    		 This V-cut ground electrode comes under a variety of names depending on manufacturer. Although they look the same, it may be called a tapered cut ground, trimmed side electrode, wedge shaped ground, tapered V-profile or an inverted V-tip ground. All have the same purpose, to reduce quenching and shadowing.
