Winter is a Great Time to Sharpen Garden Tools

When you're in a hurry to get your pruning work done, you may not want to take the extra few minutes needed to stop and sharpen your tools. But it's well worth the effort for two reasons:

(1) Your work will go faster and easier with sharpened tools.
(2) The clean cuts you get with sharpened tools are healthier for your plants and trees.
So why not take the time this winter to get your pruners and shears ready for spring.

Whatever type of pruning tool you are using, clean the blade with a stiff brush and soapy water to remove any rust, clumped dirt or other debris. Dip the pruners in a solvent, such as kerosene, to clean off any sap. If you've used your tools on evergreens, be sure to clean off the pitch residue using either oil or kerosene. After drying them, wipe the blades with a light coat of motor oil.

Examine the blade edge to determine the correct sharpening angle (usually about 10 to 15 degrees). Remember, for an anvil-type pruner, you'll sharpen only one blade but you must sharpen that blade on both sides.

The choice of sharpening tools is largely a matter of preference:

Whetstones, the most common choice, offer many gradations and sizes, though you may find that a longer one is easier to work with.
A diamond-coated flat file requires only water for lubrication, remains flat for fast sharpening and is durable enough to last a lifetime.
A sharpening steel is useful for finishing or for a quick fix.
Grinding stones require extra caution because they transfer friction heat that can affect the metal temper, making it more brittle. This is not recommended.

Once you've finished sharpening your tools, apply a light coat of oil to the blades. Remember dirt that sticks to your tools acts as a sponge, collecting moisture and causing rust. So be sure to keep dirt off your tools when they're not in use.

When sharpening other types of tools, you may need to make some modification of these steps. For example, when sharpening a machete or hatchet, sharpen both sides of the blade. And one last tip: before sharpening shears, you might find it easier to take them apart.
