5Cr15MoV Steel.

A rung on the budget ladder, made by many mills

5Cr15MoV is a generic Chinese mill grade made to the GB standard, and no single company owns the recipe. What the grade is for is price: it lets a maker put a stainless blade on a knife that has to land well under the cost of a mid-tier alloy.

The published record places it on a clear ladder. 5Cr15MoV is a common step between 3Cr13, the grade below it, and 8Cr13MoV, the widespread entry-tier grade above it. Reading it that way is more useful than reading it alone. It is not trying to compete with the steels higher up the Steel Lab. It is trying to be a meaningful upgrade over the grade below it while keeping the knife cheap.

What 52 to 56 HRC asks of you

The 5Cr15MoV hardness range of 52 to 56 HRC is low for a knife steel, and most of this steel's character follows from it. About 0.50 percent carbon is modest, and carbon is the element a blade's hardness comes from. So the edge is rated fair: it will dull sooner than the harder grades above it under the same cutting.

The other side of a soft steel is that it gives before it breaks. Toughness is rated good, and a softer edge that meets a staple or a knot in wood is more likely to bend over than to chip. A rolled edge can usually be pushed back into line on a honing rod or a strop, and softer steel generally takes less effort to bring back on a stone. For a knife that gets used hard and sharpened by feel, that is a forgiving combination.

Read the range as a description of the alloy, not of the blade in your hand. Knives Now does not test the heat treat of individual knives, and each maker sets where its own blades fall between 52 and 56.

Stepping up to 8Cr13MoV or across to 7Cr17MoV

The obvious next step up from 5Cr15MoV is 8Cr13MoV. It carries more carbon than 5Cr15MoV and is usually shipped harder, and its record rates edge holding fair to good against fair for 5Cr15MoV. That is the upgrade you would be paying for: a longer interval between sharpenings.

The trade runs the other way on rust. The 5Cr15MoV record rates corrosion resistance very good, while the 8Cr13MoV record rates it good, which lines up with the higher chromium in 5Cr15MoV. If the knife lives around water and edge life is not the main complaint, stepping up is not always the right move.

A sideways option is 7Cr17MoV, which carries more carbon and more chromium than 5Cr15MoV, and both are rated very good against corrosion. The grade below 5Cr15MoV, 3Cr13, appears in the record only as the step this steel sits above.

Wet work is where 5Cr15MoV makes the most sense

Chromium is the element that keeps a stainless blade from rusting, and 5Cr15MoV carries about 15 percent of it. The published record credits this grade with more chromium than its close relative 5Cr13MoV, and rates its corrosion resistance very good. For a budget knife, rust resistance is the property this alloy leads with.

That points at wet work. Fishing, cleaning a catch, rinsing a blade in a creek or a sink, and carrying in humid weather are all jobs where a cheap blade that stays clean is worth more than one that holds an edge a little longer and then spots. Both Gerber Ceviche fillet knives on this shelf list a Salt Rx finish on the blade for added corrosion resistance in their descriptions, a finish on top of a steel already rated very good against rust.

Very good is still not rustproof. Rinse off salt water and fish, dry the blade before it goes into a sheath, and a 5Cr15MoV knife asks for very little care beyond that.

Seven listings, six of them Gerber

Seven live listings carry 5Cr15MoV here, covering 6 distinct models, so one listing is a second version of a model already on the shelf. Gerber accounts for 6 and Kershaw for 1. The cheapest listing is $11.99, the most expensive is $37.26, and the median is $17.99. By category, 4 sit in knives, 2 in closeouts and 1 in gear and outdoors. None of the seven is made in the USA, and every model named here is made in China.

The shelf covers more jobs than its size suggests. The Gerber Ceviche Fillet Fixed Blade 7in at $11.99 and its 9 inch sibling at $14.99 are the fishing end, both with green polypropylene handles and plastic sheaths. The Gerber Freeman Guide at $17.99 is a fixed blade with a 4 inch drop point and a nylon belt sheath, and a folding Freeman Guide is listed at the same price. The Kershaw Korra is a small folder with a 2.75 inch stonewashed blade and a linerlock, and the Gerber Haul Plunge Lock at $19.49 carries a 3 inch titanium coated blade. Fillet knife, belt knife and pocket folder, all on one soft stainless.
