Making craft scissors for the other 15%

August 13th is International Left-Handers Day, but since most of us are right-handed, you'd probably never even thought about left-handed scissors until you tried to cut the finger nails on your right hand using your left. Now you get it; It’s hard to do that, right?

Welcome to the lefties’ world where everything is built for righties. It can be an eyeopener and a good reminder that 10-15% of the general population is poorly served when it comes to scissors.

Alpen Perfect Lefty left-handed scissors

For most activities, it doesn’t matter which hand you use. Certainly not for swinging a baseball bat. About a third of professional baseball hitters bat left and, no surprise, they use the same bats as righties. And we don’t have different pens for lefties. Or tennis rackets. Or cutlery. So why are right-handed and left-handed scissors so different?

For our answer, we need to get a bit sciency. Scissor design looks simple enough but there are a lot of smart mechanics, as well as ergonomics at work. For one thing, scissors are not symmetric – the blades don’t just magically meet in the middle; they overlap. 

(The good news is that traditional craft scissor makers are more attentive to lefties and if you look closely, you can find left-handed products. We want to make sure both hands get equal opportunity to feel what heritage quality feels like in action, the way they are supposed to work.) 

Wrong-handed scissors push the blades apart, instead of together

OK, back to the science, physics to be precise. Scissor blades move cleanly in a vertical fashion. Meanwhile, your thumb pushes out from the palm of your hand and gives it a lateral pressure while the fingers pull inwards. With a right-handed pair of scissors the right thumb blade is closer to your body and pressure is exerted to push the blades together.

Right-handed scissors are engineered to harness this motion to push the blades together, but when used in the left hand, the blades are pushed apart,” explains Paul Jacobs, co-owner of craft scissor maker Ernest Wright in the English town of Sheffield.

The weird thing about scissors is, often lefties just put up with it. Okay, to be honest, historically a lot of lefties were just forced to write with their right hands and to stop being ‘different’. (If you want to dig deeper, this mess is a good example of how dominant forces in society marginalize minorities.)

If you don’t use quality scissors very often (at Ciselier, we feel sorry for you), and just need to snip a piece of string, then a lefty won’t really mind using the wrong design. But if you are left-handed and doing crafts, or embroidery or tailoring or upholstery or any number of activities that require precision and ergonomic comfort, it’s time to get the right scissors. It’s time to use scissors the way they are supposed to work.

Some great lefty quotes

“Two and a half thousand left-handed people are killed every year using things made for right-handed people.”

Maggie O'Farrell, The Vanishing Act of Esme Lennox

“Are you really left-handed?” Mr. Marshall asked. “No. I’ve just been pretending to use my left hand my entire life because I enjoy never being able to work scissors properly.”

Courtney Milan, The Suffragette Scandal

Semi vs true: Will the authentic left-handed scissor please stand up please
You only have one left hand, but oddly enough there are two kinds of left-handed scissors. It’s not because you’re special, even though people have made the case that lefties are smarter, or more creative or better leaders. No, there are two kinds of left-handed scissors because manufacturers just decided at first to meet you half way.

Let’s start with the semi left-handed pair of scissors. The ‘semi’ addresses only part of the challenge; that being the finger grips, which are reversed for easier opening and closing by lefties. But a person’s sightline is still obscured by the position of the blades. 

In order to give a left-handed cutter a clear view of the actual cut, the blades need to be reversed as well. That requires a full mirror image of the right-handed pair. This is called a ‘true’ left pair of scissors and before 1970 you’d be unlikely to even find a pair.

You will also see scissors that are sold as ambidextrous, with symmetric handles that make no distinction between the handles of the thumb and finger handles. With these scissors, there is a very strong pivot and the blades don’t have any lateral give.

Even here, most "ambidextrous" scissors are still right-handed in that the upper blade is on the right and that creates the same problem with sightlines for left-handed users of right-handed scissors.

We have personally never held a pair but there are actually true ambidextrous scissors as well. Under  U.S. Patent 3.978,584 a design calls for double-edged blades and one handle that is swung all the way around (to almost 360 degrees) which means the  back of the blades does the cutting.

Did you know? Left-handed trivia 

Whether you are celebrating International Left-Handed Day (August 13th) or just needed to know: 

  • Recent US presidents Bill Clinton, Ronald Reagan, George H.W. Bush and Barack Obama were all lefties. As were Marie Curie, Albert Einstein, Linus Pauling, Albert Schweitzer and Janis Joplin. (So is one of my sisters, who shall remain anonymous but was recently sent a lefty pair of scissors.)
  • Prince William, likely future king of England, is left-handed and so was his great-grandfather George VI. We don’t get too excited about royalty but raise this because the latter’s father, George V, actually forced his son to switch to writing with his right hand. Rather mean, right?
  • Throughout history, in addition to the myth of being smarter, accusations have flown that lefties are clumsy, bewitched, die younger (see the quote above about the dangers of living in a right-handed world) and many other things. Science does little to back these myths up. 
  • In baseball, left-handed batters (who may write right-handed) make up about a third of all batters. ‘Southpaws’ (left-handed pitchers) are between 20 and 25%, about twice the rate of left-handedness in the general population. So the odds are, if you are lefty – and can hit and throw well – you have a better chance of making it to the big leagues.

You’ve missed another point. Although I appreciate you describing the Siteline benefit of using a true lefty scissor, as a lefty who grew up learning on righties in my left hand, I cannot for the life of me get anything CUT with a true lefty scissor. the paper and fabric bend—once you have gotten used to the angle to hold the scissors, you can’t convert to a true lefty scissor. I have 2 great quality lefties that I am now officially getting rid of and my google search today is to find what the other type of lefty is called so I can go buy—a semi lefty.

My brother kindly gifted me with left-handed pinking shears for Christmas my senior year of high school, after I’d been sewing and cutting with right-handed scissors for 6 years. Accustomed to looking over the blades to see the cutting line, I found I was mis-cutting, and I exchanged them for a right-handed pair. Too late to retrain me!? When I taught my left-handed Goddaughter to sew, I started her on left-handed scissors. I’m tempted by these semi-left-handed scissors that were just highlighted in the Fall 2023 Threads magazine.

I am right-handed, so I learned to use the mouse with my right hand. Later I regretted it, because I had a lot of text editing to do, and it would have been easier to move the cursor with my left hand and write with the right one. It was too late to change the habit and I move the mouse (cursor) with my right hand, raise my hand an type, then grab again the mouse and so on.

One thing you forgot. Righties sometimes need to use left-handed scissors. There are some tasks whose geometry require using the left hand to make the cut. Or the more difficult job is holding/arranging some tricky item that needs cutting, and cutting is the easier job (so gets the left hand).

I’m a righty who wishes I had a pair of lefty-scissors for these kinds of tasks.
