3D Pushblock System

A moving blade guard.

Kickback occurs when any side of the workpiece strays from being parallel to the blade. The GRR-RIPPER completely control both sides of the workpiece throughout the entire cut and virtually eliminates kickback. Your hands stay completely protected as the GRR-RIPPER glides over the blade.

Scuba Steve (5-Star Amazon Review)
I am always on the lookout for devices that will help me increase my safety margin...and the Gripper does that and more. I liked it so much that I bought a second, which allows me to rip longer pieces by leapfrogging Grippers.
Alex Smith (5-Star Amazon Review)
I freaking love this thing. It saved my project, and my sanity.
Paul Edgar (5-Star Amazon Review)
The first praise I can give is that I still have all the fingers. I find this tool to be well thought out and very useful. I use it mainly on a table saw, but it would work well with any tool that cuts long narrow pieces of wood and there is a danger of injury. Router, jointer etc.
Crsangel (5-Star Amazon Review)
It completely protects the hand while giving great control over whatever you're cutting. With the grippers on both side of the blade, there's no concern at all about a kickback.
Dr. V (5-Star Amazon Review)
I have used it on the table saw, re-sawing on my band saw, on my router table, my shaper, and my edge plane and have found it to be a tremendous help. I am in my 60's and not as agile as I was 30 years ago. Would like to keep all my fingers till the end.
