I just got the Whisper from 1SKS a few days ago.
I'll just say, that it makes my Benchmade 710 M2HS look dull...
This is, by far, the sexiest knife I've seen, and as with the Whirlwind, the Whisper's assisted open is a gem.
The one thing I will say, is that the locking mechanism for keeping the knife open seems a little suspect. In that, I mean I keep getting the feeling the little spring-tack lock seems a little too exposed, to where I can accidentally have it scrape something, spring it back in, and the knife would collapse on my fingers...
Maybe with use and time, I'll grow to trust that little lock, but for right now, I've used this knife to cut everything from tree limbs to envelope and vegetables, and it's sharp as hell, and performs just as I expect it to...
This is definately one knife that impresses a lot of people I've shown it to. I absolutely love it for the looks, the sharpness, the rigidity of the knife, and the assisted spring open...
