The best blade I ever owned ! Incredibly fast but soft in the hand, you can easily block, loop, smash, absorb adverse energy or inverse the point... of course as it is very fast, you can't use fastest rubbers or you will kiss the walls rather than the table... unless your name is Timo Boll, of course ! but with average hard tensor rubbers (40°) or chinese ones for example, this blade let you do anything. Another way to play table tennis... really great !

This is my primary blade and I play twice a week with it. It is the best one ply you can get. The quality is great and the speed is the best out of all one ply hinoki blades. I use Bryce Speed FX on FH and Solcion On BH. Is not as fast as the carbon blades but the control you gain is worth the trade.

One of my very good blades. Very good for loop FH & BH, block, short games...Can't complain. I have it with T05 for FH and Donic Acuda S2 for BH (very good combination).

I would like to explain why this blade is the most amazing one I've ever played with.
First the feeling is beautiful, the blade featured just 1 ply of finest premium quality hinoky wood, this means that it is soft in the hand, medium flexibility that allow you to have extra spin when you top and have precise blocks and smash. The vibrations don't exist.
The fact that it is so thick, soft and medium flexible make it to have so many gears, you can push very fast and very spinny but you can easily control it when the game in slower.
Finally i cannot find something wrong in this blade, for me is speed 9.5, control 9.5, feeling 10. The price is high but you have something unique, best handmade hinoki wood quality and you'll never change it..at least probably :) Last point for me..I prefer give my money to Darker Ltd, that is a small high quality blade company instead of give them to multinationals..but this is just a personal point of you....:))

I posted a review on this blade here:
