I thought that a blade made in Japan and specifically by nittaku was supposed to be high quality error free and unquestionable performance. What happened? The blade played like crap so i measured it and showed 157x150 instead 156x149. So i said what the hell it is not a donic or stiga or dhs! It is holy grail nittaku. So i decided to make the handle bigger to suits the heavy head.so i prepared a timo boll fl handle and decided to change it. To my big suprise it was not even. It was like the picture showed unprofessional and disgusting. How can i play a full stroke and having confidence that the ball would go exactly where i want.i felt down and frustrated.
One thing i like to add: butterfly should charge a 1000 usd for a timo boll or mizutani for their error free unbelievable quality control, each blade they make are pure perfection. Sorry butterfly that i once said that a viscaria at 165 usd is a rip off. You really don't have any competition out there. Hat down.

The router guy was glancing at the pretty girl who happened to walk by at the time, he handled it poorly Confused.

"nzoiiing!"

... 

"oops...oh well, they won't know."

Seriously, I am confident Nittaku will replace the blade, I am almost 100% sure of it. Did you contact them? Maybe you could edit your post where you compare with other brands.

Some info about them:





Good luck!

Sorry I don't care replacing it or having my money back. I earn a lot, it is not the issue. The issue is, there are poor guys out there who spend a lot for something special and they are not getting it and I thought they should know how to buy and don't let there year of sweat and practice be ruined by a bad blade as I believe that a bad blade would make you lose confidence and make you loose matches no matter what and how much good you are.

It doesn't sound like you want to solve a problem, but create one.  If they made a bad blade I would think they would replace it.  You seem to want to damage their reputation because of one bad blade.  If getting a bad blade makes you as angry as your posts indicate, you must have other issues.

I don't think it is one I think there are thousands out there. They should recall them and fix their manufacturing process.

Are there any blades where the handle isn't hollowed out like this?  I use Acoustic carbon which I assume is the same as this (I'm not going to take one of mine apart), and I'm very happy with them.  But it would be interesting to feel a blade that is head-light, not just evenly balanced.

I have had Nittaku Latika once and it was impeccable. I didn't dismantled its handle, though.

How many blades, besides your own, have you found with this flaw?

It is not the hollow handle that is wrong but the dispoportion in the cut of the empty hollow and the head dicrepencies between the catalogue and the one I got.

Nittaku have a costly cutting machine of SHINX for making the hollow slots in plywood blade. Nittaku is a Patent holder for the hollowed racket blades.

If you look closely, the left side has an asymmetric extra bit of wood compared to the right.  That is what he is complaining about.  It isn't clearly by design.
I like putting heavy topspin on the ball...

They must use a vacuum plate to hold the blades and it probably moved when routing the hole for the handle. No reason to scrap the blade when the issue isnt cosmetic since its under the handle and doest effect performance. As for the size being off 1mm. I believe the "instrument " line of blades have more hand finishing so less than 1% tolerance from spec is surely within limits for the  O.D. of the blade. Sorry you are not happy with your Violin.

I have two Nittaku Violin Carbon blades, one which I purchased when it was first released and one which I got more recently.
The older one measures exactly 150 x 156mm and the newer one 150.3 x 156mm.
This seems an acceptable difference and when you consider that the most common blade size is 150x157, it makes sense that they err on the side of making them slightly bigger rather than smaller.

The misaligned cut in the handle is obviously not acceptable and should not have got through quality control, but once the handle is attached it would have made it almost impossible to detect.

Yes the head size is bigger by 1mm x1mm. But the handle that is the component that drives all the balance at high speed and the feeling of the blade is done wrong. This is a violin carbon inner by the way.

HOLLOW HANDLES

https://forum.tennis-de-table.com/t/manches-creux/7628

The JOOLA K4 series is the best.   The true purporse of all the hollowed handles and blades is to give you a sharp feeling in your hand.

1mm is too much, computer controlled tools work at sub milimeter precision but I got a nittaku blade some years ago with missaligned badge..people claim that tt gear made for japanese market has better quality but is not true

Guys, if you pay a big premium for a handmade blade it will have imperfections. Get over it

CNC machines are capable of sub 1mm cuts, but that doesn't mean that a tt mfr has a CNC machine capable of making those cuts. Maybe they have a very accurate machine but choose to make cuts at a lower level of tolerance. More accuracy costs more $$$. The mfr factors the cost of operations versus what accuracy is actually needed.

They are cutting wood. Wood is a porous material that expands and contracts with humidity. Wood from one part of a tree will have slightly different properties from another part of the tree.

Add factors like these together and you will get some measure of manufacturing tolerance. Blade weights are +/- 3-4%. A sub 1% dimensional tolerance sounds reasonable for a wood tt paddle.

For comparison, if you go buy a new $500 golf driver, just about every mfr quotes a +/- 1 degree tolerance in loft/lie/face angle. If you buy a 9 degree driver, it means the club you are buying has loft of 8-10 degrees.

Based on three OSP blades, it will not.

Given the prices they charge this is awful.  This goes beyond imperfections.  It suggests there is zero QC.

I have three acoustic carbons.  One I bought new from TT11 and two used here from different sellers. With my rubbers on they all weigh 173 gms.  And I didn't specify weights obviously since buying used.  So with my very limited data set Nittaku QC seems pretty damn good.

That is because osp CNC mill their blade. I don't really care about hand made and prefer perfect CNC but hand made items are never identical. Humans just don't work like that
