Welcome to Gaia! ::

This example uses the armmod from Alitura Figura [note: Cheshire Kid shorts equipped for contrast]
1. No cutters applied
2. Bewere of Wolf cutter removes the sheer shirt [most visible at waistline]
3. Cheshire Grin cutter removes the handheld flower [note: neckbow is added from Cheshire Grin]
4. The Surgeon surgical scissors cutter removes the draped plants
5. Bewere, Cheshire, and SurgicalScissors used at the same time

BW = Bewere of Wolf pose: claw shirt cutter [adds claw mark cuts in tops]
BW = Bewere of Me pose: bewere cutter [adds claw scars on chest, note: BW for the cuts but YA* for invisibility]
YA = Your Angel / Angel's Piercing pose: bewere cutter [adds earring]
CG = Cheshire Grin / Bow Cutter pose: collar cutter [adds collar around neck]
SS = The Surgeon / Snip Snip Scissors pose: surgical scissors [nothing added by pose]
PY = Pieces of You / Pieces of Fabric pose: short-dress scissors [cutter can reshape some dresses and skirts, many uses in this guide they will not reshape but instead provide a different alteration. This cutter is not found in recolors of the EI, only the original and its gen 2. Note: When functionality overlaps with SurgicalScissors, definitely works forward facing, but not always backwards.]
KC = Knife Party: The Set: The Musical / Party Knife pose: knife cutter [nothing added by pose]
AX = A Very Yandere Birthday / Birthday Axe pose: axe cutter [nothing added by pose]
PR = Niwamori / Pruning Pinchers pose: pruning shears [nothing added by pose]
HR = Shattered / Shattered Glass pose: hidden reflection [nothing added by pose]
FT = Happy Death Day pose: face towel [nothing added by pose]
HD = Hood Cutters: //// Note: If the HD* is rendered invisible the cut is likely intended, other listings of HD are likely unintentional. Some items will not 100% invisible every model of hood cutter.
HD2 = Hood Cutters: V2: HD2 can cut more layers than the a regular HD however they cannot be rendered invisible. // Perfect Aim/Blossoming Nightmare/Winter Fur [cutting type: Librarby] // Fantasy Flavor/Hide and Sneak/The Dread Executioner [cutting type: Unique]. Static Sibling, Draconic Delinquent, have a partial effect but don't really seem built as hood cutters/replacers.
CC = Collar Cutters: // see collar cutter appendix for full listing. it's the first post on third page
remember: some of the items have more than 10 poses, so sometimes the cutter pose gets dropped from a user recolor

+ indicates a single cut/effect.
+? indicates a cut that may not be intentional. [some it could be, many may not be, but could have uses]
/ indicates multiple items provide the same cut/effect.
* indicates the cutter's base pose/effects are rendered invisible [from the front, often from the back as well but not always.] when combined with the pose. Some poses obscure the cutter's spot so invisibility is irrelevant or unprovable and hence not flagged as invisible.
{*} indicates the contained cutter/s are made invisible by the pose, but does no cut/mod to the pose.

notes: While some of the same symbols are used in the notes section they do not have the same meaning as in when used in the code. The / slash / defines different cuts involved while the + plus + implies that both modifications are caused by a single cutter. A +/ B, means means the the first cutter has the effect A and B, while the second cutter only has the effect B.

example of a code from Rabbitually Yandere : +BW/YA +CG* - mods: fishnets /+ garters and shoes
Code Explained: Bewere of Wolf and Your Angel provide the same alteration. Cheshire Grin provides a second/different alteration and the collar of the cutter is hidden by this pose. notes explained: Bewere of Wolf and Your Angel cut modifies the fishnets while Cheshire Grin modifies the fishnets, garters and shoes

Looking to hide a cutter effect? Search for the cutter code plus an asterisk.
CG = pose modified by Cheshire Grin but bow remains visible
CG* = pose modified by Cheshire Grin cutter and bow is hidden
{CG*} = not modified by Cheshire Grin but bow is hidden when pose is equipped
Note: spoilers have to be opened in order to be searched.
