Ultimatum steel

Tue Jun 19, 2012 11:48 pm

I was wondering why you choose 19C27 for the Ultimatum vs AEB-L (you've said this is your favorite stainless) or CMP-154.

Each must make a trade off between ability to take an edge, edge retention, corrosion resistance, etc. What were your design considerations for the Ultimatum?

Good question. I like the Suisin Inox Honiaki a lot and they use 19C27 so I thought it would be interesting to try it.

There are lots of good steels out there and I'm curious about trying different stuff just like you guys. There are also trade offs between different steels. 19C27 holds its edge a little better than 13c26 (aeb-l) but doesn't sharpen quites as easily.

19c27 and aeb-l are alot alike. If you like one you will definitely like the other.

My understanding is that 19C27 is Sandivik's attempt to create a steel with greater wear resistance than 13C26 (AEB-L). AEB-L was created for very high edge stability tasks such as razors also requiring corrosion resistance. If I understand it right 19C27 should have an increased carbide volume over 13C26 (AEB-L) thus provide wear resistance hopefully creating a nice comprise as a steel.

19c27 is a little more stiff, feels a little harder. Tougher feeling steel. Personally I like 19c27 a little better, although AEB-L will get a little sharper.
