Thickness is 3/16" on mine.
But, don't let that deter you from getting one. Some would say that is too thin for a 10" blade. Not so.
They do everything a big knife is supposed to do. It cuts well, it chops decently enough and it's size allows it to do all those things a little knife can't do. I wouldn't hammer it into a granite cliff face and use it as a ladder, or chop concrete blocks with it, but, that's just me...

IIRC, some have had probs with the Santoprene handle's texture, but, mine has never given me grief so, YMMV.
Get one and be happy.
