What circular saw blade for plywood?

I’m using 6mm exterior WBP ply on my project, but the ply chips badly with my standard circular saw (hand model, not a table saw).
Looking through my wholesalers catalogue, I see a huge range of alternative blades ranging from 18 to 80 tooth.
What would be most suitable for my project? Your help, as always, is greatly appreciated.

 

hello
It has been my expierence that a fine tooth blade is best for plywood. The 80 tooth option sounds fine.
Good luck.

 

Score your cut line with a sharp knife or cut from back face without too much blade protruding.

 

Handy advice, thanks fellas!

 

Roly is right a rule of thumb is to let only the carbide tooth protrude through the work no more, you will be fine.

 

Many, many teeth. And marginal depth (which doesn't track as well, so a straight edge would help). In addition, if you really want a perfect cut, and you own a router, get a bearing-piloted flush-cutting bit and first cut with the skilsaw to a sixteenth from the line. Then clamp a hardwood straightedge to the wood ON the line, and use the hardwood board as a guide to produce a super-square, super-straight finish cut.
I used to use this meathod to build cabinet faces before I got a joiner. It's very accurate and controllable.
