Everyone is different. So, this is not anything but information. I have cut my rubbers with a blade as in the video, I have seen people use various versions of razor, scalpel, xacto....I have seen people who use scissors.
For a long time I cut with a blade. When I played at this club in NYC's Chinatown, I remember watching the guy who ran the club cutting with scissors. It was really effing fast and his cuts always came out perfect. As good as those cuts with the blade. Mine never did. But I did learn that, there were two things with cutting with a scissor.
1) Starting: you have to know how to start the cut to avoid the handle.
2) Practice: if you have done enough of them, and you have seen someone who knows how to do it, maybe getting a few tips, you can get decent at it.
Again, my cutting never looked perfect. But for me, I never cared if it looked perfect. For me, the fact that it took 1/8th the time to cut with scissors and was pretty darn good--neat enough--was good enough for me. All you need to cut with scissors, is a good sharp scissor. You don't need a special scissor. You don't need one with a curved blade. A good sharp scissor is all you need. A little oil on the scissor will help just like it will with a scalpel or a sharp hand held razor like the one in The_TT_Bat_Guy's video, or the scapel cut that NDH showed.
The video is good: if you want the cut to be as close to perfect as you can get as soon in your TT playing as possible, go that way. If you are willing to have the cut not quite as perfect until you really master how to cut with scissors, but have the cut need no extra equipment, no cutting surface, and done once and done, scissors work well also.
It really depends on the person.
To start out the cut with a scissor:
a) You need to have the scissor angled so the scissor handles are not in the way of the blade handle; they can be angled so that they are below the handle and pulling the rubber a little down towards the blade, or the opposite.
b) Until you are fully past the handle, you need to make tiny cuts; if you use the part of the scissor near the handle so the scissors are opened, it is easier, if you are closer to the tip of the blade as you cut, it is harder to cut.
c) Once you are past the handle being in the way, it is easy until you get near the wing and handle at the end of the cut. Then you may need to go back to little cuts and an angle that lets you avoid having the blade and handle get in the way of each other.
So, it does take technique. There are some things that make it much easier if you see someone who is good at it do the cutting and can learn those details that make the scissor work well. But if you get those skills under your belt, it is a very easy way to cut and with very little fuss and hassle.
I do believe there are some good videos on cutting with scissors. 10-15 years ago, I know there were several.
So, as long as people know that there are pros and cons to using either scissors or a blade, then you can make the choice that suits you best.
