My Review of the D6TC UPknife: A Perfect Tiered Defense Tool
I want to express how impressed I am with the D6TC UPknife. It is, without a doubt, one of the most thoughtfully designed self-defense tools I've encountered, earning a solid 8/10 from me.
What I Absolutely Appreciate
My appreciation for the D6TC centers on its tiered utility, strength, and how perfectly it aligns with my personal self-defense philosophy.
Versatile Utility, Closed and Open
* Closed-Position Power: The D6TC truly excels as a force amplifier, working effectively even when closed. I value its substantial impact capabilities when closed, which allows me to impose shocking pain on an assailant without escalating the situation.
* Superior Ring Impact: Specifically, the ring has impact capabilities that, in my opinion, far exceed any current self-defense tool when the knife is closed.
* Tiered Options When Open: When deployed, the knife offers more than just impact. It gives me the option to penetrate and slice, showcasing its maximum utility. This gives me a full range of options for moments of chaos.
Strength and Philosophy
* Robust Construction: The use of 7075-T6 material ensures that the tool maintains its strength under duress, which is crucial for reliability.
* Ethical Defense: This is the most important feature to me. The D6TC offers me tiers and options to protect my life without needing to end an attacker's. In my personal philosophy, killing should be the absolute last resort in any self-defense scenario, and this tool is perfectly designed to give me the options to enforce that.
The Minor Modifications I Would Suggest:
While the product is excellent, I do have a couple of suggestions that would make it even better. These are not flaws in the design, but simple refinements:
* Pocket Clip Stealth: I would love to see the shine on the pocket clip dimmed. Perhaps an oxidation process or some type of special touch to remove the high-gloss would make it more incognito. This would allow it to better blend in with my pants or other clothing and keep it less noticeable.
* Mirrored Version: I would also strongly recommend offering a mirrored version of the product to accommodate users who prefer or require a left-handed orientation.
Conclusion: A Perfect Base to Grow From
Overall, I give the D6TC UPknife an 8/10. It’s not just a tool; it’s a commitment to controlled, necessary force. The D6TC is a powerful and versatile piece of gear that performs perfectly right out of the box.
The suggested changes are merely minor aesthetic and accessibility tweaks that would take an already phenomenal product and make it virtually flawless. It is a fantastic foundation that provides every option I need to protect myself and my loved ones.

10/10 can’t recommend more. Do have a few tweaks I’d recommend. Feels really light in the hand and the blade could be longer are my only complaints

amazing quality. very practical but also visually appealing. I showed to to a bunch of friends and they loved it. it’s very unique and nothing else like it on the market. I will definitely be buying more knives.

I did not expect the blade to have such refined quality. Lightweight strong and retractable. I’ve already tried to abuse and break it and it seems to be holding up very well. The blade is self sheathing and is not good for cutting really only piercing.

10/10 would recommend

Great product, quality make and materials, great communications, quick shipping, I highly recommend!

A few years ago I discovered a page on instagram with a man with a Passion for Kinife making. After years of following Johns page I finally ordered something I had wanted for so Long the UPK- M2lite. I was in awe when my parcel arrived and couldn’t believe I finally had my hands on one. The craftsmanship and detail that has went into this product is unbelievable. He guided me on the design and found the time to send me videos and pictures of the finished article. An expierience like no other. Delivery was fast transiting to Scotland way quicker than it should have. Great experience outstanding product. Big thanks to John f for his help and expertise to make my product so unique. I’ll visit again in future!!!

It’s been a while since I saw something I had to have, but the price didn’t make it easy. Happy to report that the quality met my high expectations. Not to mention it shipped quickly, was easy to install and looks cool as hell. #HappyCustomer

i’ve been a knife collector for a while. always looking for new creative tools. UPKnife has it. This model is compact and ready for use whenever needed. Very satisfied.

I recently purchased the upk- d40 eclipse talon m-LOK I seriously love it. Super cool super lightweight very efficient easy to mount. For as light as it is it's super sturdy. Everyone that has seen it loves it. Planning on buying another one as a gift for my son
