A forceps includes a housing including a shaft. The shaft includes an end effector assembly having a pair of curved jaw members. The jaw members include an electrically conductive surface and a curved blade channel having opposing sidewalls. A cutting blade is configured for translation within the blade channel. Proximal portions of a first sidewall include incident angles of less than five degrees that engage the cutting blade and direct the blade towards a specific point of contact on the opposing sidewall of the curved blade channel.
