### ⭐⭐⭐⭐⭐ The Perfect Keychain Knife
*by M***5 on October 26, 2020*

At over $70 for such a small blade, I can imagine lot of people would dismiss the Spyderco Manbug with K390 steel as an overpriced novelty item. My response to this claim would be that they have clearly never used the knife. I purchased this knife after trying out the Ladybug, which proved a little too small in the handle for optimal use. The Manbug was released solely to address this limitation, and Spyderco hit a home run by releasing what I consider to be the best keychain knife in existence. This knife is basically a smaller version of the Delica or Dragonfly, with excellent grippy scales, full flat grind, and incredible K390 steel that outclasses most popular high end knife steels used today. This little blade has excellent toughness, edge retention, and corrosion resistance with very few compromises, and the result is an outstandingly sharp blade that punches far above its 1.95” length.It’s a very small knife, about the length of my pink when closed. I got it specifically for my keychain and keep it attached to a KeySmart MagConnect for easy detachment, and having a razor sharp blade always on you is quite convenient. Aside from heavy duty professional tasks, there should be very little that this small knife cannot do in everyday life. It keeps its sharpness for a long time and Spyderco knives come scary sharp from the factory.If you want the best keychain knife there is, this is it.

### ⭐⭐⭐⭐⭐ Great little knife, good fit, durable and sharp.
*by E***. on January 8, 2020*

I gotta say I am an edc nut and a big knife enthusiast. I will say that this knife is SMALL but mighty! It is such a great knife to throw into your 5th pocket. It’s incredibly durable, fits great and sturdy in your hand. And is a great work horse. The steel is completely stainless but is softer and will scratch and get dull easier, be smart with what you cut. I love this little guy and would definitely recommend. I added a photo next to the Swiss army alox minichamp as a size comparison.

### ⭐⭐⭐⭐ Sharp !!!!
*by A***R on March 14, 2021*

Why 4 stars, not 5? The tip is outrageously sharp and pointy. Sliced my finger upon opening first time. Well-made, but no good reason for the tip to be so sharp. I have since filed the tip, so now the knife is much safer while opening.
