You can use a file. On shears, follow the original grind. Be sure to file off any burr that filing creates on the flat side. File down of any rounding and file the flat side keeping it flat, don't drive back at an angle on the flat side or it won't shear. Only file on the forward stroke, not on the back stroke.
If you have a grinder, that is much easier, just be careful and don't overheat the blade. Grind a little and let it cool a bit. If you keep it from bluing you won't loose the temper of the steel. Pay attention to the angle of the grind, the cleaner and smoother the finish, the better it will cut.
The steel on blades can be pretty tough. Filing may be kind of difficult.

I worked all day today trying to trim the boxwoods,yarrow, and grasses. The tools have gotten dull, and needless to say, it made working a harder chore. Does anyone know how to DIY sharpen the hand tools. I have the one that looks like a giant pair of scissors (not sure what to call them) and the hand trimmers. Do I just have to buy new?
