Wow, arrived in a padded soft case... plush lining with two internal knife slots, and one external. Includes a hook & loop with a TK patch. Typical TacKnives quality with excellent double action release... it was a bit tight at 1st, but seemed to loosen with a few flicks. Just beware your index finger position... not that I think it's a serious problem. A great a addition to my EDC and work box opener. Includes 4 additional blades. https://youtu.be/6ZlQCIKZ-aw?si=f5yWhTnao-ruO-oT

This is the second version I've bought so far. Loved the first one so much I had to try a different handle. Feels very tough and I love the action on this model. Very quick to deploy and retract. Comes with a very nice little case also.
