Florist’s Guide to Sharpening Shears
Florist shears (also called floral scissors, pruning shears, or snips) are essential tools for cutting flowers, trimming stems, and arranging bouquets. Over time, blades can become dull, making cuts ragged and damaging delicate stems. Keeping your shears sharp ensures clean, precise cuts that help flowers stay fresh longer.
This SG Florist guide will walk you through the best techniques for sharpening and maintaining your florist shears.
1. Signs Your Shears Need Sharpening
Your shears may be dull if:
✔ They crush stems instead of slicing cleanly.
✔ Cutting requires extra force.
✔ The blades stick together or pull on stems.
✔ They tear leaves and petals rather than making smooth cuts.
2. Tools You’ll Need for Sharpening
Sharpening stone (whetstone) – Ideal for a fine, smooth edge.
Diamond file or carbide sharpener – Quick and effective for minor touch-ups.
Sandpaper (600-1000 grit) – Useful for polishing and smoothing edges.
Steel wool or wire brush – Helps remove rust and debris.
Lubricating oil (WD-40, mineral oil, or machine oil) – Prevents rust and keeps the shears moving smoothly.
3. How to Sharpen Your Florist Shears
A. Cleaning the Blades
Wipe down the shears with a damp cloth to remove dirt and sap.
Use steel wool or a wire brush to scrub away rust or residue.
Dry completely before sharpening.
B. Sharpening with a Whetstone
Soak the whetstone in water for 10-15 minutes (if using a water stone).
Hold the shears at a 20-30° angle against the stone.
Slide the blade across the stone in one direction (not back and forth), using light, even pressure.
Repeat 5-10 times or until sharp.
Flip and sharpen the other blade, if your shears have two beveled edges.
C. Using a Diamond File or Carbide Sharpener
Place the file or sharpener along the beveled edge of the blade.
Move it in a single direction (away from your body) 5-10 times.
Test the sharpness on a flower stem and repeat if needed.
D. Finishing & Polishing
Use fine-grit sandpaper (600-1000 grit) to smooth the edge.
Apply lubricating oil to prevent rust and improve movement.
4. Maintaining Sharp Shears
✔ Wipe blades clean after each use to remove sap and debris.
✔ Oil the pivot joint occasionally to keep movement smooth.
✔ Store in a dry place to prevent rust.
✔ Sharpen every 2-3 months (or as needed, depending on use).
Sharp shears make flower arranging easier, more precise, and help extend the life of your blooms. By regularly cleaning, sharpening, and maintaining your tools, you’ll keep them in excellent condition for years to come.
