### ⭐⭐⭐⭐⭐ I have all 10 fingers, and I would like to keep it that way.
*by B***T on May 13, 2025*

I have all 10 fingers, and I would like to keep it that way. If you have no riving knife or separator on your table saw you need this.

### ⭐⭐⭐⭐ Measure your saw first!
*by U***W on March 16, 2018*

This looks like a great product, but I wasn't able to use it after I installed it. I have two Microjig Gripper push blocks that I really like, so I think the company makes great products & this one seems well thought out as well.My error made it unusable, so I thought I'd keep others from making the same mistakes.First is the kerf width. I didn't remember buying a "fancy" thin kerf blade 10 years ago. Just went to one of the big box stores and pulled one off the shelf. Works out that a lot of the big box blades are thin kerf. So measure your kerf width. Thin ones are 3/32 ". I tried sanding the insert to 3/32", but the pins are 7/64" so I was thinning out the pins & didn't think that was a good idea.Second mistake was the distance between the back of the blade and the end of the insert. My saw had a thin 0.093 steel throat plate that sits on a 1/8" lip. I made a ZCI with a Lexan plate laminated to a 1/2" plywood so the actual distance was 1/8 shorter than the 2" that I measured from the top of the saw. With the splitter installed as far to the rear as I could get it the blade would only come up to 1 3/4" before it chewed the front pin in half. That's not a huge problem because I usually don't try to rip stock that's more than 1 1/2" thick because the saw is underpowered.The instructions say you can cut the pins to accommodate an obstruction so next time around I'll move the splitter all the way to the rear of the ZCI and shorten the rear pin to the thickness of the Lexan.BTW, installing the splitter at less than full blade height requires a bit of trial and error (or very careful measurements). You can't follow the instructions until you figure out that your full blade height is only 1 3/4" vs cranked all the way up.I'm hanging on to the setup in case I ever buy a full kerf blade.In the meantime, I'm going to try the metal pro set (in thin kerf!). The metal pro splitters are narrower front to back and only have two pins so I should be able to fit one of them in behind the blade and get full blade height.

### ⭐⭐⭐⭐⭐ A good option for an old cabinet saw
*by B***. on December 16, 2024*

My old Grizzly 1023 had a splitter, but It had been taken off years ago. I know that without a splitter, there is a chance for kickback, but it was such a PIA for doing dado’s.I decided to update this old saw with a new blade and looked into adding a riving knife or perhaps fabricating one but the design of the saw didn’t allow it.My brother had just finished restoring an old Unisaw and he had put one of these on and said he liked it.I made a new zero clearance throat plate and using the jig from the kit, drilled the holes for the splitter which all went well.The splitter itself is offset so depending on which direction it i inserted, the clearance to the workpiece can be adjusted. It removes easily for doing dado’s which is a great feature. Two are included if one gets damaged or lost.
