This set cuts on the “push stroke”and all the blades are sharp, flat and will cut wood and plastic.

The two rectangle Thin and Fine kerf blades have 52 and 32 teeth per inch and a reinforcing metal strip opposite the teeth keep the blade as thin as possible without flexing.

The triangular “Saber” and tiny “Keyhole” blades both feature 24 teeth per inch. The whole set will fit carefully in a quart resealable bag. I needed a screwdriver to loosen all 4 blades which ship “stacked” and screwed together.
