    Nobody mentions that the sheath has a whistle built into it! Great knife and the engraving came out great!

    Review of: Tactical Warrior Tanto Neck Knife
  • Daniel

    It is advertised as a boot knife but would also make a good belt knife for its size. The clip for the boot is sufficient to attach to a belt. It came sharp. Nice balance. It does complement the Hibben version of the Arkansas toothpick. I prefer this version over the other because it fits my hand, must lighter, and is much more useful.

    OMG I loved it at first when I first got it. It writes looks and feels like a typical pen but it's hidden knife inside. I bought it for protection when I have to walk home alone and trust me when I say every woman needs something like this in their life . It's so easy to use and hold.

    Review of: Black Ink Pen Knife
  • Joshua

    I bought this karambit for $10 not expecting much from it. But it arrived only 3 days, and the knife came razor sharp. And I mean lightly graze across you arm and you are cutting hair sharp. The handle fits perfectly in the palm of my hand and is extremely comfortable. The knife is small than I thought, but I like it betting this way because it is truer to the original versions of the karambit. Absolute must buy!!

    Review of: SOA Vengeance Concealable Neck / Fixed Blade Knife
  • Eric

    It is fairly dull but would stab through flesh easy enough if need be and sharpening knives is no problem it stays in well even when combing hair and makes you feel like a secret agent no one will be the wiser and know you have a concealed knife in your hand
