Twin Trak Dual Chamber Utility Knife (Ambidextrous Deployment) Backup Blade Holder for Keychain or Carabiner Type II Hard Anodized Aluminum Body Spring Steel Lever Black

Within minutes of seeing an ambidextrous offering from Screwpop, i had my order in. The sheer rarity of a utility knife usable in the left hand was enough, but the regular Screwpop knife I own told me that this other knife would also have a high level of affordable quality. For the right handed, nothing changes. Use the blade as needed and rest assured that a spare blade is waiting when the regular one dulls or breaks. And for us lefties, the same is true. Finally.I like to think it was my email asking for a left handed version that made this happen. Who knows? Either way, I am a satisfied owner.

This is the barest necessity in a utility blade holder. The blade lock up is wonky because there is forward and backward play. I'd prefer a blade that locks up tight without any forward and backward play. Practice is needed to open and close the knife. I do like that it can carry two blades.

Cool little knife. Fits everywhere. I just keep it in a backpack in case I need somewhere.

Nice design, but the blade holder point should be thicker so the blade doesn’t move

I've been an enthusiastic user of Ron's Utility Knife 3.0 since 2019. I carry it on me more than my phone. Then this thing came along! Such an improvement on a tool I already loved. It feels better in your hand when cutting. Sliding the blade in and out is easier. The new lever feels great to operate. You can use it one-handed with little practice. The ambidextrous design means it can hold a spare blade. Thinner body means its easier to put on a keychain. It looks way cooler. I'm not missing the bottle opener from RUK3.0. This is my main pocket knife now, and I use it multiple times a day. I love this thing.

Beware. Blade comes out on it's own. Dangerous.

This is a handy little utility knife. It’s just a little bigger than a standard blade, which is a great size for sticking in a pocket. It seems to be super safe. It does take two hands to open, but that also makes it feel safe.I think it’s a great design for a fantastic price. And it takes standard razor blades, so it’s cheap and easy to refill.

Sure, a blade can move a bit in a utility knife, but not in one as compact as this.Simple fix would have been to roll the end on the tension-lock, so it fits both sides of the blade retention tight. It would even engage easier, as it would guide itself into a sure fit.Not an engineer, just a pragmatist.Feel free to send me a case of them when fixed, and I won't go patent my own. Lol.
