However, these steels have relatively low toughness from the relatively coarse microstructure that results from a large percentage of chromium carbides. These included steels like S60V, Elmax, and M390. Orange dots are PM non-stainless, blue dots are PMstainlessĮarly powder metallurgy stainless steels used high chromium content (17-20%) for corrosion resistance in combination with vanadium for wear resistance.

However, spending all this time on writing about different knife steels eventually led to a series of epiphanies about possibilities in steel design that have not yet been explored. I had considered attempting to come up with my own unique steel compositions, but just wanting to do so doesn’t mean that you have something unique to offer.
It’s sort of like the difference between offering commentary on a football game and actually playing in one. However, this doesn’t necessarily qualify one to design a new steel. As part of this I write articles about the history of different steels including how they were developed and what gives them their properties in terms of composition and processing. It is a fun job but because of my original passion for knife steels I began writing for this website and doing research on the properties of various steels. I was hooked.Īfter ~10 years and 2 kids later I was working at United States Steel developing automotive sheet steels.
I talked to Crucible metallurgists at every knife show I attended and even called them up frequently with many questions and they always did their best to answer. S30V was touted as a steel developed specifically for knives, and I was curious about what that meant exactly what properties were they trying to balance for a knife steel as opposed to tool and die, or high speed steel, injection molding steel, etc.

Not necessarily as something I would do myself, but development of new products, knowledge of the metallurgy required to do so, the trial and error necessary to find an optimal balance, etc.
As I began to be interested in knives and steel in my teens the idea of developing a new steel was very interesting to me. S30V was developed by Crucible and released at the end of 2001. After a time, you’ll be able to find this without a paper or other aid.Thanks to Saptak Dutta, Bill Clancy, Cap Hayes, Electro_Static, Coll Gomila, Kody Ekstrom, Nico, Tom Ewing, Ken Johnson, Brent Stark, Jesse Warren, Malachi Chou-Green, Luke Haag, Bill Harrison, John Geelhoed, and Julian Hamilton for becoming Knife Steel Nerds Patreon supporters! If you take a piece of paper, the corners are at a 90-degree angle.įolding it into thirds gives you 30 degrees, then folding it in half again gives you 15 degrees, which is your angle. Most knives are sharpened at a 15-degree angle, which can be difficult to find. Be very careful at this step because too hard a stroke or too many can remove more steel than you want. This is done by holding the knife perpendicular to the stone and drawing it gently across. The first thing is to remove the damaged steel of the edge, leaving you with fresh, strong steel to work with. If you’ve bought a knife with a good quality, properly treated steel, this shouldn’t be too much. Their depth determines how much steel will have to be removed. Look for breaks, curls, and chips in the edge. Check the DamageĮxamine the blade from each side, and head on to see what kind of damage has been done. As a side note, there are a number of ways to sharpen a knife, this just so happens to be our preference. If you’re a first-timer, we do recommend using something other than your prized possession to practice on.

You can send it back to the maker, but some folks like to know how to sharpen their own knife.
The problem then arises that not everyone knows how to get that razor sharp pocket knife feel back. Every knife today comes sharp from the box, but even with the best steel, the edge will dull eventually.
