Debating on getting a flush wire cutter....
I saw someone using the flush wire cutters so I thought I needed them and, honestly, they come in handy. But, while waiting for them in Vapemail, I learned to use the nail clippers and stress breaks with efficiency. The flush snips really help to get under a coil to snip a positive leg on four post decks.
I mainly use a cheap small screwdriver set (3mm - 1.4mm), tweezers, toe nail clippers, small sewing scissors, and a multiuse pair of pliers (needle nose). Ohm meter, multimeter and intelicore i2 batt charger on hand at all times.
I have various types of wicking: Japanese Cottons, Raw Texas Cotton, Cotton Bacon v2, Silica Rope.
And a couple of types, in various sizes, of wire:
Nichrome 80 - 22, 26 & 28 gauge
Kanthal A1 - 24, 26, 28, 30
At times i will use a drill, large and small pliers, various screwdrivers, push pins and the tools that come with the rda/rta/rba kits.
I use laptop computer boxes with foam inserts to hold juices and mods and a compartmentalized tackle box for all of the vape tools.
