The problem was how to prevent the point of the pen from stinging your arm. The sheath solved that problem by elevating the pen away from the skin and encasing it so that the point of the pen is sheltered.

I bought both the knife and the pen, along with sheaths. It’s very nice having these essentials everyday tools right on my watch whenever I need them. I can’t count how many times I needed one of these and didn’t have them.

Received mine in 16mm Watch Strap meant for my CASIO-LWS2200H. The sheath fits initially tight, but slots in nicely past the initial strap entrance and doesn't budge an inch except with great pressure, making it impossible for it to become loose as it'll also be locked in by the watch's buckle.

The EDCest pen itself comes with five extra refills apart from the one already inside the SLS plastic. It is pretty fun to use, as I'm used to writing with some of the tiniest stationery in the market (Ohto Minimo Pens and Pencils) , but this one is even smaller than those! It takes some getting used to, being such an incredibly tiny little pen, but I can write quick jotting on my notepad as well as signing documents competently with them, and being on my watch that I wear on my wrist 24/7 makes it a very easy access, a sublime experience that feels good to use, and a nice conversation starter with my co-workers and clients! Replacing my ink with a wide variety of multipen refills (Uni Style Fit Ballpoint and Gel Pen refills are some of the best in the business) is also nice and effortless! I use the Ohto Minimo Mechanical Pencils primarily, but as I need a pen for signing and quick jots, this definitely is an essential partner for my watch. Black-on-black makes it look sleek as well!

Thanks, Ultimatest! I really love these. Might get a bunch more pens and sheaths from you for future-proofing. May you continue to bring us novel wristwatch tools!

So I first saw this product back in 2021 on Knife news. Figured it looked fun and supported it. From January of 22 until January of 2024 it rode on my wrist every single day. The usability is second to none. After two years I somehow lost it, emphasis on making it two years with daily workouts, showers, and day to day life.

I looked for about an hour and immediately bought a new one. The new black sheath and coated blade blend in far better than the old and the new sheath has improved retention. I can't recommend it enough.

THE EDCEST EDC KNIFE - KNIFE ONLY

This product fulfills its vision to a tee. It's the most useful EDC gadget I've ever bought, because it transcends every *day* carry and becomes every *moment* carry. It's come in handy so many times ever since I put it on my watch that I've lost count. It's to the point where, again like no other gadget I've ever used, it feels like a natural extension of the self. It's also remarkably ergonomic to actually use for cutting things. I would give 6 stars if I could, and I'm 100% buying the pen once that becomes available again too. I'm incredibly excited for what's next for the Ultimatest.

One question, though, while I'm here: are custom-colored sheaths still available after the whole Shapeways situation happened?

So convenient, have bought 2 of these including the new pen.
Fantastic idea. Always get questions regarding the little gadgets I have on my watch strap. Looking forward to the next innovation from this company.

This is not the first time I buy from Ultimatest and certainly won’t be the last. This tiny gadgets made great gifts for anyone.

The EDCest knife is always just a reach away for all those small odd jobs you invariably encounter in the office or in the field, whether it's opening a package or measuring a small handheld item. It gets the job done!

Love this watch strap knive

I'm always looking for a small blade, to cut a thread, open a box, scratch a lucky card... and no matter how many small knives I buy, I always forget to take them with me whether it's at home or at work.
With your product, the blade is always on me, I don't take the watch off my hand, so the heart is always within reach.
It is sharp, strong and does not take up space or weight.

magnificent.

I needed a extra knife and pen holder so I reached out to Ultimatest and they without hesitation sold me exactly what I needed and shipped it express mail. I'm very happy with the product and service they offer.

Honestly I use this knife on my watch literally once a day if not more. This could be the greatest EDC item ever conceived or built especially the magna cut version. I haven't had to sharpen it once.

I lost my first EDC Knife i ordered a long time ago. Couldn't live without it and had to order another. Great product!

Good marketing, creative concept
