is there some accurate tool for that task ?
Yes there is. It's called a steady hand and a good eye

I have done this on maybe 10 occasions over the years and have been satisfied with the results MOST of the time. And I am legally blind in one eye

really I am. They told me I was wasting my time trying to learn to fly R/C. That was 23 years ago and I'm still going, even have a few trophies
Try it, it's not hard at all and plywood is cheap, at least where I live.
