Beautiful little knife. Slider functions well. But, my bad for not reading the dimensions, too thick for your wallet. There is another item like this out there "somewhere" that I can no longer find. It fits right in your wallet, just like this one doesn't.

So it is simultaneously really cool and stupid at same time. Had one when I was younger. Looks neat but not a particularly ergonomic or useful tool. The one sent to me in particular is extremely tight when closed thus difficult to deploy. Ya feel like you're going to accidentally cut your fingers off trying to get blade out. That being said I'd still recommend it. It's cool.

In a state where spring assisted opening and gravity knives are illegal, this knife is the answer. It's light and easily carried in a watch pocket. In a critical situation where a folding blade would be awkward, this knife opens with the flick of the thumb. Great, thoughtful design.

Other than being plastic and rather cheaply made, overall I like the knife.Double edged and very sharp

Blade lock does not keep the Blade locked open

Had this knife back in the 80s and loved it!!! Lost to time and for whatever reason thought about it the other day. So, I thought I would look it up and there it was. Really cool fat little blade tucked in a slim case. Came in a little Tekna knife holder storage "briefcase" kinda cheesy but it did put a smile on my face. It's just as cool now as I thought it was then. Glad it's still available!

Tekna is a good, solid knife

Great little knife. Wanted one for years got one, lost it and then saw it was available again so I got 2. One of my favorite old shows, SOF Inc. used one and having one bring back memories. Shape out of the case, a nice touch, the knife comes with a padded case. Only used mine to open a bag of soup so far but I know I will do more with it. Worth, to me anyways, more than I paid for it. Very covert. In fact I went to a family court trial with it. I keep mine in my wallet and since my wallet didn't got throread moreugh the metal detector I was more than likely the most armed civilian in the whole court house. Had I been thinking I would not have brought it but just goes to show how this little blade can slip in under the radar. I am very happy with my knife and plan to order more to outfit friends and family.

Heavy and hard to hold.Would not like to push too hard on handle since no 'purchase' (grip).The concept of a 'billfold knife' doesn't hold up.This is to throw in a car kit, maybe.
