A t-shaped blade 20 for an oscillating power tool comprising an elongate body 22 fixed to an attachment section 24, the elongate body is divided into two or more resiliently flexible tongue portions 32/34, each tongue portion comprising a cutting portion distal from the attachment section. The tongue portions may be disposed in a common plane and the elongate body may have a longitudinal length extending from the attachment section to an outer edge of the cutting portion, each tongue portion having a length between 30-80% of the longitudinal length. The body 22 may be between 0.5-3mm thick and may comprise at least one slit 36 with the portions 32/34 either side. There may be two or three slits to provide three or four tongue portions respectively. The cutting portion may comprise a circular arc and/or an abrasive material, and the blade may be formed from carbon steel. A depth stop may be attached to the elongate body and secured to at least two tongue portions. A method of using said blade is provided comprising activating a power tool, inserting the blade into a material-filled channel and twisting the tool to engage the tongue portions with walls of the channel.
