Roxon S502U Upgraded Phantasy Folding Pocket Knife, G10 handle Survival Gear Pocket Tool EDC Knife Replaceable Knife Blade with Pocket Clip for Camping Hiking

Has been a very handy knife. Takes down easy and comes back together just as easy. Honestly id recommend this to anyone looking for a simple, basic utilitarian knife with modularity potential.

This is a solid knife. Roxon is onto something here and I hope they don’t greedy like the other big guys. Every single blade I installed which was all 17 of them fit like a glove and the quality of each blade or tool was better than anything I’ve seen in a long time. Make some tech tool attachments or look at the trades and see what each of is using on a daily basis and replicate it in the same way you did this one. Good luck

the handle is pretty nice and the blade is solid. the system as a whole is really cool, lots of functionality with different blades, the multitool blade in particular is my favorite. There are some issues getting the blade unfolded, the handle doesn't offer as much grip as you need, maybe Roxon should use thumbscrews or something instead. I also had the pocket clip bend and break off very easily which is disappointing. overall the idea of interchangeable blades is really cool but leaves some things wanting. looking forward to its improvement.

With hindsight, I feel my original review of this upgraded knife was a little harsh, so I have decided to revise it to be more reasonable. Full disclosure, I have been in touch with Roxon support (directly from China). They explained why they made the changes they did, and although I am still not a fan of losing the single-hand operation, I do understand why they opted and even had to do what they did with the S502U redesign. The knife is very well made. It's also a very handsome knife. The G10 casing is a nice upgrade. I have no way of knowing how the original metal casing felt in comparison, but I can imagine it feels similar (if not the same) to the Roxon S501 scissor/knife combo that I also own. I do actually like the S501 all metal casing, but I would probably like it more if it was G10. All the accessory blades that I purchased for the Roxon S802 fit the S502U well and it is easy and quick to change them out. It is nice to be able to carry around a single blade when it is not feasible/possible to carry around the heavier/bulkier S802. Honestly, I would probably rate this knife 4 stars, deducting one star for losing the single-handed operation. However, I really do appreciate how much Roxon support has reached out and followed up with me, and feel that alone should at least be worth 1 star. You cannot really go wrong with Roxon. I have bought several of their tools/knives/blades, and they are all rather high quality. Add to that excellent customer support and it makes Roxon a brand to be reckoned with in the knife/tool industry.

Very sturdy. No play in the blades, which are easy to swap. Just add a thumb stud for one handed opening and it's perfect.

gave it as a gift to a uncle and he loves it, can switch to safety blade for which then back to whichever blade style he likes for the weekend

From weather emergencies to wrapping gifts, the Roxon S802 has been my go-to for everything since I got it last summer. Adding the S502 lets me use the same excellent blades with less weight -- or more likely carrying both, e.g., with a serrated blade in the S802 and a plain edge on the S502. I do wish that blades could be purchased individually, rather than in pre-selected sets of three, but the sets are really economical and a great value overall, so no points deducted for that. I've been accumulating knives and multi-tools for decades, and have a lot of stuff now that I love, but never carry, not wanting to lose or damage items that would be hard to replace. But my Roxons actually see daily carry -- I just need to buy a few backups for safety, I never want to be without these excellent tools. 👍

I like the look of this knife and I love the innovative idea of swapping blades. I've been using it with the hawk-billed "electrical work" blade for about two weeks. People who complain it can't be opened one-handed; simply pinch the blade with your thumb and forefinger and swing the handle toward you and it swings open with one hand, no problem. And it's razor sharp. Where the design is severely flawed though is in the quick change blades. The two tabs that allow you to disassemble the knife are far too easy to engage and I've taken it out of my pocket half-dismantled multiple times. This is obviously a problem and safety concern. I hope in the future they improve the locking tabs with stronger springs or make the locks curved like on the Roxon Phantom multi-tool. Until then, I can carry this in my pocket in good faith. Will keep it as a bedside tool but that's all I can trust it as for now.

品質保証：２５年間の保証となっていますが、説明書と箱は１０年保証となっています。 また、Ｓ８０２に最適化してあるのか、Ｓ５０２Ｕはワンハンドオープンするのは厳しいです。 サムホールがグリップに半分埋まっているために、指がかかりません。 ワンハンドオープンするには、指の先端（爪）を穴に差し込むか、親指と中指でブレードを左右からつまむか…という感じになります。 また、エクスチェンジブレードシステムは、良くできていますが、クイックチェンジは出来ません。 ２ヶ所ロック解除して、ハンドルを分解して、ブレードを交換して、ハンドルを合わせ、ロックする…んですが、最初はなかなかロックできませんでした。 調整用の工具が付いていたため、微調整を試みるも、さらにダメになってしまいましたが、色々試しているうちにコツが分かり、今では問題なくなりました。 （慣れが必要かもしれません。） 縦ブレは皆無で、横ブレはわずか、といった感じです。 横方向は、ブレード交換のためのクリアランスをとっているので、エクスチェンジブレードできるナイフには、あるものと思っています。 参考までに、以下のナイフでは縦ブレ、横ブレあります。 ケースＸＸチェンジャー バック ４２９Ａ７ アウトドアーズマン セレクター ガーバー ボルトアクション エクスチェンジ これら比べると、ガタつきはかなり少ないです。 ブレードの鋼材の８Ｃｒ１３ＭｏＶ鋼は、日本のＡＵＳ－８ステンレス鋼を参照して中国のステンレス鋼メーカーによって製造されたものです。 ＡＩＳＩ ４４０Ｂおよび４４０Ｃに類似しているとされています。 （６２ＨＲＣ以上に達することができるそうです。） あと、公式サイトの通販からですと、ブレードは１本単位から購入可能のようですので、１本売りされることを期待したいところです。

g10との組み合わせが一番の特徴になるも思う。 手にした感触が心地よい。g10は樹脂だから適度に重さがあるので重厚感もある気がする、、素人の感想だけど。 roxonはflexでモジュラータイプのマルチツールを発表してる。flexはメタルタイプなのでg10との組み合わせたものがそのうちでると思われる。flexが早く日本で入手できればと思う。 s502uとba15の組み合わせで車に載せとく使い方もありかなと、できればガラスクラッシャーをs502uに装備して欲しい
