Incorrect spring fit or worn housing
Fix: Replace with correct spring or check seating position

---

How Often Should You Maintain Secateurs?

A simple rule of thumb:

• After every use: Wipe blades clean
• Weekly (during heavy use): Oil pivot and spring
• Monthly: Light sharpening
• Seasonally: Deep clean, rust check, full sharpening

Frequent light maintenance prevents nearly all major problems.

---

When Problems Mean It’s Time to Replace Secateurs

Even with good care, secateurs don’t last forever. Replacement may be needed if:

• Blades are deeply pitted with rust
• Blade alignment can’t be corrected
• Handles are cracked or bent
• Replacement parts are no longer available
• Cutting performance doesn’t improve after sharpening

In these cases, investing in a new, serviceable pair is often more cost-effective.

---

Preventative Care Checklist

To avoid blunt blades, sticking and rust:

• Clean after every pruning session
• Sharpen regularly
• Oil moving parts
• Store dry
• Use the right tool for the job
• Avoid cutting beyond capacity

These habits take minutes but save years of tool life.

Final Thoughts

Blunt blades, sticking action and rust are the three most common secateur problems — but they’re also the easiest to fix and prevent. Most issues come down to dirt, moisture and lack of routine maintenance rather than poor-quality tools.

With regular cleaning, light sharpening and proper storage, even modestly priced secateurs can deliver years of reliable service. Keeping your secateurs in good condition means cleaner cuts, healthier plants and far more enjoyable pruning — season after season.
