- Reviewed in Canada on March 25, 2025Verified PurchaseI may buy a second as a backup.
It is lighter than the KS2E, and the knife is not especially thick for prying anything.
However, the option to change up the knives ,tools and for the city as an EDC is awesome.

- Reviewed in Canada on March 25, 2025Verified PurchaseI have drawers full of different multi-tools. This one is my favorite as you can make a tool that suits your specific needs. The different replaceable tools are of high quality. Not too big to carry in your pocket. This is now my everyday carry (EDC)!
- Reviewed in Canada on May 9, 2025Verified PurchaseThis a very good product from roxon with an easy system for accessories switching. The one's included are great so you don't have to worry about extra items unless you need it (you'll definitely want them even if you don't need 'em lol). Size is perfect. It fits and hold well into a lighter pocket in any pants and the weight isn't an issue. Locking system with extra locking switch is a must. The extra lock switch could have been made of more sustainable material than plastic though. It feels like it won't survive consecutive lock/unlock handling. I bought a lot of roxon products and it is so far one of my favorite. I'll give 4 stars because a perfect tool does not exist and because of the extra plastic locking switch.
- Reviewed in Canada on January 18, 2025Verified PurchaseVery nice tool, the fabrication and assembly are up to par with the other big brands and the mechanism is very smooth and tempting to always fidget with.
The only downside, which I think is a big one considering this is supposed to be a modular tool, is that the implements are limited depending on your location.
If you're outside of the US, you can only buy the implements on 鶹 or Aliexpress, which are only sold in kits of 3 which almost all contain atleast one implement that you already have with the tool. Not all the implements are available in these kits, so I reached out to the sales team on their official site and on Aliexpress to try and buy them separately but so far it's been a hassle. Little to no communication on AlieX and for the sales team on the official site, they've been more responsive, but the purchase process is sketchy where you've got to send money to another address on Paypal and tell them when it's done so that they can ship the parts.
Tldr; Great modularity concept on paper but not so modular in practice. Good buy if you live in the USA, but if you live outside of that you're better off with their KS2E or some other brand equivalent.
Only time will tell if they'll have better coverage and offerings, if so, I'll update my review to reflect it.

- Reviewed in Canada on March 1, 2025Verified PurchaseI wasn't looking to get another multi tool but ended up planning a last minute trip to Mexico. Surpisingly they have more restrictive knife laws than Canada, this is especially so for tourists! I simply left the blade at home and swapped in other tools. This way I didn't have to worry about being potentially searched by police for being a foreigner.
As for the multi tool it's self it is well constructed and the modular options it comes with are handy enough.
One issue I had was being able to deploy a single tool at once, so I just flicked it open to deploy all of them and fold the ones I didn't intend to use back into the handle.
I am looking forward to purchasing some of the other tools for this kit.
- Reviewed in Canada on June 7, 2025Verified PurchaseNot as well thought-out as the Elite, the tools lock is sloppy and there is a noticeable vertical wobble on each tool. This does not affect the functionality but does not provide that satisfactory feel that we associate with quality multitools. Also, the scissors are a joke as well as many other interchangeable implements: they are available but not very useful.
It is going back.
- Reviewed in Canada on March 11, 2025Verified PurchaseLooked like a cool item but received this random junk in a sealed box.

- Reviewed in Canada on June 19, 2025Verified PurchaseIt's a neat little knife. I like that that the bits are interchangeable.
Unfortunately the plastic lock on the handle broke the first week. Seems otherwise well made.

5.0 out of 5 stars Great price to functionality value
Verified PurchaseThis is a great tool for anyone that ever wanted the functionality of a Swiss army knife, but is frustrated that there doesn't seem to be one with the toolset you want. This multi tool can be customized with the tools you want. You can set it up once and forget it. Or you can change the tools on the fly and tailor your tool for the purpose you need that day. This set comes with a good collection of tools to get started with and you can buy additional implements for $5-$7 each or in combo packs available here on 鶹. The best part is the price is very comparable and a bit less than most quality Competitors in the Swiss army style knives market. This is especially impressive since the knife on this multitool is made od D2 tool steel which is very sharp and much more tough than the average Swiss army knife sold in this price range. This is a great little tool that is easily operated with one hand and is adaptive to your needs unlike other multitools and the tools they offer are very well made and well thought out. I'm loving it!

5.0 out of 5 stars Perfect modular system
Verified PurchaseJust great, solid hefty tool, packed with high quality implements. Once the pivot screw is tightened no rattle and no accidental spill of tools. Really amazing concept

5.0 out of 5 stars Good well made, customizable tool.
Verified PurchaseThe locking system and tool implements work well. Quality of the tool is good. Flexibility is what makes it better than most pocket carries. With the Roxon Flex, plier multitool, many different setups can be configured with or without duplication.
