This is a super sturdy step stool make from a single 2x4 stud. It's made with interlocking half-lap joints set at an angle. So you'll most likely want to use a dado stack in your table saw, although you can certainly make this with a regular saw blade. The project is a bit challenging, but if you just follow the plans and set up your cuts carefully, you'll be thrilled with the result!

Note: When you purchase these plans, both the U.S. and metric versions will be available to download after you check out.
