Why use a Triangular file? - 12 photos

A "Triangular file" is literally your 'personal assistant' in helping you to clean up areas that any other tool cannot reach.

In these selected photos I'm aiming to show where & why this file is so important to you.

============================================

To clean the sides of claws on a Princess-cut claw can you think of any other metal tool? I'm not including Pumice Wheels in this exercise.

After the stone is set, there must be claws with symmetrical designs/patterns. 

 I used two shapes of finished claws on this Princess-Cut ring. I personally prefer a flat top pattern. The reason is that it has the same design as the flat stone, the round claws just don't blend in. 

I prefer to to use the mid-area of the file to shape the claws, but not the point of the file.

By laying the ring on it's side, I have a greater chance of succeeding to file the sides of the claws.

After the hammering the Channel Setting, I 'will & must' file the inside of the Channel Wall before the top of the Channel has started. This will give me more metal to trim and filing an even cut.

When the trimming has started, it's incumbent upon the setter to use a sharp edged file. 

The Triangular file is another tool for trimming metal around the mini-Full Bezels as shown here. I'd be using the smallest part of the file to clean the 'joining of the bezels'. 

 These little ink-spots let me know at first glance the grit of each file. I don't want to stop and examine each file.

On a Princess-Cut ring, there are 4 claws agree? But there are 8 SIDES TO FILE. Please don't use any Emery paper. We are trimming the claws with the greatest of care, don't abuse the claws with paper emery disks.

Here are my Triangular files with the ink markings that I use for easier grit-identification.
