Tips in Sharpening Lopping Shears and Hedge Shears

2016-06-03

As a matter of fact, both hedge shears and lopping shears work like scissors, using blades beveled on one side to slice through whatever they cut. However, unlike scissors, lopping shears usually have a curved blade and a curved hook to meet it, rather than two straight blades. The curve prevents a branch from slipping away as you slice down, but it also presents a unique challenge when sharpening.  Functional Solar Light with two straight blades look more like oversize scissors, but they may have a serrated edge on the blades, unlike scissors. This article, we will teach you how to sharpen lopping shears and hedge shears.

Firstly, the hedge shears.

Clamp one blade horizontally in a vise with the sharp side up. Examine the edge to see whether it's serrated or straight. Then, rub a small round pencil-shaped file or sharpening stone along the edge if the blade is serrated. Hold the file or stone so it contacts the blade at the angle of the bevel. Let it follow the serrations, rising and falling as you stroke it along the edge. If the blade is straight, use a broader flat sharpening stone or file. Hold it at the angle of the bevel and stroke it along the full length of the blade.

Next, unclamp the blade from the vise and clamp the other one. Sharpen it the same way. After sharpened both blades, examine them to see if a small burr or wire edge sticks up on the flat side. If it does, rub a flat stone or file once or twice lightly along the flat side to remove the burr, keeping the file or stone flat against the surface. But don't add any bevel to the flat side.

Then, the lopping shears.

Open the shears and lay them on a work table with the curved blade hanging over the edge and its beveled side up. You only need to sharpen the bevel-edged blade, but not the C-shaped hook that it slices against.

Hold a small triangular file or a narrow flat stone against the beveled edge at an angle so its flat side touches the bevel. Stroke along the edge several times, following the curve of the blade.

And finally, rub the flat side of the blade with the stone or file only if you notice a small burr or wire edge extending over it, after you sharpen the beveled side. Keep the file or stone flat against the flat side and be careful not to add any bevel while removing the burr.
