What Is It?

Chipper blades?

-

Tile saw...

Sure

But not the piece in question

table saw

Table tile saw even, but not the piece in question.

It is a pair of feet holding a small piece of metal to the blade of a table saw. That's some great dexterity for feet but why would anyone want to work this way?

...dexterity for feet but why would anyone want to work this way?

Because they already cut off all their fingers!

It's not a piece of metal.. or toes, but now that you mention it. It would make a good toenail file.

It's the very last piece of tile for your bathroom that you have been renovating for the last 2 years...unfortunately the winter caught you by surprise and froze the water in the tile saw and you have dulled the expensive diamond blade and can't quite get the very last piece of tile cut properly so you must wear it down with this dull blade which is taking forever....like this answer...

It's an accident waiting to happen! Where are the guards?

Animal, vegetable, or mineral?

Mineral

Guards. For this old gal?

I can squeeze that blade.

Perfectly quiet.

Not dull.

Waster misting .guard away for pic

Is this a piece of ceramic used to clean and redress a diamond blade. I used to use a piece to dress the diamond blade on my rock saw.

Nope.

Hint.

Why is the portion touching the blade white?

Its a soft touch emergency stop for table saw test rubber!

nothing exotic.

I was just cutting some quartz and unlike other marbles and stones it gives off a pleasant sparking glow while cutting.

It's hard to get a picture that shows how neat this looks.

Why I do believe that is your thumb, Buckaroo!
