I love this money clip. Its strong and durable and has a jeep grill on the back side. Use it to hold an id and credit card when on the trails and want to travel light. (Cards and money stay in place)
Got it from KickStarter and now become my daily writing instrument. great built quality for writing and as survival tools. Aluminium Black with MG-Core fire starter (just in case i needed to start a fire, although unlikely since i can use the lighter, but hey it's still cool)
Except no imitations, this is the coolest and most badass pen ever! The bolt action is smooth and well engineered and the wistle works well. I haven’t tried out the glass breaker but it looks like it would certainly get the job done. The pen itself writes really smooth and has a nice weight to it and feels really solid in your hand. I bought myself two and now am going to get more for birthdays and xmas gifts this year. My kids kept “borrowing” mine, so I got them their own too. Great product at a great price!
Love the pen, it's lightweight with a solid feel. I haven't tried the glass breaker yet, but the whistle works well. Bolt action is smooth, and fun to play with. I carry in my pocket with no leaks, use the pen for sketching and daily use.. and the ink works well, which is a nice bonus. I would recommend to other designers for sketching if you like the feel of a larger barrel pen.
I like the unibody design and the bolt action is extremly smooth and fun to play with. It comes with a built in whistle which i treied and loved. I tested the glass breaker and it is hard enough to scratch glass. I got the kurled black aluminum version and it feels great to write with. I would reccomend to anyone looking for a high quality pen.
The GP 1945 pen has a solid mechanical feel and minimalist design that appeals to the engineer in me, but I can see it being appreciated by anyone who enjoy well-built products that give you tactile enjoyment. The weight of it feels nice in your hand, and the bolt-action actuator is a pleasure to flick back and forth. The extra features like the whistle and window-breaker adds to the interest, evidenced by the reaction I got from my teenage kids. Oh, and the pen itself is very nice too - smooth and easy to write with. I received one as a gift and then bought one to give to a friend. Sure, you may not normally buy a pen for this price, but it's not just any other pen - it's a well-crafted object to enjoy spending time with.
This is a very well made pen. I’ve been carrying it for about 2 weeks now and I really like it. Other tactical pens try and cram way to many features into a design, but this one really hits a good balance. It does everything they say that it does. I work construction, so anything I carry every day lives a hard life! So far there isn’t a scratch on the thing, looks brand new! If you’re looking for quality in a sleek design then this is the pen for you.
This is an awesome pen that I always carry in my car now. There's always a need for a reliable pen in your car, and this one can break a window in case you're trapped. Also, the whistle is nice to have just in case. The action is really fun to fidget with and the construction is strong enough to where I don't believe it'll ever break under normal use.

I have been using the GPCA wallet for two years. I was a little skeptical originally about the all metal construction for a wallet. My skepticism was mostly centered around how many cards it can hold given it\'s low and un-expandable volume. After two years of daily use, I found the silicone band could easily hold 6 cards stacked on one side without any issues. There\'s a display card on the other side for an ID. So I have a total of 7 cards, more than enough as an EDC item. The silicone band hasn\'t shown any wear and tear yet. It still holds the cards snug. I was also surprised to find how useful the lanyard clip is. I could clip in my house keys and clip to my belt loop or any other bags and accessories. It\'s convenient all around.
FAQ
What is the GPCA™ Carabiner PRO X KEY?
The flagship GPCA everyday-carry multi-tool carabiner: a screw-gate carabiner with a box cutter, Safe Dull Cutter, pry tool, bottle opener, Phillips and flathead drivers, a ruler, the Added Key Zone and a Secret Capsule, plus an integrated key module that holds up to 3 keys silently inside the frame. Available in 420 steel or Grade 5 Titanium.
PRO X or PRO X KEY: what's the difference?
Both are on this page and share the same frame, tools and ruler (all Carabiner PRO functions plus the ruler). The PRO X KEY comes with the integrated key module for up to 3 keys. The PRO X is the same carabiner without the key module; you can add the Key Module Addon to it later.
Which tools are built in?
Box cutter (removable blade module), Safe Dull Cutter, pry tool, bottle opener, Phillips driver, flathead driver and a ruler, plus the Added Key Zone, an independent keychain hole and the Secret Capsule in the gate. There is no hex wrench on any GPCA carabiner. A Torx T6 + T8 service tool is included.
How does the key module work?
Load your keys onto the module with the included spacers between them; it holds up to 3 keys silently inside the frame. If the keys feel loose, add the included rubber washer next to the spring for more compression, and use a little low-strength Loctite on the screw once the tension is right. The T8 bit adjusts the module.
What materials and finishes are available?
420 steel, polished with a light brush on both sides; or Grade 5 Titanium with a matte, dark metallic satin finish. On the titanium edition almost all tool modules are titanium too; only the small screws and the Phillips bit are steel. The PRO X KEY weighs about 4.43 oz in steel and about 2.8 oz in titanium; the PRO X about 3.75 oz in steel and about 2.4 oz in titanium.
How much weight is it rated for?
200 lb static for both steel and titanium. It is an everyday-carry tool, not rated for climbing, rappelling or fall arrest.
Is it TSA-compliant?
Yes, for U.S. carry-on after you remove the box cutter module with the included Torx T8 tool. Pack the blade in checked luggage and carry the frame. TSA rules apply in the U.S. only; some countries, such as Australia, are stricter, so check before you fly.
What is the Secret Capsule?
A hidden compartment in the gate. Open the gate inward and unscrew the knurled ring all the way off the threaded post to reveal it. It fits a small flint, a rolled bill, 1–2 pills or a spare T8 bit. Screw the ring back on to seal it.
How big is it, and can I use it as a handle?
About 4.13 in × 2.1 in × 0.6 in (105 × 53 × 15 mm). The opening is about 3.1 in (80 mm) wide, so most adults get a full four-finger grip to carry bags or use it as a grab point.
What are the Red Ring and Red Tag add-ons?
Red Ring: an aluminum accent ring that replaces the stock gate ring; Red Ring editions include both rings. Red Tag: the GPCA Adventure Red Key Tag. Spare parts: cutter and screwdriver parts and the Torx 6 + Torx 8 tool.
What does it clip to in the GPCA lineup?
It clips into the GP-Grip handle utility loop, the Dog Leash X-Clip and the United-1 Wallet clip-in point.
How does it compare with the PRO, LITE and X Grip?
Carabiner PRO: the same tools without the key module or ruler. Carabiner LITE: single-piece unibody with box cutter and bottle opener, no drivers. X Grip: oversized 5 in frame with a grip zone and bottle opener, no blade or drivers, TSA-ready out of the box. A Key Module Addon fits the PRO X, PRO and LITE (not the X Grip).
What warranty does it have?
Lifetime warranty.
