An electrode adapted to connect to an electrosurgical instrument is provided. The electrode includes a proximal end that is adapted to connect to an electrosurgical instrument and an electrosurgical energy source. The electrode includes a distal end configured for treating tissue. The distal end of the electrode includes a first portion having one or more edges and a second portion having a substantially blunt profile. An insulative material is disposed over at least the distal end of the electrode. The insulative material includes a first thickness at the first portion and a second thickness at the second portion, wherein upon activation, the insulative material disposed over the first portion breaks away from the first portion allowing energy to travel to tissue from the first portion.
