Ok. I checked the rec.knives thread and there seemed to be a concensus there that carbon steel knives add tang to your apple. So, I decided to do a test. I used an Opinel with no patina, a Chicago Cutlery butcher knife with a well-seasoned (26 year) patina, and an SAK pocket pal (stainless). I sliced the apple into thirds with the pocket pal and then peeled each third with a different knife. I used the same knife I peeled the third with to slice and eat it. I carefully sniffed each slice as I ate it and sniffed the blade after each cut.
My results:
I could detect no difference in taste or smell. No metallic tang was found in apples sliced by either carbon steel blade.
This could be due to the following:
1) my taster
-some people have more discerning palates than others
2) differences observed by others are caused by using carbon knives that have not been cleaned of loose surface oxidation
3) the apple I used is lower in acid than others that might cause the tang
4) the process needs to last longer (i.e., slice more apples) to allow the acids to corrode the carbon steel so that the effect can be noticeable
5) it's psychological
6) Insert your favorite reason here________ .

I get some pleasure from finding a relentlessly peaceful use for a combative looking knife.
