Re: S30v vs s110vIf both steels have upper range hardness and geometry alike, S110V should have higher strength, wear, edge holding but lower impact toughness then S30V. Edge stability is greater in lower carbide steels as long as the hardness is in the upper range.
S30V will be easier to sharpen in general, but S90V will hold an edge for longer while not being that much harder to sharpen. That also depends on who you get the knife from, heat treament etc. Given a choice between the 2 steels everything else being the same I would choose S90V.
For EDC knives in the $35 and under bracket 8Cr13MoV is really tough steel to beat. 440C is a high-chromium stainless steel with a terrific balance of good toughness and corrosion resistance. 440C takes a nice edge and is fairly easy to resharpen.
High quality Damascus steel is not the strongest metal you can get. Damascus also tends to stay sharper for longer, which is a definite advantage for slicing and dicing. Remember, too, that there are different kinds of Damascus. Carbon Damascus is softer to work with but once hardened, it's harder than stainless.
O1, A2, and D2 are all common carbon steels used in knife-making. Carbon steel uses a complex mixture of carbon, manganese, molybdenum, chromium, nickel, vanadium, and tungsten. More expensive than stainless steel, carbon steel makes superior knife blades for all-around function and strength.
A strong and durable high-quality drop-point pocket knife, the Benchmade Griptilian has a razor-sharp, solid plain-edge 3.45-inch blade which is made from tough American-made stainless steel, and the blade has well-rounded characteristics, a good edge retention and width, and a high corrosion resistance.
- Bohler Uddeholm M390. Bohler M390 is widely revered as being the best all-around knife steel, which has led top companies to widely utilize it in higher end knives.

a higher grade of cutlery steel, with more carbon in it, which allows for much better edge retention when the steel is heat treated properly. It can be hardened to Rockwell 58 hardness, making it one of the hardest stainless steels. Also known as "razor blade steel".
420 has more carbon than 410, but less than 440. As such, it is softer than 440, but has a higher toughness.
420 stainless steel is a martensitic higher carbon version of types 410 and 416 stainless that can be hardened by heat treatment. It has good ductility in the annealed condition but is capable of being hardened up to 50 RHC.
7cr17mov Wear Resistance: it's good for wear resistance, with more than 0.5% of carbon, it has a great wear resistance for low-end steel. 7cr17mov Toughness: not a great toughness, being low-end steel with good hardness and high corrosion resistance, results in a low toughness, but it's a decent one.
Type 440 Stainless Steel, as known as “razor blade steel,” is a hardenable high-carbon chromium steel. When put under heat treatment it attains the highest hardness levels of any grade of stainless steel.
AUS8 will take a better edge but won't hold it as well. D2 will take longer to sharpen but hold it longer. D2 will rust easier.
Knives of this hardness are usually easy to sharpen. 56-58 HRC: Hardness applied for professional German kitchen knives. Knives of this hardness remain sharp long enough for kitchen use, can be sharpened on a sharpening steel and are reasonably easy to sharpen.
440A is used in many production knives because of its edge retention, ease of resharpening, and corrosion resistance. Stronger than the 440A group of stainless steels as a result of higher carbon content, 440C is a high-chromium stainless that has excellent hardness properties.
What is 3cr13 stainless steel? It's a Low-end Chinese Martensitic stainless steel, used today in the knife industry, it has high corrosion resistance and wear resistance, it's known to be a “good for the price” stainless steel.
What is 316 Stainless Steel and Where Is It Used? When it comes to 316 stainless steel, you can expect better corrosion and pitting resistance to chlorides than 304 stainless steel and higher levels of strength at elevated temperatures. This is due in part to the addition of molybdenum.
Stainless steel 304 cannot be hardened by heat treatment. Solution treatment or annealing can be done by rapid cooling after heating to 1010-1120°C.
Both steels are durable and provide excellent resistance to corrosion and rust. 304 stainless steel is the most versatile and widely used austenitic stainless steel in the world, due to its corrosion resistance. If your application uses milder acids or does not contain salt exposure, stainless 304 is perfect.
The Top 10 Strongest Metals

| #1 | Tungsten | 3422°C / 6192 °F |
| #2 | Steel | 1371°C / 2500°F |
| #3 | Chromium | 1907°C / 3465°F, |
| #4 | Titanium | 1668°C / 3032°F |
So just to summarise, 1084 and 1075 are great steels for beginners because they can be done with very rudimentary equipment. It's because the temperature to heat treat it isn't terribly high, 815 to 830 degrees.
Known for its corrosion and heat resistance, stainless steel is overall quality choice of material for forging. By forging stainless steel, virtually any grade of stainless steel, the process enhances and amplifies the existing qualities of stainless steel.
Use a sponge or dishcloth to clean the blade on both sides and wipe away from you so you're never wiping in a way that could cut you. You can also lay the knife flat on the countertop and wipe each side individually if you're worried about cutting yourself.
440C Steel: This steel has a carbon content range between . 95% to 1.20% and is generally considered a higher-end steel. It's extremely common in knives because it provides a good mixture of hardness and corrosion resistance, but also isn't terribly expensive.
The simple answer is 304 contains 18% chromium and 8% nickel while 316 contains 16% chromium, 10% nickel and 2% molybdenum. The molybdenum is added to help resist corrosion to chlorides (like sea water and de-icing salts).
To harden the steel it needs to be cooled to 600 C within 1-2 minutes. One easy way to do so is by quenching in oil. Canola oil is an easy alternative, heat the oil to 30-40 C, colder oil is thicker and will not cool as effectively. At least a couple of liters of oil to help remove the heat quickly enough.
Like other steel forgings, 316 stainless steel forgings can be machined with a series of operations: drilling, boring, turning, ect. To save cost, it is better to control the tolerance that workable in forging. 316 stainless steel has more carbon in it than 316L.
Old files stamped “made in USA” are usually high quality, harden-able steel good for re-purposing into blades. The answer is “maybe.” If you pick up a really old rasp - say pre-WWII - it will likely be high carbon steel all the way through and will probably yield a good blade after you've hardened and tempered it.
Lawn mower blades are low carbon high alloy steel that has high impact resistance and toughness. Hardness is a bad thing in a mower blade, so they don't make the steel hardenable to more than the mid 40's.
There are several different types of stainless steels. Due to this difference, ferritic stainless steels are generally magnetic while austenitic stainless steels usually are not. A ferritic stainless steel owes its magnetism to two factors: its high concentration of iron and its fundamental structure.
To examine a piece of steel, obtain a hand file and file an edge of the selected metal. If the piece of steel has not undergone the hardening process, the metal file should easily 'bite' into the sample. If the metal has been hardened, the file fails to cut into the sample and glances off with little visible effect.
It has plenty of carbon to harden well and make a great blade. Leaf springs and coil springs are my two favorite free steels to repurpose and use for making knives with. Typically 5160 steel, good carbon content, make excellent blades as long as you work it properly
