Welcome to the FAT PP Club!
Why is it called the FAT PP?
Yes, you now have a FAT PP in your pants. It actually stands for Folding Action Tanto - Pants Pocket. We just happened to like the acronym! It’s purpose-built to give that tiny 5th pocket on your jeans a real reason to exist.
What are the exact specifications of the knife?
The FAT PP is designed to be sleek, snag-free, and ultra-compact. Here is exactly what you are carrying:
| Blade Material | 8Cr13MoV High Carbon Stainless Steel |
|---|---|
| Handle & Backspacer | Stainless Steel |
| Closed Dimensions | 2.0" x 1.1" |
| Open Overall Length | 3.2" |
| Blade Length | 1.2" |
| Thickness | 0.31" |
Is this the newest version of the FAT PP?
If you’re reading this, you are holding the 3rd Generation FAT PP - officially released in July 2026.
With tens of thousands of our previous generations already in the wild, we’ve combined our strict carrying standards with invaluable customer feedback to make Gen 3 our most refined design yet. We scrutinized every detail to elevate your experience.
What’s new in Gen 3:
Enhanced Ergonomics: CNC-milled chamfers and precision spine jimping deliver ultimate comfort and maximum grip control.
Flawless Action: Upgraded phosphor bronze washers paired with a completely redesigned frame lock ensure smooth, reliable deployment.
Sleek Finish: Custom flat screws provide a perfectly flush, low-profile appearance.
Updated Branding: Our new "S/L" mark sits proudly on the front face, while the classic FPP logo has been relocated to the back for a cleaner aesthetic.
How do I sharpen my FAT PP?
You should be able to sharpen the FAT PP knife just like you would with any other knife. Sharpening steels and blocks work especially well. Some sharpening jigs may be difficult to use since the FAT PP's blade is so compact.
Can I take my FAT PP apart for cleaning and maintenance?
Yes, of course! Sometimes it's a good idea to do the occasional deep clean to get rid of all of the accumulated pocket lint and dirt. Assembly and disassembly are extremely straightforward.
Hardware Specs: The main pivot screw uses a T-9 torx bit and the two rear scale screws use a T-6 torx bit.
How do I properly clean my FAT PP?
We advise using mineral oil or an eraser to remove stains from the high carbon stainless steel blade. Cotton swabs and paper towels soaked with IPA (Isopropyl Alcohol) will help remove unwanted debris on other parts of the knife.
We also highly recommend using a viscous lubricant on the pivot and along the detent path of the blade to ensure the phosphor bronze washers maintain their smooth deployment.
What is the warranty policy?
Your FAT PP is backed by our Limited Lifetime Warranty. We guarantee it for a lifetime against defects in material and workmanship. We also offer a 100% Satisfaction Guarantee - if you aren't thrilled within your first 14 days, reach out to our support team.
