Why It Matters
From a design perspective, this model executes on a clear philosophy: practicality, portability, and versatility—three pillars that translate directly into field performance.
The foldable architecture achieves a genuine balance between compact storage and functional readiness, while the aviation-grade aluminum alloy chassis delivers corrosion resistance and structural integrity across varied environments. The hawkbill blade is a deliberate choice for outdoor and camping applications, offering optimized cutting geometry for tasks ranging from rope work to detailed carving.
Ergonomics reflect thoughtful execution—the ambidextrous grip accommodates both right and left-handed users without compromise, and the edge geometry prioritizes sustained sharpness for efficient, repeatable cuts. At just 2.5 ounces, the weight-to-capability ratio is notably well-calibrated.
Taken together, this is a tool designed not for novelty, but for reliable service—a practical, user-focused option that performs as intended wherever it’s carried.

Cool Pocket Knife

Been wanting a gravity knife. Have had many otf ¡°out the front¡± knives. And they get dirty and springs always wear out. This has know spring uses gravity and is very made. It comes sharp but I put it on my stone now razor sharp.

Loved this gravity knife
Bogdan –
Everything is good and solid except one thing,the lock on the knife is weak and sometimes just gets unlocked inside my pocket.
Jeannot –
Tanks you woww
TU Nguyen –
Perfect! Just what Iwas looking for. Love it.
Hudson –
The chassis is well built and the engraving looks great. The only reason I give this a 4* is the blade was not cut great. The edge is not straight like a tanto should be. Otherwise the build is great and arrived in a timely manner!
Josh –
This is a really nice knife overall.
– Comfortable and grippy texture on the handle,
– Smooth deployment and retraction.
– Pretty sharp right out of the box.
– Fit and finish are good and can pass for a more expensive knife.
The negatives and why I’m only giving three stars:
The lock is just a sliding button held in place by a slight detent. It might not be an issue in a knife with a “tip upwards” pocket clip, but this one is tip downwards.
As a result, during normal carry with a couple other small items in the same pocket, I discovered that the lock had slid or been pushed open and the blade deployed inside my pocket, after noticing the tip of blade sticking out of a hole sliced in the leg of pants when I sat down.
I stood up and carefully pulled the knife out of the pocket with the blade fully open, and unlocked.
End result is two holes in a pair of new pants, and another knife sitting in a drawer.
My suggestion would be to adjust the lock slider to make it more secure. Some kind spring on the lock keeping it closed unless deliberately activated, a deeper and stronger detent or using a push in, then slide type of lock would also work.
And probably make it a four or five star knife.

I love it, I have zero issues what so ever
Nik –
It’d prettygood
Khalid Bukhash –
The quality and feel have surpassed my expectations, highly recommended.
Larry Yaw –
Super sharp rt out of the box. I did have to rough up the bottom and sides of the sliding safety switch so it wouldn’t open in my pocket. But it’s a great knife and I’ve already hadco-workers and friends ask me where I got it.
Jacko –
good working knife , a bit light i think, but fine knife , good make ..
Timothy Padgett –
Great knife, great quality easy to use highly recommend anybody who¡¯s in the market for a gravity knife. The label was created and it showed no movement for three weeks, but it was due to the package coming in from overseas and then once it hit customs it was delivered in two days.
TU Nguyen –
Nice knife love it
TU Nguyen –
Great EDC

Es una navajabonita y bien hecha. Todo est¨¢ bien ajustado y los materiales son de calidad.
Charles Frizz –
The slide occasionally gets hung up when deploying or retracting due to pocket lent. My major problem is the lock mechanism is easily disengage. If you keep the knife in the pocket with that object, you pull out like your phone. I believe if you indent the lock and add a spring ball bearingthat, that would add just the right amount of resistance to prevent accidental deployment in your pocket
Mike watson –
Great knife i love it
Jaroslav Brus –
I was pleasantly surprised! The price is a bit high for me because of my income, but it¡¯s a nice tool. The quality is good it¡¯s light and was sharp right out of the box. Maybe someday, if I have some extra money, I¡¯ll buy another one for sure!
Hermit –
Amazing, wanted this knife for years and finally found a site to buy this, worth the prize
Jackson Campbell –
Blade came sharp and its fun to play around with, however the handle itself is loose and the blade shakes in the open position. Doesn’t go away by tightening up the screws, defects in th way the metal was cut so it does not fit together properly.
Thomo –
Feels like a quality product. Arrived quickly. Is as pictured and described. I carry it everyday at work. Works well .
Dante Alexander –
Had to tighten some of the hardware on the handle.

Store manager Florian Mielke –
Great knife no complaints im really pleased
Dillon –
Quality wasn’t great. I am glad I got it on a seasonal discount because full price is absurd so though I felt I over paid, it could have been worse. It’s a gimmicky design which is fine if its still useful but it showed up pretty dull and the locking mechnism doesn’t give me a lot of confidence that it won’t wear away quickly if used regularly. After only a handful of times locking and unlocking the friction points already wore away the paint so likely won’t hold long term. Shipping info was bad, it sat with a label created for a week before it actually got packaged. Reached out to customer service received OK support but didnt actually give me much confidence it was really on the way or when I would actually recieve it. They just bought more time until it eventually showed up. I won’t give it 1 star because it is a knife and it does look like the pictures, the gravity function is cool its just not a great product for the money and experience so 2.5 stars rounded down.
Jack Jackson –
It¡¯s neat.
Marco van Hurne –

I love the design of the knife
Micah Kearns –
Intriguing concept and does function as advertised, however the quality seems limited for the price. Blade will wiggle when out and locked. Feels more like a figet toy/conversation piece
