But why? You have the Knighthawk in hand and it’s what you described as wanting when you were going to replace it.
The Knighthawk is coated with a durable coating, it’s ok stainless, it’s 6-1/2” so it can do a little chopping, and it has a look you like. Unless you want to start a collection if 6-1/2 knives, or there is something you really don’t like about the Knighthawk you already have, you may want to consider a substantially different knife in size or style as a second knife.
If you haven’t already checked them out, take a moment to phone “We-Be-Knives” on Pier 39 in the City. At one time they sold both Fallkniven and Rat, it’s possible they may have some still around you could take a look at.
As someone mentioned, any knife including the hardest coated Busse is going to get scratched and scuffed if you are using it. You’ll just drive yourself nuts if you want to keep one in “like new” condition and still use the knife.
If a picture is worth 1000 words here’s my 8000+ word essay.
When I read your post I stuck an unused 1095 Old Hickory knife into a cup of tap water and let it sit 14 hours.
Before:
After:
The knife was resting against the rim of the cup so the solid rust accumulated on the upside surface, this shows the other side bottom surface
Here I have wiped the surface with a paper towel. I gave it a polish with steel wool and Flitz except for two inches near the makers mark. Although the photos don’t show it very well you have unstained steel on the left, the remaining stain from wiping off the surface rust and then untouched original surface on the right. If the full blade had been polished five minutes there would be no stain remaining.
The steel started to show changes after 3 or 4 hours in the water so rust issues with 1095 seem to be with the storage of the steel. Dried and given a coat of mineral oil before long term storage and there shouldn't be any problem. In use and with an occasional wipe and rust will not take hold. Cut some fruit and vegetables and 1095 will show stain from the acid. Of course all of that is minimized with a coated blade.
I'm thinking that since you already have an adequate 6-1/2 knife and like the look of the RC-6 maybe spend a bit less, expand your options, and consider something like the RC-4 or even RC-3.
