For me whether a carbon or a stainless takes longer to hone depends more on the amount of honing the little beasty needs. Kind of hard to remember really but I have had carbons that took longer but they just might have needed more work. Those new Thiers Issards always take longer for me. Friodurs like others have said feel pretty normal in the duration on the hones to get done. A lot of variables I guess are baked into the experience. Only the T.I's and probably heavy grinds stand out as taking noticeably longer.:shrug:
