The Mammut Crag HMS Slide Lock Carabiner is a locking carabiner for all types of climbing. The lock slides with just one hand, utilizing your thumb and forefinger to open up the gate. This prevents accidental opening for increased safety on the ropes. If you ever retire this biner I bet it'd be really fun to open & shut, annoying those around you in the office.
