These ratings don't seem too different from Larrin's data.
Here is my personal and subjective view
- the entire "data-view" on steels is heavily distorted by box and rope cutting comparisons, which don't have much relevance to what I do day-2-day. I have a dedicated box cutter, and there is that. In the foreseeable future, the box and rope cutting emphasis on youtube and internet fora is unlikely to change.
- Box and Rope cutting is also important for cutting competitions, where the best compromise between cutting and chopping is achieved today by 4V and M4. In the future you might add Magnacut to these "competition steels"
- 4V is actually not that tough - I've broken a 4V knife tip (on a Manix 2) and much prefer tougher steels like 3V, AEB-L, etc.
- When many people read "tough" they think of a knife catastrophically breaking. However, the toughness indices in your post, and in Larrin's data also mean that a knife wont chip.
higher toughness = higher edge stability.
- The biggest differentiation of Magnacut to other steels in my eyes is extremely high corrosion resistance. Similar to LC200N (more corrosion resistant than AEB-L) but harder.
When I look at my hard Japanese kitchen knives, after usage they show chips. Due to high edge stability, AEB-L wears more smoothly, it's much easier to go over a stone a couple of times when the knife is needed ... think razor blades: that's what AEB-L was made for.
IMO, AEB-L is one of the best kitchen knife steels out there, likely also better than Magnacut. Unless you need super corrosion resistance, say for a lime cutter, and you don't clean your knives very often ....
My 2 cents,
Roland.
