It's the best production fighting folder made today, and probably the best fighting folder period.
It's 5.45" blade length was specifically chosen to allow TX legality.
The rest of what I have to say about it is here:

There's also a ton of older threads in this forum and on the main "General" forum, use the search function. But what you'll find is that the people who buy them as street defense pieces absolutely LOVE 'em..."utility buyers" are sometimes unwilling to pack something quite so huge.
The few times anyone has had a quality issue was in some of the early production pieces and REKAT always took very good care of the customers.
In short, it's the best combat folder made, and it's barely legal for the TX market. If that's what you want, you've found it.
I own (and carry daily) Sifu serial number 1 because I pressured REKAT into building a megafolder
. But other than coming up with the 5.45" blade length for TX legality, it's all REKAT's design and a damn good one. Bob Taylor is a grip ergonomics wizard, he made those fingergrooves WORK far better than they look just from pictures.
