There is no quEstion that the GB is, and should, be your decision for a single EDC knife. Personally, I carry the Y2 everywhere I go anlongwith my Amnumzaan or Sebenza. The Y2 is a fighting knife, pure and simple. It compliments my handgun and is clipped to my right pocket or is carried loose in my right jacket pocket or vest pocket so I might deploy it quickly if the need ever arises in a confined space. At three feet, I would rather have a Y2 in my hand than any type of firearm. I pray the need never comes up where I have to defend myself with either a knife or a handgun...
So, yes, by all means get the GB and enjoy a nice EDC. Not my personal favorite as I find it a bit difficult to operate with even light gloves -- the blade release is quite shallow and needs some repetitions to where it is easier to release. Quality and fit & finish -- superb; a top shelf knife made with excellent materials. I have yet to carry it as an EDC, and might consider selling or trading it somewhere down the line......cya
