Review on 🛠️ Improve Precise Stair Cutting with Stair Tread Template Set for Colins: Replacement Steps Risers Clamp Plates, Shelf Scribe Layout Tool, and Caliper Gages by Shane Bullion

No, you can't just cut steps or risers at 90 degrees. A million to 1 the room is perfectly formed with 90 degrees left and right. With this tool, you can easily copy the left and right angles, which are almost always less than 1 degree, and transfer that angle AND the length to wood or other cutting media. Align the blade with the line and cut. Advice for indoor or enclosed steps and risers. That is, the end is not visible. Make your cut so that all cutting parts are removed. If you cut the right side marker outside of the marker, your length will be too long. It won't fit. Remember I'm talking about 64s and 128s. It doesn't sound like much, but the difference is big.
