Read on for some CPM 154 facts and reasons users are raving about the Urban in G10.  Pictured from top to bottom are the Triple Black, the OD Green, and the Milspec models.

CPM 154 Blade Steel: Quick Facts

• CPM 154 is made by Crucible Industries. For the steel nerds, here is the full data sheet.

• Crucible Industries is a legendary American steel manufacturer with over a century of experience. They hold numerous patents on their products and methods – as far back as 1905.

• The CPM stands for “Crucible Particle Metallurgy”, which is is a method of producing higher alloyed grades of superior quality than could be accomplished through conventional steelmaking.

• Crucible took 154CM and improved it with their Crucible Particle Metallurgy (CPM) process to make CPM 154.

• It has much finer grain than the original 154CM, which results in improved toughness and edge retention.

• It looks good and is easy to sharpen.

• Because it has Chromium and Molybdenum in it, you can get a really nice polished finish (which is exactly what we did on the Milspec model).

Boot and neck knives are popular with those wanting an easily concealed weapon ready in a moment. They date pretty far back; from Civil War soldiers, to outdoorsmen, to gangsters. Whether you need something to make you feel safe walking downtown, or a last ditch defense against a bear attack, having the DPx HIT Dagger at the ready is a great idea. Why? Because it has all of the classic attributes sought after in a boot knife, with a few modern touches.

Experienced boot knife users opt for the following features:

• conceal-ability
• light weight
• quality blade steel that holds an edge
• ergonomic handle, for confident grip
• stabby blade design

The DPx HIT Dagger checks all of the boxes when it comes to having the features that make a good neck or boot knife.

It is a compact, lightweight push dagger made in Italy by LionSTEEL and comes with a black leather sheath and adjustable chord/lanyard. You can use the lanyard and eyelets to secure the sheath to a boot or inside a concealed area of your choice. The easy to use sheath simply snaps open and closed, while the flat surface sits nicely and does not rub.

Blade steel is important because it directly influences performance, durability, and overall reliability of knives. Among the growing list of options available, Sleipner blade steel remains an exceptional choice for tactical folding knives.

Here’s why Sleipner is still a heavy hitter among knife enthusiasts and professionals alike:

The Facts From Sleipner’s Manufacturer

Uddeholm Sleipner is a chromium-molybdenum-vanadium alloyed tool steel which is characterized by:

• Good wear resistance
• Good chipping resistance
• High compressive strength
• High hardness (>60 HRC) after high temperature tempering
• Good through-hardening properties
• Good stability in hardening
• Good resistance to tempering back
• Good WEDM properties
• Good machinability and grindability
• Good surface treatment properties.

1. Exceptional Edge Retention

One of the primary attributes of Sleipner steel is its remarkable edge retention. This means that a knife with a Sleipner blade stays sharp longer, even after extensive use. This quality is particularly crucial in tactical scenarios where the reliability of your knife can be the difference between success and failure. Whether cutting through tough materials or performing precision tasks, a knife that maintains its edge is indispensable.

From the maker’s website profiling Sleipner’s edge retention qualities:

Uddeholm Sleipner is a general purpose steel for cold work tooling. It has a mixed-abrasive wear profile and a good resistance to chipping. Furthermore a high hardness (>60 HRC) can be obtained after high temperature tempering. This means that surface treatments such as nitriding or PVD can be made on a high strength substrate. Also, it means that complicated shapes with hardness levels >60 HRC can be wire EDM’d from blocks with relatively thick cross-sections with a much reduced risk of cracking

2. Superior Toughness

For military personnel, first responders, and outdoor adventurers, a tough blade is a must-have in their toolkit.  Sleipner steel is engineered to withstand heavy-duty use without chipping or breaking. This toughness ensures that the blade can handle rigorous tasks, such as prying, chopping, and batoning, without compromising its structural integrity.

3. Excellent Wear Resistance

Wear resistance refers to the steel’s ability to withstand abrasion and general wear over time. Sleipner steel boasts high wear resistance, which means the blade remains in top condition longer, even under harsh conditions. This durability is essential for a tactical folding knife, which is often exposed to dirt, grit, and other abrasive elements that can degrade the blade’s surface.

4. Corrosion Resistance

Sleipner offers a respectable level of corrosion resistance, especially when properly maintained. Tactical knives are frequently exposed to moisture and corrosive environments, so having a blade that resists rust and corrosion helps extend the knife’s lifespan and reliability. Regular cleaning and oiling can further enhance this property, ensuring that the blade remains functional and dependable.

5. Ease of Sharpening

A blade is only as effective as its ability to cut.  Despite its hardness and edge retention, Sleipner steel is relatively easy to sharpen. This characteristic is crucial in tactical situations where a quick touch-up in the field may be necessary. The ability to restore a razor-sharp edge with minimal effort ensures that the knife remains a reliable tool throughout its use.

6. Versatility and Performance

Sleipner steel offers a balanced combination of hardness, toughness, and wear resistance, making it versatile for various applications. Whether you’re using the knife for cutting, slicing, piercing, or more demanding tasks, Sleipner steel performs exceptionally well. This versatility is a key advantage for tactical folding knives, which need to be adaptable to a wide range of scenarios.

7. Proven Track Record

Sleipner steel is developed by Uddeholm, a renowned name in the steel industry with a long history of producing high-quality tool steels. This pedigree ensures that Sleipner steel benefits from advanced metallurgical processes and stringent quality control, resulting in a reliable and high-performance blade material. Previous DPx Gear knife models that have used this steel are a testament to its effectiveness, adding to its credibility as a top choice for tactical knives.

Conclusion

Avoid fads and hype.  Choose a tactical knife that uses a steel with a proven track record and reliable when it counts.

Sleipner blade steel, with its excellent edge retention, toughness, wear resistance, and ease of sharpening, offers a well-rounded solution for demanding users. Its versatility and long-standing reputation make it a superior choice, ensuring that your tactical folding knife performs reliably in any situation. Whether you’re a professional in the field or an enthusiast seeking a robust tool, a knife with a Sleipner blade is a worthy investment.
