What is the difference between Flats, Magnums, Stacks and Micro Blading tattoo needles?

A Flat tattoo needle is a single horizontal row of any number of needles.
The smallest Flat is a 3 Needle Flat and the largest in commercial production (by Unimax)  is a 49 Flat single row Flat

What is a Magnum tattoo needle?
A Magnum tattoo needle is a single row of an odd number of needles the distal ends being first
soldered together then each even number needle, for example, the 2nd, 4th, 6th etc can be bent upwards
about the diameter of the needle. It is found that it more easily fills areas without
slicing the skin when moved horizontally as happens with a single row Flat of unbent needles called a Flat.

A Stack is a number of layers of any count of needles needles solder together,
one row on top of another.

What are Micro Blading Needles?
Unimax has been manufacturing "Micro Blading" cluster needle "heads"
(without the bar) for decades consisting of an equal number of needle flats
one row soldered on top of another. Unimax regularly makes then
6 high. Unlike a Flat Tattoo needle which is a perfect square
Each row is made so that the points form the hypotenuse of an equilateral triangle.


Magnums are Slightly up/down Stack is like pancakes.

Magnum is one row of any odd number
of needles.  Every other needle
is bent up wards a .35mm angle.



Stacks are two (could be more)
layers one right on topof the other. 
The top layer has one less
needle than the bottom row.
