I'm looking at straight razors for my brother(christmas gift). He works in construction, likes collecting knives and has burly facial hair. He's been using one with replaceable blades. I'm considering Dovo best quality 5/8". I figure it's nicer than what he's currently using and, if he loses it, I'll still be able to forgive him.

So the question is full or half hollow? I've read that half hollows hold their sharpness longer which might be better considering his thick, burly facial hair. What advice can you lend me?

All this research has also caused me to consider switching to a DE myself. Since I'm female, I'll be posting in the ladies forum shortly.
