Question: What type of wood is it made of
Document: This is a good practice sword made out of quality wood and it looks just like the picture. The wrap comes unglued easy but can be wrapped up tight to easy to complain about. Good buy for this price.
My daughter had been asking for a Katana for sometime.. after finding out what one was visions of her older and somewhat antagonistic brothers body parts strewn about the house quickly filled my head... so I bought this instead and it is a great. Weighty and appears to be well made, good quality wood etc. Most importantly she loves it. Ship time was good as well.
This one looked pretty good, but I wasn't pleased with it. I had an earlier plain bokken made of oak which I liked a lot, and sadly gave to a friend. I thought this one would be similar but the wood was extremely fragile, mine cracked and chipped just doing some light sparring against padded swords. Aesthetically it's not altogether pleasing either, it's lumpy and irregular when you look close up. I'm trying to figure out which one I bought the first time.
The kendo sword got to my house in great condition. It is very well made and is just what I expected it to be.
This item broke at the handle right away. I thought it would be made better than this. I have a very upset grandson!
Sword was a gift for my grandson' birthday. He received it on time and was very pleased with the sword. He stated it was heavy feeling, quality made and realistic.
I really liked it, however it came banged up in a flimsy package, so watch out for that. One thing you should know is that the seperator, from the wooden blade part and the handle, does move around when using it. This part is made out of rubber and slides around. It is not secured.
Bokken is flimsy and looks as if it will break easy, and the laquor will scrape off. I have three other "real" bokken and this doesn't compare at all to those.I would not recommend using this in any real practice. All show, no go.Great big "made in China" sticker on the box too.
Bought this sword to practice and workout with. Is a great find for the workout or just collecting enthusist of Japanese-inspired equipment. The sword is nicely made and handles well. It comes nearly ready to use right out the box and looks good. The only drawback is the fact that the guard for the sword is not attached at requires some ingenity to attach properily and to stay attached.
The guard kept  falling off. I had to put tape on it. The wood was strong though. I wished the guard stayed on.
Answer: yes
