Far and away the best way to strop a blade particularly for fine wood carving in dense wood and obstinate grain is using a set of Micro Mesh pads. I’ve been using these for over 20 years and have yet to wear them out. I cane go all the way to 12,000 grit if necessary and usually start at 3,200 with when the blade is reasonably sharp to start with. These pads can also be used polish up wood before and after finishing. I seldom reach for anything else.
