20 Best Hidden Knives



Hidden knives are not the easiest knives to find using search engines, especially if you aren’t sure of what you are specifically looking for. But I did some searching myself and have compiled this list of what I believe and the twenty best hidden knives based on uniqueness and usability. Hopefully this will help you find a hidden knife that is best for you too!

Not only is it a good idea to have a means of protecting yourself where ever you are (kitchen, bathroom, office), but some people simply enjoy collecting hidden knives because of their uniqueness.

I don’t like selling fear, but think about what you would do to defend yourself if an intruder broke in to your home while you were in the shower? But what if you had an Eiffel Tower Statue with a hidden knife decorating your bathroom, or the Honey Comb Knife on you vanity, when the intruder broke in. That knife could change the outcome of the encounter dramatically!

Just like other posts on this site, the idea is to find cheap knives to the job, that’s budget friendly, not poor quality.  I hope you find these knives more interesting than a basic boot knife.  Maybe you’ll even think they’re cool knives!  So, with no further adieu, here is my pick for the 20 Best Hidden Knives:

  1. umbrella rapier 150x150 20 Best Hidden KnivesUmbrella Sword. The best defense for a rainy day! The umbrella sword conceals a 28” rapier. The blade is easily concealed and is released with a push of a button. The whole thing operates just like a quality 50” umbrella too.
  2. Honey Comb Knife 150x150 20 Best Hidden KnivesHoney Comb Hairbrush. This may be the perfect hidden knife for women since many women carry a hair brush with them in their purse, and often in their cars. Since this is more like a shiv than a knife, you do lose some utility in terms of what you can do with a sharp edge. But still, with a cruciform blade that’s nearly 4” long, it is still a great self defense weapon made of Zytel, a very strong nylon and fiberglass composite.
  3. black comb knife 150x150 20 Best Hidden KnivesBlack Comb with Hidden Knife. This concept is similar to the Honey Comb Brush in that it conceals a knife in an every day item. But this knife is made with stainless steal.
  4. Victorinox SwissBeat MP3 150x150 20 Best Hidden KnivesVictorinox SwissBeat MP3 Player/Swiss Army Knife. Though it’s not exactly a hidden knife, unless it’s in your pocket or purse, it’s a pretty cool multi-tool. It looks much like a regular Swiss Army Knife, containing two blades, a file, scissors, plus a swing out USB drive/ MP3 player.
  5. RED SWISS BUSINESS TOOL 150x150 20 Best Hidden KnivesRed Swiss Business Tool. Also known as the Swiss Army Stapler! It’s an odd combination that’s useful at the office, or on campus if you’re a student. Besides having a stapler, there is a staple remover, a knife, hole punch, optical gauge, and more.
