They didn't work for shit in my Merkur Futur.
Hmmm... I always use Feather blades in my Classic HD and get a real nice, close shave - admittedly 2-pass.
For the OP- a safety razor takes skill to use and I find it more enjoyable and more economical, but realistically I use it to avoid ingrowns, so if you can use a Mach3 - more power to you.
