The transformation option with only one side clamped metal blade is extremely handy and works well. However, the first reconstruction was not without tools. The clamping lever with which excited the saw blade and the conversion is initiated, I had to make consistently. With hand strength could I move nothing. The same applies to the fixed screws for clamping of the saw blade. After Consistently Make now everything goes without tools.
The vulnerability of the saw seem to have the pins that hold the metal blade tension. The relatively thin pins form one piece with the red parts of the saw. In the normal metal saw these pins are removable and replaceable. And I had to replace the already occasionally times. This saw then must therefore be reversed, if there are spare parts at all.
The supplied blade has a good quality. Because of the weak points but the still very good value for money only one star deduction.
