XIKARs Xi series of cutters are world renowned. So when they introduce a cutter without the iconic teardrop shape, you can rest assured the Ultra has passed strict tests for sharpness, quality style. A 64 ring gauge and as thin as a few credit cards, (only 3.5mm thin!) the Ultra will fit any occasion. As useful as any Xi cutter, this cutter comes with magnetic attachment system to adhere to Xikars Ultra Single Flame lighter. The Ultra Cutter and Lighter can be purchased together or separately at NeptuneCigar.com.
