Kershaw Launch 4 1.9in Automatic Folding Knives by Kershaw Originals Review

Reviewing the Kershaw Launch 4 1.9in Automatic Folding Knives by Kershaw Originals: Beyond Marketing

As an equipment specialist with over a decade of practical experience across diverse environments, from dusty workshops to pristine labs, I approach new gear with a healthy dose of skepticism and a deep appreciation for real-world performance. The Kershaw Launch 4 1.9in Automatic Folding Knives by Kershaw Originals caught my eye not just for its automatic deployment, but for its compact size, a feature often overlooked in the pursuit of larger, more imposing blades. My immediate need was for a discreet, legal-carry option that wouldn’t compromise on Kershaw’s reputation for quality, especially for everyday tasks that don’t require a full-sized combat knife. My first impression upon handling it was one of immediate satisfaction; the anodized aluminum felt solid yet incredibly light, and the overall build quality hinted at the precision I’ve come to expect from Kershaw. I had briefly considered other small automatics from brands known for their rapid deployment, but the specific combination of CPM 154 steel and Kershaw’s design philosophy drew me to this particular model. It offered a promise of compact functionality that felt both practical and satisfyingly well-engineered.

Real-World Testing: Putting Kershaw Launch 4 1.9in Automatic Folding Knives by Kershaw Originals to the Test

First Use Experience

My initial testing grounds for the Kershaw Launch 4 1.9in Automatic Folding Knives by Kershaw Originals were primarily urban and light outdoor scenarios. This meant opening mail, breaking down cardboard boxes for recycling, and occasionally slicing through zip ties during workshop reorganization. I also carried it in my pocket for a week, noting its presence (or lack thereof) during daily activities. The automatic deployment was astonishingly quick, a fact that required a slight adjustment period; you definitely need a secure grip. Moisture from a sudden shower didn’t seem to affect its operation, and the lightweight aluminum handle remained comfortable even after extended handling. The low-profile push-button lock was intuitive to use, and I appreciated its subtlety.

Extended Use & Reliability

After several months of consistent, albeit light, daily use, the Kershaw Launch 4 continues to impress. It has proven remarkably durable for its size, with no noticeable play in the blade or any signs of wear on the anodized aluminum handle. The CPM 154 steel blade has held its edge exceptionally well through countless box-opening duties and general utility tasks. Maintenance has been minimal, requiring only a quick wipe-down with a soft cloth and occasional lubrication of the pivot, which is straightforward thanks to its accessible design. Compared to other small automatics I’ve used, this knife offers a superior balance of rapid deployment, edge retention, and overall build quality without the heft that can make some knives feel cumbersome.

Breaking Down the Features of Kershaw Launch 4 1.9in Automatic Folding Knives by Kershaw Originals

Specifications

The Kershaw Launch 4 1.9in Automatic Folding Knives by Kershaw Originals boasts a compact overall length of just 5.1 inches, with a closed length of 3.2 inches and a slender 1.9-inch blade. This short blade is a significant factor in its legal carry potential in many jurisdictions, a key design consideration. The blade itself is crafted from CPM 154 steel, a powdered metallurgy alloy renowned for its excellent balance of toughness, wear resistance, and corrosion resistance. This translates to a blade that can handle everyday abuse while maintaining a sharp edge for extended periods.

Complementing the blade is a handle made from 6061-T6 Aluminum, which contributes significantly to the knife’s incredibly low weight of just a few ounces. This material is not only lightweight but also remarkably strong and resistant to the elements. The handle features a durable Cerakote finish, which enhances its grip and provides an additional layer of protection against scratches and wear.

The knife employs an automatic opening mechanism activated by a low-profile push-button lock. This design element is crucial for safety, making accidental deployment less likely than with some other automatic knife designs. The spear point blade shape is a classic choice, offering a good balance of piercing capability and slicing efficiency for general utility tasks. The knife comes with a single-position pocket clip, specifically configured for a right-hand, tip-up carry, ensuring it remains securely and discreetly accessible.

Performance & Functionality

In its primary role as a compact cutting tool, the Kershaw Launch 4 performs exceptionally well. The CPM 154 steel blade is a standout feature, delivering impressive sharpness out of the box and retaining it through consistent use. I found it easily sliced through thick cardboard and packaging tape without any noticeable dulling. The automatic deployment is impressively fast and positive; with a firm press of the button, the blade springs out with authority, ready for immediate use.

The primary strength of this knife lies in its legal-carry potential, making it an excellent choice for urban environments or areas with strict blade length regulations. It excels at everyday tasks where a larger knife would be conspicuous or impractical. Its main limitation, inherent to its size, is that it’s not designed for heavy-duty prying or chopping tasks where a more robust blade and handle would be necessary. For its intended purpose of quick, convenient, and legal cutting, it consistently meets and often exceeds expectations.

Design & Ergonomics

The Kershaw Launch 4 truly shines in its design and ergonomics, especially considering its automatic nature. The anodized aluminum handle feels secure and comfortable in hand, despite the knife’s diminutive size. Its lightweight construction is a major ergonomic advantage, making it easy to carry all day without adding noticeable bulk or weight to your pocket. The low-profile push-button lock is cleverly integrated, minimizing the risk of accidental activation while remaining accessible for quick deployment.

The spear point blade has an aggressive yet functional profile, and the DLC coating on the blade not only adds to its aesthetic appeal but also provides a sleek, non-reflective finish. The single-position pocket clip is securely mounted and allows for a discreet, right-hand tip-up carry, which I found to be optimal for quick access. The overall build quality is testament to Kershaw’s manufacturing prowess; there is no blade play, and the action is consistently smooth.

Durability & Maintenance

Durability is a strong suit for the Kershaw Launch 4. The CPM 154 steel is inherently resistant to corrosion and wear, meaning the blade should maintain its integrity and sharpness for a very long time. The 6061-T6 Aluminum handle is also incredibly resilient, capable of withstanding everyday bumps and scrapes without showing significant damage. The Cerakote finish on the handle further enhances its scratch resistance.

Maintenance for this automatic folder is refreshingly simple. Beyond occasional cleaning with a soft cloth to remove debris, the pivot can benefit from a drop of knife lubricant to ensure the automatic action remains smooth and responsive. Unlike some other automatic knives, there are no complex mechanisms to worry about or specialized tools required for basic upkeep. Its robust construction suggests a long service life for those who use it within its intended parameters, making it a reliable tool for daily carry.

Accessories and Customization Options

The Kershaw Launch 4 1.9in Automatic Folding Knives by Kershaw Originals is a straightforward tool, and as such, it comes with its essential accessory: a single-position pocket clip. This clip is crucial for secure carry and easy deployment, ensuring the knife is always at the ready without being obtrusive. While the knife itself is not designed for extensive customization in the way a modular system might be, its design focuses on refined functionality out of the box.

There are no other included accessories, which is typical for a knife of this category. However, the CPM 154 steel blade can be easily sharpened using standard sharpening systems, allowing users to maintain its razor-sharp edge. For those who prefer a different carry style, aftermarket pocket clips compatible with Kershaw knives might exist, but the included clip is well-designed for its intended purpose. The focus here is on the knife’s inherent quality and performance rather than extensive add-ons.
