CPM 3V steel fixed knife

What is CPM?

CPM is a type of powder steel. Powder steel, like CPM 3V, is produced by atomizing molten steel into fine powder particles which are pressed together under high pressure and sintered into a solid block. This process leaves you with a finer, more uniform microstructure than traditional forged steel. The result is better sharpness retention, wear resistance and toughness. As such powder steel is popular for use in top-quality knives that retain their sharpness well but are also still relatively easy to sharpen.

How good is CPM 3V steel?

When it comes down to a steel type 'good' is of course relative term. A steel type is as good as it adheres to the demands of the user. So how does that pan out for CPM 3V? CPM 3V is a tough type of steel. As such the risk of chipping or breaks is a lot lower. The alloying elements add to the good wear resistance. This means that the blade will retain its sharpness for a long time.

What are the disadvantages of CPM 3V steel?

With so many steel types out there it can be quite the task to determine which is the best choice for you. That is why it is also important to keep the 'disadvantages' of CPM 3V in mind. CPM is not stainless. This means the surface can rust if not maintained properly. CPM 3V is highly resistant to wear and tear. This also means that CPM 3V is harder to sharpen. To make your life a little easier when it comes to sharpening 3V, we recommend diamond-coated or ceramic sharpening stones.

Which is better? CPM 3V compared to...?

Many types of steel are used to produce fixed knives. But which steel type is better? First and foremost, this depends on what you are looking for. If, however, you do want to make a comparison: CPM 3V can be compared to D2 and CPM CruWear.

D2 steel

D2 is a tool steel with a high chrome and carbon content. It is resistant to wear and tear, but not as tough as CPM 3V.

CPM CruWear

CPM CruWear is a tool steel developed by Crucible Industries. It offers a good balance between toughness and wear resistance. It is also better equipped to handle corrosion than CPM 3V.

CPM 3V fans: which brands use 3V steel?

You have never been more sure: you are looking for a fixed knife with a blade made from CPM 3V steel. But which brand uses this type of steel for their fixed blades and appeals to you most? A good example is Bark River Knives. This brand uses CPM 3V for, amongst others, bushcraft knives and hunting knives.

CPM 3V maintenance

CPM 3V, like any type of steel, needs to maintained to make the most of it. For CPM 3V it is important to properly clean the blade after use. Remove moisture and/or dirt. Anything that can lead to corrosion. Add a thin layer of protective oil to the blade and make sure you store your knife in a dry place. Preferably in a sheath that won't absorb moisture.

A sharp edge ensures that your fixed blade will function as it should. Due to the high wear resistance of CPM 3V it is more difficult to sharpen. But not impossible! Looking for the best results? Use diamond-coated or ceramic sharpening stones.
