I think that the 300SN is really ugly. I feel that they did a really bad job at the patterning on the G10, they should have left the axis lock out, and they should have made the knife longer.
I really like Spyderco's flipper, I really like the ZT 0561, but I hate the 300SN. I think it is a flop for Benchmade, and probably just going to be a "one year wonder." I was really looking forward to Benchmade releasing their flipper, but I was really disappointed when I saw it revealed. I wish that they would made a framelock flipper or at least "un-squished" the knife a little bit. The 300 just looks like someone took a nice knife, and then squished it length-wise. Then to top it all off, they added those cheesy marks on the G10.
The 300SN is a knife I will never buy. I think Benchmade hit their prime about 3-4 years ago when they came out with the 760BK, 630, 635, 610, 615, 806...
