I was wondering how dose the R2 compare with AS, in ease of resharpening and edge retention?
- Quite different species really. R2 is a powdered stainless, AS is a carbon. R2 is more difficult to sharpen and should hold an edge longer. I've rarely personally tested edge retention enough to say with absolute certainly.....but I've heard/read enough from people who have to feel comfortable with the statement. We're not talking night and day difference though. AS is no slouch in edge retention and R2 isn't a complete bear to sharpen. Also in the AS knives with the stainless steel Clad, how much of the cutting core dose it expose?
- Not much....1/4" maybe....it's a wavy linewith constant sharpening would the blade eventually wear down to the clad?
- Yes and no.....first, under home use this would take many years. Second, even if you do sharpen enough to get into the cladding, the knife isn't ruined. The AS core runs through the blade, so as you sharpen you remove the cladding, exposing the AS core. If you do have the knife that long you will be thinning the knife.....errr, getting technical. This isn't an issue, me doesn't think, you should be concerned with.
Please, let me know if you want the complete technical answer. Dose the patina surviving the grinding of a wet stone?
- The patina is only a surface reaction, so no, it will not survive grinding. You will probably leave part of the patina on the upper exposed core, but the edge where you sharpen will be bright again.
I might recommend a solid carbon knife.....you seem to be somewhat curious about carbon knives:http://www.chefknivestogo.com/misono4.html
Really great knife....carbon isn't that big an issue to take care of.
