UltiClip Slim 3.3

5 stars, but 2 things first. 1, the seller should ship with a better speed. USPS bounced my package around the state twice and I got it 2 weeks after ordering. Both the seller and USPS fault. 2, I knew 10x retention, but it took a bit to get used to how hard the clip was to open and close so it's not too easy to install and use, but the positive here is it isn't going anywhere. Just make sure you don't have long or weak nails Now the good, I love how slim it is and how great it works. It holds tightly to my pocket or inner waistband/belt and is so slim that the fit for my knife is so low profile I can't even see or feel I'm wearing it. I tested against several of my kydex sheaths and it fits everything good except cold steel secure-ex sheaths which just have a slightly different eye pattern on them. This thing looks like it's built to last and I'm extremely satisfied with it overall.

TLDR; The UltiClip Slim 3.3 is the ultimate solution for deep, secure, and belt-less concealed carry of your fixed blade. Its narrow, low-profile design and powerful clip retention make drawing the Boker Tracker smooth while ensuring the sheath stays locked in place. I bought the UltiClip Slim 3.3 specifically to upgrade the carry potential of my Boker Tracker. The Tracker, being a robust and substantial fixed blade, comes with a Kydex sheath that, while functional, benefits greatly from a custom-style carry clip. The goal was deep concealment, rock-solid retention, and the ability to carry without a dedicated belt, which a standard belt loop or large Tek-Lok doesn't easily allow. The Slim 3.3 is an absolute game-changer for fixed-blade EDC. Its core design—a highly secure, spring-steel clamp—allows it to lock onto the hem of a pocket, waistband, or even athletic shorts with incredible force, far surpassing the simple tension of a standard clip. This is crucial for a knife like the Boker Tracker; the clip retains the sheath so firmly that when you draw the knife, the sheath stays anchored, allowing for a clean, fast deployment. The 3.3-inch length is ideal for this size of fixed blade, providing a good mounting base on the sheath. Crucially, the clip is only 0.60 inches wide, making it perfect for the narrow profile of the Tracker's sheath and ensuring minimum "printing" or bulk for maximum concealment. It’s built from heat-treated C-1075 Spring Steel with a military-grade black oxide finish, meaning it can handle the weight and abrasive environment of daily carry without issue. The dual slotted mounting area allows for 1.5 inch hole spacing, which usually aligns perfectly with the common eyelet spacing on quality Kydex sheaths, making installation straightforward. The Slim 3.3 essentially turns the Boker Tracker into an exceptionally discrete and reliable deep-carry fixed blade. Pros and Cons Pros Maximum Retention: Patented clip design locks onto fabric for secure, immovable retention during the draw. Belt-Less Carry: Allows secure carry on waistbands, shorts, or pockets without a traditional belt. Minimalist Profile: Extremely narrow (0.60 inch) design is ideal for deep concealment on fixed blade sheaths. Durable Construction: Made from heat-treated C-1075 Spring Steel with a military-grade black oxide finish. Cons Clip is very tight initially and can be a little difficult to open until broken in. May require modification (drilling) of the sheath if eyelet spacing does not match the 1.5-inch slots. Can't clamp onto material thicker than about 0.12 inches (approx. 4 layers of denim). Verdict The UltiClip Slim 3.3 is a five-star upgrade and a near-perfect accessory for the Boker Tracker. If you are looking to carry the Tracker, or any fixed blade, with the utmost concealment, security, and versatility, this clip is a must-have. It is best for anyone demanding deep pocket carry or belt-less concealed carry, transforming a great field knife into a discreet and quickly accessible EDC tool.

I absolutely love it. It was a little tight to open, but after that it's great. I use the clip to hold my edc knife in my riding vest and was worried about my knife getting loose and falling out at highway speed becauseof the wind. This clip holds it rock solid to my vest and to the sheath.

Nothing is wrong with the clip it is very sturdy and definitely grips on extremely well. It didn’t quite do what I wanted to do with it but that is not the clips fault. I would recommend to anyone looking for a little tough clip.

Works fantastically for an edc fixed blade. No complaints, whatsoever. It was easy to install, low profile and comfortable. Does exactly what it was designed to do.
