Our Biggest Force Multiplier
The "Big Nasty" is our largest low-vis EDC tool. Wrench, screwdriver, bottle opener, keychain—this impressive force multiplier delivers heavy-duty capability virtually anywhere you can carry your keys. Engineered for compliance in non-permissive environments, this tool ensures you have real mechanical advantage where traditional gear isn't an option.
Precision Engineering & Strength
Anodized black and laser engraved with a unique serial number. It’s both a precision-crafted collector’s item and an incredibly functional force multiplier.
Ergonomics & Structural Support
Featuring precision designed ridges and crests that enhance energy transfer by up to 800%, making it potentially useful for emergency glass breaking. The loop ensures absolute retention, even under stress, and the ergonomic shaft reinforces the metacarpal bones to help prevent injury during high-impact tasks.
Versatile Carry & Travel Readiness
The built-in bottle opener, wrench, and pocket carry slots add daily practicality. It rides comfortably on a keychain, in your waistband, or clipped to gear with the included S-carabiner. TSA-friendly and commonly brought on commercial flights, the Big Nasty is arguably the most capable travel-ready EDC tool ever made.
In short, it’s the hardware you’ll be glad to have in your hand when the pressure is on.

The Bone V4 with more attitude
Nice craftsmanship
Solid tool
Love it
Can definitely crack open some nice coke bottles with these if needed in a pinch. Cigar punch option works extremely well too. I didn’t think it would be good at first for cigar punch but I love it!
THIS THING IS ELITE..
I WAS A BIG FAN OF THE STAINLESS STEEL BONE BREAKER WHICH WAS MY FIRST, AND I DO RECOMEND IT
BUT THIS B.I.G NASTY IS OFF THE CHARTS
GET 1 ASAP IF YOUR INTO THAT.
GREAT EDC TOOL
🤙🏽
Well made, fixes a lot of problems trad dusters have, comfortable and super strong construction. Never thought i would go buy a duster again after using trad ones, in multiple situations over the years, go figure...I'm converted to this one now..... you got yourself a new customer ...
I got this for what it is a disguised force multiplier! I know it would add weight but I would almost want one in stainless steel. When I close my hand I feel it flex but other then that I like it and have carried it even with my other edc items!
The big nasty was to all expectations. It’s discreet. You always have a peace of mind that you can handle almost Hand altercation if needed it holds up really nice. It’s in the pocket two ways.
Pretty slick piece of EDC
This thing is just awesome. Solid piece without a havibg to worry about carrying a blade.
Brilliant pice of kit
I wasnt so sure in the begining but i fell in love with it , compact , discret and very good quality
I was flabbergasted how this tool fulfills my expectations!
This thing is properly named, but i is extremely well made. Comfortable in the hand or in the pocket. I go through metal detector & my pocket kit goes through an X-Ray Machine & I’ve not had any issues for my first 2 weeks of taking it in to work. I also think this thing could be devastating if employed for other uses.
Multi tool, libation opener, and keychain arbiter of disputes... this does it all.
Awesome tool! This has been the easiest opening bottles has ever been.
This item far exceeded my expectations. It is covert protection in this ever changing world. I like the security it provides by simply having it in my pocket. Would highly recommend to others. Those duties are killer though but that has nothing to do with the maker or retailer.
Must have tool for self defence!
Good fit in the hand . Not sure it’s TSA approved , still good for streets walks.
The pictures dont do this guy any justice, its thick and sturdy. Feels great in the hand, definitely a handy EDC to have on your person.
The big nasty is perfect for someone with bigger fingers compared to the other models , very nice cuts and design, light weight and looks cool as hell !!!!
I started with the npe Ghost and loved it so much that I had to get the edc aswell. After alittle thought I ordered the Big Nasty and she doesn't leave my presence! Top quality and coming from a guy like Greg well it doesn't get anymore American than that!🤙
This tool is crafted as if a piece of fine art, yet lethal. It's weight is surprisingly light and its feel fits perfectly for a large hand. The screwdriver attachment is seamless and useful. Much like other BT products it's worth every penny. Do not hesitate to get one. Cheers!
No expense is spared on this piece. Lightweight, ergonomic and a must have for any man or women worth their salt. BT never disappoints!
