I would like to use a cut-throat but I view the ones with disposable blades as a bit of a cheat and can't be doing with stropping and occasionally having to resharpen a proper cut-throat.
Never did like the expense of the 3-5 blade cartridge systems either.
I've chosen the middle road and am using an old fashioned Japanese "Feather" brand safety razer with Feather brand safety blades.
I have shaved with my knives though
