JHKMKULTRAUHEP: MK Ultra Ultra High-End Production Flipper
Jake Hoback Custom Knives
Jake pulled out all the stops on the Kwaiback MK4 Ultra High-End Production mid-tech. It had all of the exact same features as his custom shop work. The knife rivaled his customs for fit, finish, materials and quality. Experience gained through 12 years of knifemaking guided Jake to put this design in an extremely compact version dubbed the MK Ultra. Everything was thought-out and engineered to make this little beast as strong and reliable as possible. The final product is this amazing quality knife with lightweight everyday carry and your wallet in mind.

The MK Ultra came into being when Jake wanted to make a smaller version of his Kwaiback for his wife's birthday. It turned out to be an amazing little flipper that was tactical yet highly efficient at everyday carry chores. Jakes wanted to bring this knife to market at the most competitive price point possible without sacrificing quality in any way. Thus you have an aluminum handle with a great performing blade made from AEB-L stainless steel. AEB-L was developed for razor blades with a very fine grain structure making it easy to sharpen, while maintaining good edge holding capabilities. It's an upswept trailing point shape that is superbly sharp with excellent jimping on the thumb ramp and an index finger groove providing a precise grip.

The handle is 6061-T6 aluminum with Mil Spec Type III natural hardcoat anodizing. The stainless steel liner lock insert is completely captured by internal 3D machined pockets and the only visible portion is the generous jimping for lock release. This is a superb design that is very easy to manipulate and provides rock solid lockup. The action is smooth and lightning fast thanks to rolling bearing construction with hardened stainless bearing races. It's a mid-tech technically, but it has all the feeling and looks of a full-on custom knife. Proudly made and hand-assembled by Jake in the USA.

Pros: Pocket Clip, Handle Feel, Blade Sharpness, Blade Material, Handle Material, Weight, Ease of Opening, Overall Quality
Cons: Lock Ease of Use, None
Great knife, great size
I can't think of a knife this small that I like better. The lock takes some getting used to but the action and weight make it a perfect EDC. Love the color too.
