Jointless Cores and Veneers

Most Butterfly blades that use joint Kiri core is said to be necessary, as Kiri is often uneven in density due to its fast growth.

IMHO, Xiom is marketing that quality. That does not mean that the others like BTY & Nittaku don't require it in their QC as well.

I tested a brand new Xiom Vega Pro recently. It had a splinter right out of the box. Their blade weight shows HUGE variance (I had a 77g piece and a 92g piece). One vibrated a lot. The recent one did not. Their QC is clearly at least a notch below those 2 brands.

If anything, the recent BTY blades (Freitas, Garaydia series, new MJ) are even better built than their earlier blades (line Maze).

I am not buying it; or at lease it would be their job to find cores that are in one even piece; Xiom does it and that's why I consider them the true leaders of the market re. high quality and morals standards.

In the March 2014 issue of magazine Table Tennis World, there was an interview with Michael Schneider of Soulspin. Schneider briefly touched upon the topic on veneer joint, claiming that other manufacturers source ready-made veneers that are already jointed together to make plywood, but at Soulspin they source their logs, cut them themselves and splice them together. They take care of the whole process from source material to end products in-house to ensure the highest quality.

In the interview, Schneider says the Roots series uses Kiri for the core. Here is a picture of one:



Here is the question. Why don't they do it with jointless veneers?

TTW：那Soulspin除了定制业务以外，还会有批量生产的产品吗？ Michael：量产的第一个客户就是Nittaku的大师系列，它的材料主要来源于意大利那边制作乐器的材料。一般常见的制作球板的材料是已经拼接好的木材，用来做夹板，而大师系列不是。我们是买的一整块木头，自己切，然后再拼接。从材料到产品，全部是由我自己亲自管理，保证产品始终处于高品质状态。

From what I read, Nittaku uses jointless Kiri for the instrument series. They don't seem to market that at all. Don't you think that's an even higher moral standard?
