i love my flash knives and will order the new versions as soon as they are released(no pun intended

i had the same problem with the opening of my flash knives when i first recieved them. the problem was NOT the knives, but in the technique in which they are opened(ex. thumb following blade and stopping from opening, etc.) what i have found through experimenting with them is...
do NOT try to open the knife like a conventional thumb stud knife(do not push out, flip knife, wrist twist, etc), instead, push the thumb stud "UP", towards the top of the knife and do NOT let your thumb follow. actually, you just want to "bump" it enough to let the spring take over. for some, it might take some practice, but it is WELL worth the time. i like the function better than my switchblades(no, i am not giving them away

i like the "no recoil" feature. my flash I is a lot faster than my flash II, i don't know why though, unless the desigh did not take into consideration the added mass/weight of the larger series, but both work great(although i do like the "speedier" flash I a bit better) i do wish they would come up with a different blade for the knife though(ast-34 or 154-cm would be nice with a design similar to the night vision with plain and serrated options... TiNi too!)
