I have to admit am not a big tang fan. However, I do have one an half black tang. OK it was cheap and I liked it. It's also supposed to be one of the smallest tangs. I have had it nearly 3 weeks now.
This is it in the LFS. Prior to purchase.
I will say mine is "special" he insists on cleaning out all the sand under a rock on the left down to the bare bottom of the glass to make his home neat. If I feel like he's being a jerk ill push a bunch of sand under there and then laugh as he cleans it all back out.
