The 28" Plastic Stirring Paddle is big enough to stir up the mash for a ten gallon batch, and works well in larger volume kettles, fermenters, and mash tuns.
It wont work with a thick mash but is good for a very thin mash. And it's much less expensive than one of those wood paddles.
This paddle is great for mashing in. Good quality and fair price.
I use this inexpensive paddle for everything in my brewery. Works well to stir wort during kettle additions as well as having one to stir star san solution and pbw solution.
I use this during every batch. I love it for aerating the wort. The slits make it so much easier then any spoon. This works in my 10 gallon pot easily.
