    Awsome box cutter. Allows me to protect blade on my custom swiss army knife. My keybar with mini utility and bottle opener makes my everyday carry complete.

    Fantastic idea and I use it every single day. Still playing with washers yo stop it from accidentally slip outwhen I grab a key. But I would highly recommend this, extremely convention

    Makes your keybar looks sick, keep in mind this needs to be the first or last of your inserts so the tiny stoppers hit the keybar itself to work as intended. Its just great to always have a utility tool on hand, ALWAYS.

    It cuts and stows nicely. You need okay tension to hold it in place but it works well.

    Good addition with my screwdriver combo and pick insert along my 7 keys.

  38. Jim (verified owner)

    love this insert. Super sharp, cuts through card board boxes like its nothing and convenient. would be better if the replacement blades can be purchased through you guys instead of having to go to another website just to get them.

  39. Max G. (verified owner)

    The one insert I thought I wouldn’t use in the one i use the most. It’s the best.

    Good piece to have. Maybe a way to retract the blade could be added in a newer version but still useful.

  43. Rick Betti (verified owner)

    Another great add to your keybar

    Great little knife

  45. Jaya (verified owner)

    Love this insert soo much. Bought another for my other KeyBar.

  46. Chris D. (verified owner)

    Takes up a lot of space, but blades are sharp and good for fine work, good for crafts.
    Comes with lots of extra blades, I didn’t see replacements for sale on the site, and would be nice to be able to purchase rather than the entire tool

    My grandson loved his gift. A happy camper
