Step 6: Test for Sharpness
Now that your shears are sharpened, it’s essential to test them:
-
Perform a cut test: Try cutting through some branches or stems to see how easily the shears cut. They should slice through with minimal effort.
-
Adjust if necessary: If they are still not up to par, you may want to repeat the sharpening process or refine the angle further.
Maintaining Your Garden Shears
Keeping your shears in good condition is easier and more effective than sharpening them from scratch repeatedly. Here are some tips for maintenance:
Regular Cleaning
Always clean your shears after each use. This prevents sap and dirt build-up and prolongs the lifespan of the blades.
Frequent Inspection
Periodically check the sharpness of your shears. Catching dullness early means less grinding later.
Proper Storage
Store your shears in a dry place, away from moisture, to prevent rust. Hanging them or placing them in a protective sheath can help keep the blades intact.
