Question: what is the little knife called?
Document: Very pretty even came with a cover the knife on the front is little more than a letter opener but the sword itself was very well put together.
a well made sword , well balanced,a great sword for it price ,the small knife ,is a little loose makes a  a good letter openera nice show piece , etc
The sword was awesome but the little throwing knife didn't go back in the shealth so I use it to open mail. Seem to be built well. It is sharp and cut a few shurb bushes with my wife.
Blade is sharp and clean. Sword doesn't wiggle or jiggle when moved, does stick to the sheath but that might lessen over time. Also the little knife is pretty lose in it's placeholder and falls out whenever it's moved.
Was very please with this sword when I got it. It's battle ready and well made very sturdy. The only thing I was a little disappointed with was the throwing knife Did not fit very well in the sheath and rubs agents the blade handle and can easily fall out when the blade is drawn.
It was as it said battle ready when it came out the box. I got it for my brother and he loved it. the only thing is the little secret knife shakes a little and might fall out the handle but the sword itself is beautiful. Great buy and the price was great too. I recomend you to get this sword.
For the price, this is an amazing sword. It has made recycling giant boxes much easier, as I can now slice them to pieces. The little knife is pretty lame, but I really don't care cause I ordered a sword not a tiny cool looking knife. This obviously isn't the greatest sword of all time, but for the price it's great.
Little things & details on the sword, like the paint was like a kid colored it. also, the case that it goes into was too TIGHT. So when we try & take out the sword from the case, its really hard and that's not how it suppose to be. Also the little knife doesn't fit into its spot right or else that was the way it suppose to be. The oil for the sword only had HALF oil on it, what a rip off.
like it says above this isn't to bad of a sword it's full tang and yeah the little knife kinda sucks and it's a little dual, but that's what ever, It's really decent for the price I was really surprised. It's a little stiff in the scabbard, but that's an easy fix with just carving out the sides a little. So yeah if you're want a decent sword and don't have a ton of cash this isn't a bad choice.
My bathroom looked like a crime scene. A little gorilla tape along the inside rim of the saya provided a snug fit. I put a small piece at the mouth of where the accompanying (and kinda pointless, pun intended) "throwing knife" (don't throw this thing and expect results, let alone significant injury!) fits too, as it has an annoying tendency to fall out every time you remove the katana or hold the saya at a downward angle.
Answer: yes
