Like my Ex - Unique, quirky, and a bit thicker than she looks in her pictures.

Don't get me wrong this is obviously a super high quality knife, and I like it a lot. First off, the locking mechanism is really unique and fun, and for this aspect alone I think that this knife makes an excellent collectable. It is stiff at first though, and I think this may turn some weaker/smaller handed people off. I got the Bronze version, and the color and design makes it seem like a steam-punk prop, but this baby is a great cutter with great blade shape and materials. It was amazingly sharp out of the box and still is - even with some heavy use. And heavey use this thing can do - it is a sturdy build and the lock is rock solid. the handle is actually quite thick and holds in the hand much better than I expected. - certainly a good knife for someone who wants something to hold onto, and not so thick that pocket carry is out of the question. I think that the Double Helix's strengths far outweigh its weaknesses and would recommend you buy it, as long as skinny/easy knives are not the only thing you can handle.

Hmmm I'd rock that... Yepp.

This knife is a perfect example of creativity and functionality. The locking mechanism definitely draws attention to the design and adds a unique new twist to any knife collection. Absolutely love the blade shape and handle scales. Solid blade!
Love this knife!

If youíre looking for a knife with a blade deployment similar to a flipper, you might be disappointed. However, if you want to add to your collection a knife that has an absolutely unique design, quality finish and outstanding craftsmanship, then the Double Helix should be at the top of your list!
Not a fidget toy for sure! Plenty to like though.

This is a great knife. High quality materials. Excellent craftsmanship! Super smooth action. Rock solid lockup. No blade play whatsoever.
Easily operated with one hand, but the release buttons are a little hard on your fingers.
Itís been in my pocket since I received it though...
Do not buy this knife

I love the stone wash and how unique it looks. The thickness is also great cause it add's to the over all style of a well made tool. What is horrible thou is the new mechanism to open it. I feel like the only correct way of opening this knife is with gloves. Even using 2 hands to open it doesn't really help much since the studs have sharp edges that dig into your fingers. The amount of effort it takes to open this is ridiculous and impracticable. I give it 2 stars for being stunning and innovative and took away 3 for poor execution that makes a $15 used Kershaw dragged through mud and sand feel like a silky smooth opening.
