The online community of knife collectors, A Knife Family Forged in Steel
I thought that I would start a discussion about what kind of carbon steels you guys favor.
Tell us what type of steel you prefer and why.
Personally, I am a huge fan of Case's CV. I have heard that it's not as good of carbon steel as what Case formerly used, but I don't think that I'll ever find out either. I think the CV holds a really decent edge though.
My next second would be 1095. I only have one knife that was made with 1095. Its a more tactical-style fixed blade made by ESEE. Don't have enough use on it to know if it's better than CV.

1095 seems to be a favorite to a lot of people.
I am sure that if I purchased and carried a Great Eastern Cutlery knife with the 1095 steel , then my opinions would change. But like I said, I don't have a whole lot of experience with it. I did cut up some boxes with my 1095 knife though and it held it's edge really well. I didn't feel as if I needed to sharpen it afterwards.
I am more of a pocket knife guy. But if I could find a decent-looking, hunting-style fixed blade with a stag or wooden handle and a ~3" blade with a nice leather sheath, then I would carry it all of the time. A 1095 blade would make it even better.
Hmm.. White Steel #1 but -only- if properly forged. Assab K120 is quite good too, Bohler 990k is also a clear favorite.
For longer blades I would say Tamahagane at around 1.7% carbon. The "bite" and cutting ability of Tamahagane is simply amazing, the edge almost feels like a magnet to anything that comes close to the edge.
There's also Tougou-Inukubi which is one of the hardest steels today to smith. Purer in iron than White Steel (even K120 which is super-pure with iron) and Tamahagane but not quite as high with the carbon percentage to keep the same performance.
It does have the biting feeling of Tamahagane and Bohler 990k because of it's high iron purity.
Those are a few but I can't really choose since I have a full array of different carbon tools, purer carbon tools, less pure ones. Then alloy tools, purer alloy tools and heavier alloy types so that I'm covered for any need I run up against.
For example, my White steel #1 tempered at 100 degrees is a true treat to use when working wood but it would shatter like glass if swung like a knife. For that I have a WS#2 Japanese woodworking machete (hybrid design to cut down trees aswell as branch and bark them, flat edge).
And so on, I simply switch my steel for my needs. The only finger I can put as a favorite is WS#1 tempered at 100 degrees ;)
I was first exposed to D2 in the steel fab industry. Punches, knives, & other die components are hardened to a 60~61 Rc & then used to shear & punch holes in softer (30~32 Rc) steel. Production runs of 25K ~ 35K pieces between scheduled maintence / sharpenings are common w/o proper lubrication to the die. Proper auto-lube in the die & a good run could be pushed to 55k parts before burrs would force the pulling of the die for sharpening.
This is simply some tuff schtuff !!!
Dale, you really need to forget your machinist past, especially when it comes to carbon steels. The uses are completely different and to be honest, your comment is mislocated since D2 isn't a carbon steel but made primarily for industrial use in the beginning.
Such a steel has it's limits and I could source you to a knife with performance that would literally drop your jaw since you can go from cutting straight into tempered steel without a single lost edge serration. Since you enjoy the machinist steels so much I'm actually surprised that you aren't using BS#1 & 2 more, both superior steels, hardens better, cuts better, finer grain and so on.
I personally use BS#1 as a burnishing steel for removing steel, it eats anything up (D2 is very low in this food chain), taking shavings out of as far as HRC 68 steel.
But please, what I want to get across is, don't limit yourself to D2. There are so many incredible steels out in the world and it's horrible that people are touting D2 as something end-all be-all solution.
I feel terribly out of place here at iKC, I probably won't stick around for too long when it takes me months to convince someone to simply try an imported craft.
