Compare the Soileater V3 tourniquet holder and Black Triangle S4 knife to see which tactical gear fits your carry style, environment, and budget.
Quick Answer
Choose the Soileater V3 if you need a versatile, ambidextrous tourniquet holder for belts or MOLLE. Pick the Black Triangle S4 if you want a discreet, pocket-friendly knife for non-permissive environments.
Different Jobs, Different Trade-Offs
These two pieces of tactical gear solve different problems. The Soileater V3 is a medical accessory built to keep a tourniquet accessible and secure. The Black Triangle S4 is a backup blade designed for low-profile carry when a gun isn't an option.
Your choice depends on what gap you're filling. If you already carry a tourniquet loose in a pocket or bag, the Soileater V3 adds organization and quick access. If you need a last-resort tool in a no-gun zone, the S4 gives you a blade without printing.
Price also separates them: the Soileater V3 sits at a lower price point, while the Black Triangle S4 costs more, reflecting its multi-knife design heritage.
Carry Style and Environment Matter
The Soileater V3 mounts on MOLLE or a belt with one-wrap, and its ambidextrous design works for left- or right-handed users. It's overt gear—visible when worn on a belt—which is fine on a range or in the field.
The Black Triangle S4 is built for concealment. Its sheath hooks for pocket carry and comes with a Raven Concealment IWB Overhook, so it can ride inside the waistband. This makes it a better fit for non-permissive environments where open carry isn't allowed.
Think about where you'll actually use the gear. If you're always in a duty belt or plate carrier, the Soileater V3 integrates smoothly. If you're moving through urban spaces or workplaces with restrictions, the S4 stays hidden.
