Left handed scissors
Yeah, my father was born left handed but my grandmother 'switched' him. Late in her life, she told me she was 'probably wrong' to do that but that was the conventional wisdom in the 1930s. My first grade teacher wanted to 'switch' me but my mom and the school principal overruled her. This was considered new and progressive thinking in 1970. Dad's conversion to right-handedness was so thorough that he couldn't teach me how to tie a necktie, not that he had the patience to teach me much of anything. Fortunately, he had a first cousin who was left handed and taught me how to tie a necktie in about a minute.
The first time I realized I was left handed was when I was in kindergarten and got supremely frustrated when I couldn't use conventional scissors with my right hand. I had undiagnosed ADHD at that point, so patience was not in abundance for me back then. I did eventually get some 'lefty' scissors and things were much better but somewhere along the line, I learned to use right-handed scissors and I'm fine, once I get them in the proper hand. Of course, about half the time, I pick them up with my left hand and momentarily wonder why they don't work very well.
Update on the butter knife—After perusing eBay for about the millionth time, I found and bought something I'd never seen before—a butter knife on which the handle is twisted 90 degrees so it's now perpendicular to the blade. Not sure if that was done by the manufacturer or was an 'aftermarket' modification, but it appears to now be equally usable with either hand. It doesn't match any pattern of flatware I own, but I don't give a rip. In this case, functionality reigns supreme. I usually buy butter in tubs and spread it with a table knife but next time I'm at the grocery, I'm buying it in sticks, just so I can try this modified knife out.
For you right-handers who don't understand what I'm on about, take a close look at your butter knife. Most likely, the blade is asymmetrical and offset from the handle. These two design elements together make most butter knives next to impossible for left handed use. Ever since I was an adolescent, it was quite apparent to me that either eliminating the offset and/or making the blade symmetrical would alleviate the problem.
