No they are not. Ultra reverse blades have a tooth that is reversed every third tooth down the course of a blade. Reverse scrollsaw blades have a small section on the bottom of the blade of about 5 to 7 teeth that are reversed. The object of a reverse tooth is to limit the fuzzies on the back side of a piece when cut. means less sanding. A standard blade is stamped and you will notice the teeth have a taper to the right when looking at the blade head on. Ultra blades are milled and that means the teeth have a tendency to point both ways in an alternating fashion. These are suppose to be sharper because the way they are produced. Same as a bandsaw blade. They make a large assortment of blades for various thickness and hardness of woods, metal, acrylics that you are cutting. They also have spiral blades and these are difficult to learn to cut with unless you learn with right from the start. I do not like them. These blades will cut anyway you move the work piece into them. Can be daunting for beginners. I suggested the Penguin silver reverse because they are a nice blade that has a double tooth pattern and then a space which allows for saw dust to clear the kerf and with the reverse teeth on the bottom it does not grab the work piece and slam it up and down which at times ultra reverse teeth can do if you are not use to them. As I say I have been using the #5 penguin silver reverse blades for many many years. I cut mainly red oak, walnut and maples in 1/4" to 3/4" I get nice clean cuts. Speed and tension are very important and the more she uses the saw the more she will become familiar with what is right. If you click on the link I provided it will show you a profile of each blade. The name is one thing but the actual photo of the blade will tell the story.
The link I posted is where I buy my blades from. Mike Moorloch was the originator of those blades and he sold the business before he past away. I was a good friend of his and he used me to test many of his blades. These blades are made in Germany. The other big name in scrollsaw blades is Pegas which are Sweedish blades. Then you have many offshoot blades such a Delta, Olson and many more. People love to try different brands, styles, and sizes till they find a comfort blade. You may want to get a variety pack for trial.
