An accessory for a power tool, comprising:

• an axis of rotation about which the accessory is configured to rotate;
• a blade;
• and
• a coupling, including:
• a blade portion fixedly coupled to the blade;
• a tool portion configured to be removably coupled to the power tool, the tool portion including an opening arranged about the axis of rotation;
• and
• a transition extending between the blade portion and the tool portion, the transition including a first transition region where the transition intersects with the blade portion, the transition including a second transition region where the transition intersects with the tool portion, wherein:
• the first transition region includes a first arc having a center that is arranged between the first arc and the axis of rotation,
• the second transition region includes a second arc having a center that is arranged between the second arc and the axis of rotation,
• the blade portion has a first blade portion end that is adjacent to the transition and a second blade portion end that is opposite the first blade portion end and is not adjacent to the transition,
• the first blade portion end has a first blade portion width and the second blade portion end has a second blade portion width that is different than the first blade portion width, and
