Find an old pair of Wiss that haven't been sharpened improperly. The flat side of the blades should never touch a stone. I've had an old pair in my shop for over 20 years and a little maintenance has them cutting like new.
x2, the inside does not need to be touched, other than to knock off the burr with a nail file after grinding a new edge on them. Other sharpeners will gouge the backs or wipe out the tips by being too heavy handed at the beginning and end of the stroke when sharpening. All of our scissor machines have tool holders and we can set the angle we want to sharpen the blades at and get consistent results.
Rust is the other killer of clipper blades and shears. When it gets to the point of creating pits in the steel, it effects how they cut.
My garage shears might be fiskars and were about 20 bucks, a number of years ago. They have a corrugated edge on at least one side. I don't know if it helps much for utility use. For grooming and salon use, our customers rarely request we corrugate their shears, but the wheels we use for a bevel edge help keep the hair from sliding on the edge of the blades. At my computer desk, I have kobal shears. They are nice for paper and are comfortable and sturdy but nothing fancy.
Apparently there are rumors that cutting paper towels or paper with good shears will damage them. Paper towels are one of the tools I keep in my sharpening bag. I wouldn't recommend using convex edge shears on paper all of the time, they were built to cut hair, but cutting the right kind of paper towel can tell you a lot about the condition of your shears.
Upholstery shops will use older shears that are well built and they are often in the style of the Wiss. If you take care of them and have a good sharpener service them, nice tools are great. If they will get beat up or you don't want to deal with having shears sharpened, just buy another pair for 5-30 dollars.
In the grooming industry, good shears cost between 80 and 250 dollars per pair and we have worked on some that sold for as high as $1400 per pair. Many animal groomers consider $40 shears to be great, but they are hit and miss with the quality and how they sharpen vs. something closer to 100 dollars and up. Shears for home and garage use are generally pretty dang cheap in comparison to what other pros use.
Now if you to ask me about side cutters or linesmans pliers, I would say Klein Journeyman only. With scissors, for the garage, I don't think you have to spend as much money.
