I would go top and bottom but I would ditch the font.
It looks too much like it's trying to be trendy, and I don't want a "trendy" knife--I want one that will last. I honestly have never wanted one of Ban's knives simply because I don't like his logo. I wouldn't feel right about asking him not to put it on the knife, or sanding it off later so I just won't buy one. The quality from all reports is great, but when I can get a knife of the same quality with a less obtrusive logo? I will.
Just my mileage, yours may vary.
