Difference from a "Hi" and a "Bo-Hi"?

[tanukimario]

Basically as the title says, is there a difference from a "hi" and a "bo-hi"? Doing a little bit of research, it seems to be the same thing but maybe it's not. So, katana experts out there, is there a difference?

Hi is a groove and Bo-hi is a wide groove.;)

[Brian Brazier]

that is my understanding as well, personally I'm a no Hi of any kinda guy

[tanukimario]

So then... there's no major difference?

Well a HI is more likely to be used for it's beauty(like on a tanto) then any thing else.Where as BO-HI is more likely to be used to hide forging imperfections and lowing the weight of the sword.It does not make the blade stronger !
