I apoligize for this thread but I didn't see recent similarities. I was curious to know who will take stainless over carbon for steel. Reason I ask is, as ashamed as I am to say, I will. I prefer the more sandvik stainless over carbon, as far as I can tell with my testing, it holds an edge as well as the carbon as far as I know. I'm not that hardcore, I'm not that abusive, but maybe that's the point, as farm as I do my business, it's just as good. Also though, I would personally take a slight loss in the name of no rust. Anyone in a similar camp?
BD,
Sandvik 12C27 is an excellent steel.
Oversimplifying things greatly, you can divide the steels into those that have fine carbides and those that have larger carbides. This is sort of like the difference between cement (fine particles like sand) and concrete (large particles like gravel). Steels with larger carbides have their place and their fans. For cutting abrasive materials like cardboard, carbides resist abrasion wear but they also tend to be a bit harder to sharpen and tend to not take take as fine of an edge as fine carbide steels.
At the same time, good fine carbide steels have their uses and their fans too. They tend to be tough, take a fine edge and are easy to sharpen with traditional stones (or coffee mugs).
The thing with fine carbide steels is that among the fine carbide stainless that is available, there is a very wide range of quality. Some fine carbide stainless, like 420J2 or generic 420 can't be hardened up well so it's soft and prone to rolling edges easily. Others, like 420HC and Sandvik 12C27 can be hardened quite high, which is good. But again, it depends on the knife manufacturer and how they harden and temper the steel. Both Buck and Case use 420HC but Buck's is noticeably harder and nicer because of it IMO. All of this is just as true for carbon steel, which is also a form of fine grained steel. Schrade-Walden and Schrade USA did a great job with carbon steel and currently Becker and GEC have good reputations for getting carbon nice and hard. Opinel's Carbon is a bit soft for my tastes. So again, it depends on the heat treat/tempering.
Given equally good heat treat/tempering, I no longer see any advantage to carbon steel. I say this as a former carbon snob. In particular, Buck's 420HC and the 12C27 as done by Opinel and Mora are every bit as good as the very hard 1095 in my older Schrade-Walden and Schrade USA knives. And when you get that sort of edge performance with the general lack of corrosion, it's an easy decision.
I'll still buy carbon steel. I like it a lot. But given an option between carbon steel and well heat treated/tempered 12C27 or 420HC, I'll choose the stainless.
