Thanks for your reply, the reason for a wedge to me is the lower elasticity you would find in the thinner hollow blades. The more stiffer wedge blade kind of makes sense as you say more heft as well. Sharpness is certainly an issue but the last razor I bought was from Lynn Abrams a Dovo 5/8 Prima silver steel (a new purchase) with a very nice edge on it. I also have an older Boker Edelweiss 5/8 with a good edge on it. Thanks again for your reply, I may try a wedge if only for my own clarity and if I do I will report my findings the this board and again thanks I value the information you gave me.
