You make a good point here. Different tools for different uses. While working on the Millennium falcon, I found that I had to use the dental pick to do some scoring. Nothing else would get in to the tiny nooks I needed to.
I will give that exacto another try. It is much cheaper than the tamiya tool and I am more use to hold it. That particular knife in the video is 32 years old and I have used it all of those years. It just feels right.
As for the dyno tape, I have used it on curved surfaces before. Yes it isn't as thick as I would like, but it does have a sticky side, which allows me to put it on the model and not worry about tape coming up. It will also bend around the curve of say a plane fuselage just fine. I have used it for this before.
I do have a lot of styrene strips, so maybe in the next video I can compare those two methods......
