@Ferret619 I tape all my spines on almost everything purely to stop wear but this is purely my preference & not essential
my exceptions are.
Kamisori - normally no tape on the Omote (front - beveled side), but tape on the Ura ( back - stamped face) and use about a 10:1 (Omote:Ura) honing ratio
Microtome - same a Kamisori with no tape on the flat side but only if being honed correctly for use as a Microtome, but I use 1 layer of tape if being used as a razor & once the flat side is true I use a similar honing system as the Kamisori
Western ground hollows - 1/4 to full hollows all get 1 layer of tape
Wedges - new or in NOS shape with no or minimal hone wear, I use 1 layer as usual
now the fun starts,
Vintage wedges with heavy wear from decades of stropping on pasted strops take a lot to reset the bevels,
so I start with several layers (3-5+) of tape until I have a set bevel again & corrected edge geometry etc,
also the multiply layers of tape on the spine are usually required to correct spine wear & fill hollows to keep the geometry right by grinding the tape away until you have a neat looking spine again, then apply fresh tape to protect it like a good spine.
from there we have a couple of options depending on how bad the wear is & the desired finish
Option 1 - we can continue grinding away on a 1k or less until we have 1 layer of tape & a large bevel face
I must note grinding a 3mm plus wide face on an old wedge is not fun & time consuming with takes lots of tape changes to keep the angles,
Option 2 - keep the multiple layers of tape & run through to finisher & finish off on a pasted strop to smooth the hollow to bevel transition if required
but I personally feel anything more than 3 layers of tape & the bevel angle is too great & the angle required when shaving feels off (like movie shaves 90° to your face)
Option 3 - like so many a vintage wedge before us, regrind the hollow & reduce the bevel face & start fresh
hope this helps someone
