Chris:
totally agree I am more carefull and use more tension with the full hollows; this is why I said wedges seem easier to handle

Justin:
exactly for the reasons Chris and I discussed - you can vary the tension on a hanging strop. Sometimes, I feel I need less tension to really get the edge. For razors, which approach saber grind there is no other option, really. Bench / paddle simply would not work - period. Plus, it's more conveniend that using a beam
