Juast wondering if anyone knows the rc scale of the basic series blades? Also I have read that busse blades are meant to deform before they chip out,does this make the blade softer and easier to dull faster?and could someone please tell me xactly what is infi,largely carbon or largely stainless.Thanks.

Marsupial,
Welcome to the Busse forum.
First question - 58-60rc
As for the rolled edge vs. chipping question, no, it does not mean that the steel is less hard, but less brittle. Busse knives have a well earned reputation for maintaining their edge. Want proof? Check out the results of the performace tests shown on the Busse website - here.
There's a volume of information here written on each of the questions you've asked. The search feature will allow you to find it pretty easily.
Hope this helps

Yes and no. If the RC was raised it is quite likely that there would be an increase in strength and wear resistance (depending on the grain refinement, carbide dispersion and a few other factors) and of course a small increase in compression resistance (which is what hardness measures). However it is very likely that these gains would be small as compared to the corrosponding drop in impact toughness and ductility.
How would this effect edge retention? Well it depends on what you are cutting, what method you are using, and how much force you are applying. Very generally, the lower the stress the edge is under, the more important strength and wear resistance. The higher the stress the edge is under the more important the impact toughness and ductility.
In regards to compression resistance and edge holding, if the load is applied very slowly then a very high compression resistance is good (cut a bolt in a vise). If the load is applied very quickly (beat the knife through the same bolt with a big mallet), then the critical property will be toughness as the edge will have to be able to resist fracture over indendation.
The Busse Combat blades tend to get used very hard, for obvious reasons. Optomizing them for low stress cutting by pumping up the RC would not result in a blade that performed well in the promoted applications (really heavy use) as they would chip much easier, break under much lower impacts and snap under much lower flex.
There is not enough Cr to make it stainless, but it does not tend to rust easily or extensively.
There are lots of threads dealing with the above questions in more detail in this forum. A search would turn them up.
