All the plusses and minuses for each have been covered pretty much so it comes down to preference. I can appreciate both: from a design perspective, 2 & 3 piece razors are simplicity and form-fit-function at its most basic level, nothing wasted, but from a mechanical perspective, TTOs (and especially adjustables) are just plain cool (as long as kept in good working order). I'll reach for either on any given occasion, but 2/3 piece open combs are great for mowing down longer growth without clogging, and TTOs are great for everyday comfort when growth is less.I got the King Gillette razor for Xmas. I tighten it until it gets resistance and then just a bit more.
I'm wondering what the advantages of a 2- or 3-piece razor over the TTO razors are.
