Question: I would like to ask if the blade is fully sharpen
Document: I just received this sword as a gift and it is beautiful!!! The red lacquer of the wood is amazingly done. The shine of the blade is also amazing and decently sharp.Not sure if this is a full tang, which would be even more awesome, but it is a beautifully done replica.Oh and the box that stores the sword is a little cheaply made but still adds an awesome touch
The sword may a lot of vibration on contact and may feel like it is not full tang but I assure you it is. Good beater, just dont cut anything too hard
I received my zatoichi cane sword a couple of days ago and  and  I  am very pleased with it, It's very sharp.it came in a well made wooden box and and in a black bag to preserve it, for the price I couldn't  ask  for a better sword.
I was worried about this purchase as it was not very expensive for a sword. It is simple and well-made. Now, beware... my daughter (2yrs old) grabbed the sheath and banged a few times on the floor which chipped the paint... so don't do that. My husband cleaned up the blade as it was EXTREMELY sharp and a bit oily. I will definitely buy from BladesUSA again. You should too!
the sword came 2 days early that was awesome.the box was clean and perfect.the wood box it came in was nicer than I thought it was going to be and makes a great display piece.the red finish has a few blemishes but nothing to serious.the blade cuts great.this sword is worth the money.Just buy it you'll be happy.
It looks like Zatoichi'sKatana, and is easy for operation ! You will love it !
its very handy and for another  if u like the no guard  style then this sword is for u its nice and long and very nice and slieak and beautiful
Also the blade has some flexibility and can be honed to razor sharpness with ease. Note: it comes sharp out of the box. As far as the finish between the blade and the brass blade collar (habaki) it needed a little work to spruce it up but nothing to be overly concerned with and it could have been ignored. So if one is looking for something that is an economical and practical shikomi-zue then this may be the item.
Upon opening the presentation box, the bright fire engine red lacquered Zatoichi sword makes one think that it will be the first thing that anyone will see. That is absolutely correct, but outfitted with a custom made rubber boot, some added rattle reduction material in wood scabbard and a bit of blade honing to razor sharpness and it seems to be accepted by those who see it as a walking stick Zatoichi, a practical device.
Very nice & sharp, worth more than the asking price compared to others on the market. Glad I made the purchase.
