S30v vs. CPM154 | What’s Best To Choose?

The possibilities are daunting when selecting the ideal steel for your knives. S30V and CPM154 are two popular blade options among knife lovers. In this tutorial, we’ll go over the distinctions of s30v vs cpm154

These two steels are so you can decide about your next knife purchase.

Understanding of S30V vs CPM154:

Before we begin the comparison, let’s first define S30V and CPM154.

S30V steel

S30V, developed by Crucible Industries with famous knife manufacturer Chris Reeve, is a premium stainless steel with outstanding edge holding and corrosion resistance.

It comprises carbon (1.45%), chromium (14%), vanadium (4%), and molybdenum (2%), which provide a good mix of edge retention, toughness, and corrosion resistance.

CPM154 steel

Crucible Industries produces CPM154, a powdered metallurgy stainless steel recognized for its superior edge holding and ease of sharpening. Its composition is comparable to S30V but with less vanadium (3%) and more molybdenum (4%) for increased toughness and machinability.

Common ApplicationsHigh-end knives, tactical knivesHigh-end custom knives, culinary knives

Edge Retention and Sharpness:

S30V steel has excellent edge retention but is fairly difficult to sharpen because of its hardness.

CPM154 also has great edge retention but is easier to sharpen than S30V, making it a better alternative for individuals who value the simplicity of maintenance.

Toughness and Durability:

While both steels are noted for their hardness, CPM154 has superior impact resistance and is less prone to chipping, making it a dependable choice for heavy-duty applications.

Corrosion Resistance:

S30V and CPM154 have good corrosion resistance due to their chromium concentration. Due to its increased chromium content, S30V may have a modest advantage in resisting corrosion in severe situations.


Knives manufactured with S30V steel are often more expensive than those made with CPM154. However, the price difference might vary based on knife design, brand, and extra features.


Which steel is best for everyday carry knives (EDCs)?

S30V and CPM154 are great EDC knives owing to their mix of edge holding, corrosion resistance, and durability. However, if you want a steel that is simpler to sharpen, CPM154 might be a better choice.

Which steel holds a finer edge for longer periods?

Both S30V and CPM154 are known for their remarkable edge retention. However, S30V is frequently preferred by users who seek maximal edge retention, although at the expense of somewhat more work for sharpening.

Is there a noticeable difference in performance between the two steels?

While both steels provide comparable performance, some users may perceive small variances depending on their usage habits and preferences. For example, people who use their knives for intensive chopping or batoning may appreciate CPM154’s somewhat higher toughness.


Both S30V and CPM154 are high-quality knife steels with unique benefits. When deciding between the s30v vs. cpm154, examine your needs, tastes, and budget to make the best choice for your next knife purchase. Whether you value edge retention, ease of sharpening, or overall longevity, both steels provide exceptional performance that will please even the most demanding knife fans.
