I have the ATS-34 model and the plain edge 420hc model. The bad thing was that on the ats model they only had plastic handles, with no metal spine, and only a liner on one side. I think they have changed that now. The 420hc model I have has a much better handle, with full metal spine and two metal liners. The action was very stiff the first few days, but now it has become my smoothest knife, since I open and close it about 50 times a day. The pocket clip is alright, since it screws into brass nuts recessed into the plastic handles. But it can wobble from side to side once the screws loosen up just a bit. The thermoplastic handle material itself is quite strong, and I have dropped the knife onto the floor a few times with no cracking. I also fell on the knife when it was in my side pocket, and the handles were still fine. The blade is very pointy, and I it is good for stabbing stuff, but the hollow grind is too short on the width of the blade in my opinion. They should have ground it higher. Both knives pass the spine whack test. I really like to slam them on any solid object I'm around, just to see if they will ever colapse, but so far they haven't. But I warn you in advance that you shouldn't stab anything with this knife in the saber grip even if the blade passes the whack test. The liner protrudes enough so that just squeezing the knife hard will disengage the lock. Reverse grip is not a problem though, since the pinky does not close the lock. For 29 dollars the plain edge model is really quite good. I saw a keshaw random task the other day, and I really didn't think it was worth five or six odessey knives. The last thing that I like is the pivot screw is a screw rather than a pin. Side to side blade wobble can be corrected with a few turns.
