OK first off guys, does kendrajay have an eye for a good razor or what!
Secondly posting links to razors in any thread is extremely dangerous to the health... of my wallet. :D
As to your razors from an aesthetic point of view the Dovo is gorgeous and from the looks of it its brand spanking new. The Spartacus is also a beaut. These two would be my recommendations because should he decide to take up the hobby they are good quality makes which can be forgiving to the newcomer. I am less convinced about the first TI personally- whilst it would shave just as well as the other the scales (handle) are not to my taste. I guess it comes down to what he would prefer the scales to be made out of. I have no experience of the Bengal razor personally but from the way it looks I think he may prefer something brand new.
If you are uncertain would you consider letting him choose? Perhaps he could browse and tell you the kind of razor he likes. Then you could make a more informed decision based on that.
Either way, keep us informed of what you decide and whether he decides to take up the hobby :tu
