I read a post on a different forum saying that the Dotec blade(s) are technically illegal for tournament play because their core layer isn't technically continuous. Is this true and is there anyone that's able to take pictures of the various dotec blades to confirm this?
USATT Rules 2.4.5 The blade, any layer within the blade and any layer of covering material or adhesive on a side used for striking the ball shall be continuous and of even thickness. I'm wondering as I'm getting back into the game and there's someone at the table tennis club that offered to help me get registered so I can compete in a tournament. Many thanks for any input. |

The ITTF don't care about that. Hundreds of blades use more than one piece for the core. There's no need to worry about it

Ok, that's what I wasn't sure about... I think I'll be with USATT but the rule sets seem similar. I just don't want to get my new blade/rubber and learn it - then find out it's illegal for play.

Never hears of anyone checking a blade out. Short of pulling it apart it would be tough to prove too. The Andro blax series have dividing slats in between the balsa core dividing it up into a brick like structure. Never heard about it being illegal.
The rules does however state the playing surface which the core is not. |

In my opinion once it's glued it's as continuous as any piece of wood is, it's a non issue. There's so many unclear and badly written rules in the laws of table tennis you can basically through half of them out

It's continuous if there isn't any gap. I have the BTY KLH and the Sclarger Carbon have core plies that aren't one piece. They are jointed and continuous.

Yep. Donic's DOTEC blades use an almost identical "block core" design to the Blax series (cost savings, small pieces of wood are cheaper than big pieces).
Plenty of manufacturers (Stiga, BTY etc) use jointed core materials; it saves them money. Basically, if the big manufacturers are doing it, then it's legal. |

Jointed core material? What the crap are they doing! With high cost of most blades you would expect solid plys. That's like adding Pink Slime to hamburger meat. Just any way to rip off the consumer..bastards! BBC and Ross Leidy know what a great blade is without trying to fool the public. No excuse for that type of construction...shameful in my book.

Amen! And don't get me started on marketing claims (Donic Bloodwood 5 "Quick Allround"!!!) If you buy from a big manufacturer, it's legal (as said earlier). Simply put: If jointed plies save companies money, it makes products cheaper. Cheaper Products = More Products Sold. More Products Sold = More Money. And everybody knows how corporations LOVE money! P.s. The companies still give consumers larger price (than manufacturer spends) in order to make money... no surprise.

I wish BBC could make an imitation dotec blade... The very comfortable handle & the exceptional control is why i'm going to purchase one.

I think they've got patents (or at least copyright) on the design, which is why no other manufacturer has copied it. |

technically no, because the rules state that the racket must be made of CONTINUOUS wooden materials. The Dotec blades have fibers that cut horizontally to the grain of the wood
But the ITTF allows the Defence II, which has five plies in the handle and three in the head. So I guess its legal. |

I think it depends a little on your interpretation of continuous... it could be interpreted as continuous thickness or the same material through a layer. I've never heard of a blade being disqualified, so I doubt it's an issue.

Continuous simply means that you can not have hollow section in the CORE or any part of the blade. This is to prevent the uneven bounce of the ball. |

I've seen the inside of a Donic Dotec blade that broke along one of the fiberglass strips and it seemed to be an obvious violation of the continuous layer rule. For those unfamiliar with the Dotec core, it is altogether different then your basic horizontally laminated multi-layer blade, i.e. a blade made in the way plywood is made, whether all wood or wood+fiber.
The Dotec blade's core is vertically laminated with thin strips of what appear to be fiberglass spaced every inch or so. If you were looking at the hitting surface of blade with its outer skins removed, these strips would appear edge-on as threads crossing the head horizontally. |
