My Copper Hat silvertip made a very nice lather indeed from my vintage Yardley shaving soap (unavailable for decades). The fragrance is still present, but nearly so strong as that from my vintage Lenthéric shaving soap of the same era.
But the lather did the job, and my iKon 102 had no trouble at all in producing a perfect result in three comfortable passes. A splash of Fine’s l’Orange Noir and I’m ready for a new week, which begins with a dental appointment.
