Black FAT PP Knife

100% Satisfaction Guarantee

Show everyone you have a FAT PP™ in your pants. Let your friends hold it. Bust it out at family gatherings. Everyone you show it to will be jealous and wish they had a FAT PP too. 

We spent over a year creating this knife from the ground up to fill our personal EDC requirements. No snag points. No bulky screws. Thin AF. No unnecessary features.   This knife opens boxes. It cuts wire. It's a conversation piece. And most importantly, it fits perfectly in your 5th pocket (that tiny pocket that nobody uses). You won't even notice it's on you until you need it. 

Whether this serves as a back-up keychain blade, or as your primary 5th pocket carry, it’ll always be within arms reach when needed and invisible when not. 

Closed Dimensions: 2.0" x 1.1" 

Open Overall Length: 3.2" 

Blade Length: 1.2"

Thickness: 0.31"

We use a 8Cr13MoV high carbon stainless steel blade which means less time sharpening. The scales (handles) and backspacer are also stainless steel which gives the FAT PP a hefty feel. 

Limited Lifetime Warranty:  We guarantee a lifetime against any defects in material and workmanship.

In the unlikely scenario your FAT PP breaks (oof), shoot us an email at and we'll replace it free of charge. Damage caused by normal wear and tear, misuse or abuse are not covered by this guarantee, so don't beat your FAT PP too hard. 

Contact for any questions/address changes.

It has a great personality

Everyone loves my fat PP

This pretty above averaged size tool fits in my pocket and doesn’t bulge like you’d think. I’ve gotten lots of compliments on my fat PP and have used it quite a bit since receiving it. My girlfriend is scared to touch it but she quickly got over the fear one she held my black fat PP.


My knife was so nice a customer stole it off my cart at work. I work at a grocery store so it was expected😭 wish I could afford another one
