However, its primary focus on self-defense might make it less appealing for those solely seeking a writing instrument.

The Atomic Bear Tactical Pen is a sturdy, well-crafted self-defense tool that doubles as a smooth-writing ballpoint pen. Made from military-grade aluminum, it feels solid and balanced in hand, which is great for both everyday writing and using its glass breaker tip in emergencies. Its ribbed grip helps prevent slipping, making it comfortable to hold during extended use or in stressful situations. At about 80 grams and nearly 8 inches long, it’s a bit heavier and larger than a regular pen, but this adds to its durability and impact power.

Unlike many tactical pens that struggle with writing, this one provides a smooth and consistent ink flow and accepts several popular refill brands, so you won’t have to sacrifice writing quality for toughness.
