Review on Precisely Irregular Duplicator Construction Woodworking by Tom Tucker

This is one of those tools that you won't use too often unless you're a carpenter. The fact is you REALLY need this thing every once in a while, and when you don't have one you ruin everything or make 10 cuts to fit a piece of tile around the pipe. It makes things easier and this one in particular is a massive improvement over my old one. First it comes with a small one (the big one can't help if the area is too small) and a big one. The biggest difference is that my old whistle needs to be looked at closely as it has been dropped many times and an extra blade or two added and you would get incorrect measurements. This is not a problem, it creates a perfect whistle print and allows you to get your haircut perfect, so I have to give 5 stars for VALUE + PERFORMANCE + EASY TO USE
