There are exceptions to the above descriptions of both garden tools. Some garden scissors have features usually associated with garden shears. You may find examples with curved blades, or you may find garden scissors that have one handle with a finger space, and a thumb side with a squeeze handle. Others have double squeeze handles, like those seen on shears.
Of all the kinds of garden shears, those called floral shears are most often designed like garden scissors. They are more likely to have bows, and may have blades that are remarkably like craft scissors, though often they are serrated. Because the features associated with each name vary, it is a good idea to be careful when choosing scissors or shears.
