I want to buy from straight razor designs because there is an affordable set that comes with a strop, however the return policy isnt to my liking.. it cannot be returned if used. I'm afraid my dad will need to use it before deciding if it is the right one for him or not. I found some on amazon.com.. they are Dovo, but will they come honed/sharpened? (I am planning on getting him a strop anyway but I don't know if he's ever even used one haha). What's the difference between half hallow and full hallow.. is one better than the other?

Thanks for all the help btw... I will definately be pointing my dad in this direction after he recieves his razor!
