When it comes to pocket knives, the quality of steel used can make a huge difference in their effectiveness and performance.

Two of the most popular stainless steel choices for pocket knives are CPM S30V steel and 154CM steel.

These two sheets of steel have become well-known among pocket knife enthusiasts due to their superior cutting-edge retention, wear resistance, corrosion resistance, and overall strength.

In this article, we’ll take an in-depth look at both materials to determine which one is best suited for pocket knife applications.

We’ll compare their properties such as hardness ratings, toughness levels, machinability rates, and more so you can decide which one is right for your pocket knife needs.

 

CPM S30V Steel

CPM S30V steel is martensitic stainless steel with high levels of carbon and vanadium, making it one of the most popular choices for pocket knives.

It was initially developed as a blade steel in 2001 by Crucible Industries and features superior edge-holding capability, corrosion resistance, and strength.

It has a hardness rating of 58-60 HRC, making it a relatively hard steel that can take a sharp edge.

It also has excellent toughness and wears resistance so pocket knife blades made with this steel are sure to last for years.

 

Benefits of CPM S30V Steel

1. Excellent edge-holding capability

When searching for the perfect pocket knife, look no further than CPM S30V steel.

Its renowned edge retention, corrosion resistance, and exceptional strength make it a top choice among manufacturers and users alike.

It has a hardness rating of 58-60 HRC which makes it a relatively hard steel that can take a sharp edge.

Additionally, this steel also has excellent toughness and wear resistance so pocket knife blades made with this material are sure to have a long-lasting performance.

The combination of these features makes CPM S30V steel an ideal choice for pocket knives as it offers superior cutting abilities without sacrificing durability or longevity.

The edge-holding capability of CPM S30V steel is especially noteworthy; pocket knives made with this steel are sure to stay sharp for a long time.

2. Corrosion and wear resistance

CPM S30V steel is one of the most corrosion and wear-resistant pocket knife steels available.

Its high carbon content provides it with remarkable strength, while its high vanadium content strengthens the steel’s ability to stand up against wear.

This steel also has chromium which contributes to its overall corrosion resistance. The addition of these elements provides pocket knives made with CPM S30V steel with superior protection against corrosion and wear.

Users can rest assured that pocket knives made using this steel will remain in good condition for many years, even if they are used frequently.

3. Hardness rating of 58-60 HRC

CPM S30V steel has a hardness rating of 58-60 HRC, making it one of the hardest pocket knife steels available.

This steel is capable of taking and maintaining an incredibly sharp edge so pocket knives made with this material are sure to stay sharp for much longer than other pocket knife steels.

Additionally, pocket knives made with CPM S30V steel are incredibly resistant to wear and tear, making them some of the most durable pocket knives available.

4. Can take a sharp edge

The hardness rating of CPM S30V steel also contributes to its ability to take and maintain a sharp edge.

Pocket knives made with this steel have a greater resistance to dulling even after frequent use, giving pocket knife users the confidence that their pocket knives will remain sharp for a long time.

The sharp edge also makes pocket knives made with this steel more effective at cutting and slicing than other pocket knife steels.

5. Highly resistant to chipping or breaking

The superior strength and toughness of CPM S30V steel make pocket knives made with this material highly resistant to chipping or breaking.

The pocket knife blades made with this steel can withstand a greater amount of stress, giving pocket knife users the peace of mind that their pocket knives won’t break even with frequent use.

 

154 CM Steel

154 CM steel is one of the most popular pocket knife steels and is favored by many pocket knife manufacturers for its excellent properties.

It has a good strength-to-weight ratio, excellent corrosion resistance, and outstanding edge retention.

It is also one of the most durable pocket knife steels available due to its high chromium content and its ability to maintain an effective balance between toughness and wear resistance.

As a result, pocket knives made with 154 CM steel are well known for their long-lasting performance and reliability.

However, this steel is more expensive than other pocket knives stainless steel and tends to be slightly harder to sharpen.

Nevertheless, the 154 CM steel is continuously the favorite of many knife enthusiasts and pocket knife users for its excellent properties which make pocket knives made with this steel last longer and perform better.

Benefits of 154 CM Steel

1. Strength-to-weight ratio

154 CM steel has an excellent strength-to-weight ratio, meaning pocket knives made with this material are lightweight yet very strong.

This makes pocket knives made with this steel ideal for everyday carry as they are easy to handle and can withstand a considerable amount of stress without breaking.

2. Excellent corrosion resistance

Pocket knives made with 154 CM steel have excellent corrosion resistance due to their high chromium content.

Users can be assured that their pocket knives will stay in working condition for years to come, no matter how often they are used.

Compared to CPM S30V, 154 CM steel has slightly less corrosion resistance, but it is still more than enough for pocket knives.

3. Ease of sharpening

154 CM steel is relatively easy to sharpen, making pocket knives made with this material ideal for outdoorsmen who spend a lot of time in the wilderness and need to keep their pocket knives sharp.

The steel’s composition allows pocket knives to be sharpened with relative ease, while still providing the necessary strength and durability that pocket knives need.

In comparison, CPM S30V is more difficult to sharpen but provides superior edge retention when compared to 154 CM steel.

4. Cost-effectiveness

Pocket knives made with 154 CM steel are generally more cost-effective than pocket knives made with CPM S30V.

This is because the composition of 154 CM steel requires fewer resources and is easier to produce, making pocket knives produced from this steel less expensive to purchase.

5. Durability

Pocket knives made with 154 CM steel are renowned for their durability and long-lasting performance.

This is due to the steel’s high chromium content, which provides pocket knives with excellent wear resistance while still maintaining a good balance between strength and toughness.

Have several of both. 154CM is easier to make ridiculously sharp, but is easier to damage if you cut something tough or hard, and after the edge starts to go it will keep getting duller and duller till you resharpen. S30V is more resistant to damage, and can usually be steeled or stropped to bring the edge back a little better than 154CM. It will loose it's "razor" edge about as quick as 154CM, but then it settles into a sharp and useable, but not hair splitting edge that lasts a LONG time. People say it's tough to sharpen, especially compared to 154CM, but if you use silicon carbide or diamond stones, or use a power sharpener, it isn't much different till you get into fine grits. Heat treating and hardness also vary, as do edge geometry and angle. I have some knives that may be in the same steel, but seem to take a much better edge, or last a lot longer than another knife in the same steel.

It takes noticeably longer to polish and strop S30V to finish it, gets worse the more Vanadium a blade has. Where my S30V takes maybe 25% longer to sharpen, twice as long to polish/strop compared to 154CM, my S110V manix2 takes about 2-3 times longer to sharpen and 5-10 times longer to polish/strop compared to the same knife in S30V. In S30V's case the little bit of extra work is well worth the better edge holding, and spending a long time to polish it up and eek out the sharpest edge usually isn't worth it compared to sharpening to a decent edge, then just stropping enough to clean the edge up. S35VN and Elmax are getting more popular, and both are a step up from S30V, noticeably tougher and more resistant to damage, they also take a finer edge, hold a razor-edge longer, and are actually easier to sharpen.
