Truth be told, I had forgotten about the Guardian3 until I saw it go up for sale at BladeHQ the other day, and the memory of this thread came rushing back and I ordered one immediately, because, come on, a fixed blade made of M390 at that price? Done. Deal. Anyway, after some frustration with the post office, I got mine in today, and I'm quite happy with it; looks as sharp as it is. Sheath fits well, comfortable in the hand, and fairly light, with just enough heft to let you know it's there, which I like. Hits all the right buttons for an edc for sure.
If I had one critique, it would be where the choil transitions into the back part of the handle. It's awful pointy, which is fine under normal use, but under hard use can poke into your hand a bit. At least for me, but to be fair my hands are on larger side. That, and it's been digging into the sheath while drawing or re-sheathing and has torn up the interior a little bit (it has come out with some small chunks of leather a couple times) but again, I play with my knives quite a bit, so I've probably been drawing it more than most would in a day, lol.
Be that as it may, I'm still totally gonna carry this one every day. It's too awesome to not.
