Is it commonly used in all builds you make, why do you use it often, etc.
I like using the Demon Great Machete for my builds. Strength weapons are used too little now, and they have so much potential. Takes a lot of work to get used to them, and they're outclassed by a lot of dex weapons.
Estoc. Fast, low stamina consumption and overall a great weapon. I grab it as soon as I'm out of the Asylum. Take it to Fire->Chaos if I'm going non-dex builds. Gets the job done in PvP and more than decent in PvE. Light as hell and even when I've moved onto my primary weapon, it never gets boxed as it often becomes my offhand poker/parry weapon or a secondary weapon.
Usually fast dex weapons. Love the BSS and uchi. Other times I use the claw or even the large club (to hunt gankers on my str build). I use a lot of different weapons and make builds to use a specific weapon most of the time.
