I collect fountain pens and pencils, and I know a lot of people like myself that have an affinity for antique writing instruments also are into straight razors, etc. but I've never tried them myself. I have no issues with using a standard Gillette Fusion or something similar as my facial hair is somewhat weird. An electric razor will not work with how soft/fine my facial hair is. I wouldn't mind trying a straight razor someday, but knowing my luck I'd probably cut myself on accident.
The problem I have with razors like the Fusion is the outrageous cost of the replacement cartridges...sorry, but I'm not paying $5 or more per cart, and certainly not when I can buy 100 DE blades for $15, or 10 Trac II carts for $3-$5 and get as good of a shave, or better...
