I use an old traditional cut throat razor. It cost me $60 at an antique store. $30 for the leather strop, and $40 for the sharpening stone. ($130 investment 8 years ago.)
That works out at $16.25 a year. Even less if I take into account I use the stone and strop to sharpen our kitchen, fishing,pocket, and hunting knives.
The best thing is it doesn’t get clogged up when doing arms, legs and chest areas. (A simple wipe of the blade with a face cloth, and away you go )
