I really like the shave I get from my Merkur 38HD and was wondering if there is a vintage open comb that would replicate the closeness of the shave I get from my 38HD? I have a Vintage Rotbart open comb I picked up off the BST that I like but even with one shim in it I can not get as close as I can with my 38HD. I'll be trying another shim soon, but are there any other options?
