Hi Oscar, I thought your English was great and I appreciate you making the effort so that we can communicate (that's my fault, since I only speak one language). I do have a couple questions related to topics you brought up in this video: 1. How do you decide on and eventually settle on the thickness of each ply/layer for each blade design? For example, deciding between a middle ply that's 0.7mm versus one that's 0.9mm thick. 2. Is there a type of epoxy you find most preferable for the composite layer? For example, epoxies on the market seem to come in a range of flexibility and hardness values (e.g., from those used in boat building to stiffer options for finishing applications). Thanks for your insight!
Thank you for the inquiry. I think your questions will be solved little by little if you continue to follow up my youtube channel. However, I will give you simple answers here. 1. The thickness of each layer is very important factor to build up the final functional features of blades. It is time consuming process, and I normally take more than one year, before I finalize the mass production blade's composition. It will be difficult to explain all answers here, so, please, stay with me here, and I will probably have some opportunities to share more information concerning this topic. 2. This is also very important matter. I tested many different epoxies. Some are strong, but loses feelings, some are not hard enough for composite layers to stay fixed on the wooden layer. So, I think epoxy is a kind of company secret. Specially, some Nexy blades are now being copied by other brands, but I think they can not copy the actual functional features, because they don't know what glue I use, and how much I use. Therefore, please accept my apology that I can not tell you more about this question. Thank you. Keep posted.
Whoa very cool, wasn't aware a new Joo Saehyuk blade was in the works. I use the old butterfly one but it's pretty banged up. I'm curious to know more about the JSH prototype, construction, weight etc? Did he actually have some oversight on this blade, Best!
Hi, thanks for the video, just have 2 questions 1- What kind of blade structures and tech do you expect in the future? 2- Does fish scales on the outer ply of the blade give better feeling? Also one more non-serious question: If you could put a composition layer made of Meteor Rock inside the blade, how would affect to the play? Thanks.
Thank you for watching and for the questions. 1. For the time being, ALC blade will dominate the market. (1) ABS ball needs more power and spin in attacking (2) Players are playing close to the table and wants to play with high speed and direct feel, in exchange of good feeling and power when they like away from the table. (3) Tables are changing and gives higher bounce than before, which gives better chance to win for the style of Harimoto and Mima. => Due to three factors, ALC will become more and more popular in the market. 2. The percentage of the surface shape affecting on the functional features of the blade will be very very small amount. But it gives psychological satisfaction, which is also important for some people. Personally, I don’t care about that. 3. The ideal feature of a blade is not much related with the mechanical data. So, I don’t think we need very hard layer to maximize the speed. The actual character of the blade is the result of all materials in a given specific size and combination. I hope those are enough answers to your questions.
Since you talked about 3+2 ply, if you were asked to make a 3-4mm thick blade, what core and carbon would you choose, ignoring if its gonna be for def or w/e , just what are the first 1-2 combinations you would test ?
I know we used to have very thin blades in the past, when we played with celluloid balls. But with ABS, I think 3-4mm blades have very little chance. There is a regulation for the ratio of composite layer compared wit other wooden layers. So, if we produce 3-4mm blade, the carbon layer should be very thin. So, it does not make sense to consider, when it becomes too light and slow. However, I was informed that ITTF will allow many non-wood materials for the blade composition without ratio regulation, then your question will become serious topic for many brand designers. Anyway, first, let me tell you hard material does not guarantee higher speed. And also, speed and spin can be trade offs. So it will be very sophisticated process to find the ideal combination. So, if I really have make a very thin blade, I would try to make it still flexible and spinny, but need to be solid with heavy layers to guarantee 88-92g, which top players prefer to play with. So, what about this idea? 0.5 mm Limba + 0.5mm ayous + 0.2 carbon + 0.5 ayous + 0.2 carbon + 0.5 ayous + 0.2 carbon + 0.5 ayous + 0.2 carbon + 0.5 ayous + 0.5 limba The reason I used many layers is to make it heavy and solid, even it’s very thin, and the reason I used two wooden layers as outers is to give good wooden & soft feelings as well as good spin, and the reason I used ayous and limba is to give this blade flexible response as a whole, even very thin. Thank you.
Difficult to understand your question. Pressing process will be only for gluing two plies together tight. There seems to be no factor related with “ratio”.

Awesome video, as a blade entusiast is awesome to see so much information
Very informative video, keep up the good work.

Best blades are those with less weight about 75-80 grms. Carbon or other synthetic materials, higher control offensive.
Very informative video, pretty good English :-)

@@nexy-oscar1284 This is such a great response. Thank you for your time and expertise :D
Very good explanation, thank you.
I have a question out of curiosity, does each ply get pressed before sticking them together. If so, to what ratio?
Difficult to understand your question. Pressing process will be only for gluing two plies together tight. There seems to be no factor related with “ratio”.
