I only have the gso 4.1. For what it's worth, it's a fine knife. I however keep going back to my becker bk 16. In most ways the 4.1 is the better blade. The steel is better, handle material is better, sheath is nicer (though I feel it needs the extension to ride lower). But for some reason, I still prefer my becker and it sees much more time than the gso outside. I will still carry my 4.1 from time to time and I don't have anything negative to say about it. But for the price point, I would much rather have the becker at 1/3 the cost.
