Chef Knife Specs Explained: Length, Stamped vs Forged, Steel, Edge and Care

A chef’s knife listing usually packs in a handful of terms: a blade length, “forged” or “stamped,” a steel name, sometimes a hardness number or an edge angle, a handle material and a care line. Some of these tell you a lot about how the knife will feel in your hand; others are marketing shorthand. This explainer goes through each one, using the Victorinox Fibrox Pro Chef’s Knife, 8 Inch as the worked example.

How we wrote this: specs come from the Victorinox product page for the Fibrox Chef’s Knife Extra Wide, 8 in (item 5.2063.20), read in October 2026. That is the item sold in the US as the Fibrox Pro 8 inch chef’s knife. Where the page does not state a spec, we say so rather than fill it in. We did not test the knife.

The short answer

For most home cooks, the specs that change daily use are blade length, weight and handle. Forged vs stamped tells you how the blade was made, not whether it is good. Steel names and hardness numbers are only useful when the maker states them, and many do not. Care advice should come from the maker, and hand washing and regular honing keep any edge working longer.

Step 1: Blade length, 8 vs 10 inches

Blade length is measured from the tip to the point where the blade meets the handle. The two common chef’s knife sizes are 8 and 10 inches:

• 8 inch: the usual home size. It handles onions, herbs, carrots and chicken on a standard cutting board, and it is easier to control for smaller hands.
• 10 inch: a longer stroke for big jobs such as melons, cabbages or large batches. It needs a bigger board and more room on the counter.

Listed lengths are often rounded. Victorinox sells our example as an 8 inch knife, but its product page lists the length of blade as 7.9 inches, and the full knife as 13.4 inches long. A difference of a tenth of an inch will not matter in use, but it is worth knowing when you compare two listings side by side.

Width counts too. Victorinox calls this model “Extra Wide” and lists a width of 2.2 inches. A taller blade gives your knuckles more clearance above the board and works as a scoop for moving chopped food.

Step 2: Forged vs stamped

These words describe how the blade was shaped:

• Forged: the blade is shaped from heated steel, often with a thick bolster where the blade meets the handle. Forged knives tend to be heavier.
• Stamped: the blade is cut from a sheet of steel, then ground, hardened and sharpened. Stamped knives tend to be thinner and lighter.

The Victorinox page lists “Forged: No,” so this is a stamped knife, and it lists a weight of 6.4 ounces. Neither method is better in itself. Weight and balance are a matter of preference: some cooks like a heavier knife that falls through food, others prefer a light one that is easy to control over a long prep session. If you can, hold a knife before you buy.

Step 3: Steel type and hardness wording

Steel names on knife listings fall into a few groups:

• Stainless steel: contains enough chromium to resist rust and staining.
• High carbon stainless: stainless steel with more carbon, which lets the blade be hardened more. It is a common phrase, and makers use it without one fixed definition.
• Carbon steel: not stainless. It can take a very sharp edge but rusts and discolors if left wet, so it needs drying and oiling. Our pan materials comparison covers the same trade-off for pans.
• Named grades: some makers give a specific alloy name. That is more precise, but only if you know what the grade means.

Victorinox describes our example’s blade as high carbon stainless steel. The product page does not name a grade.

Hardness is usually stated on the Rockwell C scale, written as HRC or HRc followed by a number. A harder blade holds its edge longer but is more brittle and harder to sharpen; a softer one dulls sooner but is easier to hone back and less likely to chip. The Victorinox page does not list a hardness figure, so we do not give one. When a listing does, compare it only with other figures on the same scale.

Step 4: Edge type and edge angle

Victorinox lists a straight edge for this knife, meaning a plain, smooth edge rather than a serrated one. A straight edge is the norm for chef’s knives: it slices cleanly and can be honed and sharpened at home.

Edge angle is the angle at which the edge is ground. Watch the wording: some makers give the angle per side, others give the total of both sides, sometimes called the inclusive angle. A knife sharpened at 15 degrees per side has a 30 degree inclusive angle by simple arithmetic, so the two numbers can describe the same edge. A smaller angle cuts more easily; a larger one is sturdier. The Victorinox page does not state an edge angle. If you sharpen at home, use the angle your sharpener is set for, or ask the maker.

Step 5: The handle

Victorinox lists the handle material as thermoplastic elastomers (TPE), sold under its Fibrox name, and calls the handle ergonomic and non-slip. Other common handle materials are wood, which needs hand washing and occasional oiling, and composite or plastic, which is easier to keep clean. A textured synthetic handle like this one keeps its grip when wet, which suits long prep sessions. As with weight, the best handle is one that fits your hand.

Step 6: Care and sharpening

Victorinox lists this knife as dishwasher safe and covers it with its lifetime warranty. Being dishwasher safe means the handle and blade are built to survive the dishwasher, not that it is the best place for the edge. Hand washing and drying straight after use keeps the edge away from other utensils and spray arms, and many cooks wash every knife by hand for that reason.

Two habits keep any chef’s knife working:

• Hone often: a honing rod realigns the edge between sharpenings.
• Sharpen when honing stops helping: use a whetstone, a pull-through sharpener or a sharpening service, at the angle the maker recommends.

Store the knife in a block, a sheath or on a magnetic strip so the edge does not knock against other tools, and cut on wood or plastic boards rather than glass or stone.

A quick checklist

1. Pick 8 inches for everyday home prep, 10 inches for large jobs.
2. Check the listed weight, and hold the knife if you can.
3. Read “forged” and “stamped” as methods, not grades.
4. Trust steel grades and hardness numbers only when the maker states them.
5. Check whether an edge angle is per side or inclusive.
6. Follow the maker’s care line, and hone between sharpenings.

FAQ

Is a forged knife better than a stamped knife?

Not in itself. Forged knives tend to be heavier and stamped knives lighter. Choose by feel and balance.

Why does an 8 inch knife list 7.9 inches?

Listings round. Victorinox sells our example as 8 inch and gives the measured blade length as 7.9 inches.

What does HRC mean?

It is the Rockwell C hardness scale. Higher numbers mean a harder blade. Not every maker lists it; Victorinox does not for this knife.

Can I put a chef’s knife in the dishwasher?

Only if the maker says so, as Victorinox does for this model. Hand washing still keeps the edge away from other items.
