What an awesome piece!

I just opened my GITD Culprit X and it exceeded my expectations. It was thicker and more durable than expected. It also glows in the shade with plenty of daylight around. In a dark room it's impressive. Would 100% recommend 5 out of 5 stars

I've had nothing but great experiences with Koch Tools

I've had nothing but great experiences with Koch Tools. I absolutely love their beads and toads—they're high quality, unique, and a perfect addition to my EDC collection. Shipping is always fast, and the discounts make it even better. Highly recommended for anyone looking for quality gear and excellent service!
