Beautiful. Everything a knife needs and nothing that it doesn't. I particularly like the continuous curve along the back of the knife - from the point, down the spine, to the end of the handle. Also the thick, slightly colored liners. The handle looks very useable - smooth and well contoured. The blade color is interesting - is it blued, is the steel naturally a bit dark, or is it a quirk of the photo?
Very minor quibbles - I might have extended the cutting edge a bit further towards the handle (though this configuration may make sense when you hold the knife). Also, how does the tab of the locking liner feel when you grip the knife? It looks like a tough compromise between getting poked in the hand and being able to access the liner lock. Finally, it could use a nice, clean "Klein" stamp on the blade - this is definitely one to put your name on!
Thanks for the pics.
