I don’t often write about tools I use in my shop – you see them in the background of photos taken for my posts. I have only a couple tools or machines that have immediately changed the way I woodwork. While this tool is not one of those two, it is one of only a handful that I feel should be given extra consideration. The tool, as you can see in the opening photo, is the GRR-RIP Block. (It’s from MicroJig, the same folks that make the GRR-RIPPER 3D Pushblock, which is another tool I turn to when working with small pieces.)
Since this newly designed push block came into the shop, it’s been at my jointer. I use it almost every time I surface material. The reason I use it is that it does the job easily. No matter how I pick up the GRR-Rip Block, it’s ready to use (unlike shop-made push blocks that are good only in one direction). 
The hooks (the company says Gravity Heel technology) are great. The two hooks on the end that ride the board easily pivot up into the tool, flat and out of the way. The two hooks on the opposite end, drop to catch the board’s end – it doesn’t matter which end of the tool is which. The handle has a slight bend to one side, which should be held out or away from the fence. But because I ride the work piece at an angle to the blades whenever I can (see the photo at right), I don’t worry about having the push block oriented every time.
I also like the GRR-RIP Block’s non-slip bottom surface. It grabs the hell out of rough stock and is just as good on smooth surfaces, if you keep the bottom clean.
If you’re looking for a push block, I’d suggest you look at the GRR-RIP Block. (I have no connection with the company other than I think its tools are innovative and extremely useful.)
