Since there's little to no information out there on this little guy I'd like to post my initial thoughts. Let me get the negatives out of the way right off the bat...This knife is expensive. Like many of you, I was intrigued with this knife when I first saw it at shot show but I suffered a severe case of stickers shock when I saw the price. Is it worth it? That is up to the user, personally I would say no and here's why. This is a purpose built knife made from quality materials by a reputable manufacturer. One could argue any knife that costs more than a rat 2 or a mora is overpriced when at the end of the day they all cut. A $10 Casio is more durable and much better at telling time accurately than the most expensive Rolex money can buy. At some point it becomes less about functionality and more about user enjoyment/pride of ownership. This knife fortunately offers both functionality and pride of ownership.
Second con, and this could be isolated to first production run status...my sheath is STIFF. Like past the point of good retention and teetering on unusable. I will be spending some time drawing and re-sheathing in hopes it gets broken in before actually carrying this out and about. While on the subject of the sheath, more mounting options/eyelets would have been welcome. I was still able to Jerry-rig an izula clip on, but lower than I'd have liked.
Now on to the good. For me, this knife is exactly what I've been looking for. I'm of the opinion that finding a good knife is just like trying on shoes; as soon as you put the right pair on you just know. As soon as I opened up the box (and wrenched the knife out of the sheath) I knew it would be a keeper. The weight (or lack thereof) took me by surprise. I believe that is partially why you will pay a premium for this knife. It weights next to nothing and still has great ergonomics. The altitude has all the right jimping in all the right places that lock your hand into place without feeling like you're grabbing on to a cheese grater.
Next up, like the Benchmades of old the grind on this thing arrived flawless. It's literally perfect and cuts like a freaking light saber. I've never used s90v before but from what I understand it functions similarly to zdp-189 like on my dragonfly 2, meaning it will hold an edge forever but will be a mother to sharpen and more prone to chipping. Well, before purchasing I did as much research as I could and landed on born and raised outdoors YouTube channelwhere those guys processed an ENTIRE ELK with an Altitude. I would venture to say that is more than what 90% of the people who buy this knife will do with it, myself included. After processing they ran a few passes on a worksharp and it was back to popping hairs. Perfection.
I'm still well in the honeymoon phase, but overall impressions are very positive. I'm going to be keeping my ZT in my backpack for a week and use the altitude as my EDC. I'll try to update any thoughts or concerns. Thanks for taking the time to read my ramblings.
