Here at Adept Knives, we're impressed with the Kershaw Launch 4, a compact and capable automatic knife. This knife is legal to carry in many places, but always be sure to check your local regulations before carrying any automatic knife. The Launch 4 features a 1.9-inch blade made from CPM 154 steel. CPM 154 is a high-performance steel that offers a good balance of hardness, edge retention, and corrosion resistance. The blade is coated with Cerakote, a ceramic-based finish that enhances durability and wear resistance. The handle of the Launch 4 is made from anodized aluminum. Anodization is an electrochemical process that creates a hard, protective oxide layer on the surface of the aluminum. This makes the handle more durable and scratch-resistant. The Launch 4 weighs only 1.8 ounces, making it a lightweight and comfortable option for everyday carry. Overall, the knife is 5.1 inches long, making it a good size for both pocket and bag carry. Customers on the Kai USA website have rated this knife 4.6 stars out of 5, with many reviewers praising it as a great everyday carry (EDC) knife. However, one reviewer reported that the spring on their knife broke after a few months of use. It is important to note that any knife can break if it is not used or cared for properly. Overall, the Kershaw Launch 4 is a great option for those looking for a compact, lightweight, and capable automatic knife for everyday carry. With its high-quality materials and construction, the Launch 4 is a knife you can count on for years to come. Stop by Adept Knives today and see for yourself why the Launch 4 is a great choice for your EDC needs.
