Benchmade 940 Osbourne. I payed $175 for mine, but that was 4 years ago, the price has probably went up on them. I used to buy at least one new knife a year, usually around $50 each. I saw this knife on vacation, and had to have it, I ended up spending the money I didn't spend on cigars to smoke on the beach at night on the knife. I haven't bought another knife since. I don't see the need to, it's the perfect knife. Not to big, not too small. It's not spring assisted because it doesn't need to be, it opens faster than one, and closes just as easily with one hand.
At the time I was a little skeptical on spending that kind of money on a knife, mainly because my previous EDC knives are sitting either in drawers or consoles of vehicles, but it was probably one of the best purchases I've ever made.
Also, their customer service is great. I sent my knife back to be sharpened/lasermarked, and the shipping on it got screwed up. It took a while for my knife to get back to me, but when I finally got it, they refunded the price of shipping/engraving, threw in a $30 tool/sharpening kit, and a code for $50 towards my next benchmade knife. I'm debating putting it towards another 940.
