very cool Dave.just cut the safety guards off of a post war tech razor..cap and blade and leftover blade support..the great equalizer..no other razor required..seriously ..glad you are enjoying the karve experience..
some razors require it.depends on the blade exposure....all good...i find the gillette sweet spot on the edge of the cap..
you know this is a "ride the cap "type of educational thread..ask the forefathers who created the tread. there are a hasndful of razors that don't fit this technique but..the basics are..
The so called safety bar isn't really necessary anyway. Use a fresh feather blade to get the best results. tp
