A shavette IS a straight razor and while I enjoy my traditional straight razors, I use a shavette quite often. It is hard to beat the results and pure ease of the shave. If I could have only one straight razor for the rest of my life, it would have to be the shavette.Guys in this forum might poo-poo this, but I use a replaceable-blade straight razor for every shave. Some might not think of it as a straight razor, but I do. In any case, it's an open-blade razor.
I choose to use an open-blade razor because I feel like I get the best results for me. Counterintuitively, I find open blades provide the gentlest method of shaving. Plus, I really enjoy it.
