The Sentry is a weathered dark blue hilt with intricate milled detailing on the emitter and grip. The grip alse features a removable sleeve for optional styling. Its unique design is both sinister and elegant, making it stand out from other lightsabers. The silver detailing also gives it a luxurious feel and contrasts the brushed/weathered look. 

The weathering process reveals some of the blue tones as it thins out the darker finish. Colours do vary from hilt to hilt.
