This high-powered stiletto spring assisted knife mixes style with tactical ability. Built for self-defense, this piece is equipped with Tailwind spring assist technology for lightening fast blade deployment. The assisted-open mechanism is activated by pressing the blade spur on the back of the blade.

The blade is forged from 7CR13 stainless steel, comes sharp from the factory, and is finished in black. The handle has a futuristic design with bio-hazard artwork, and provides a secure grip even when wet. The handle also features a belt clip for easy carry. 3 3/4 in. blade, 8 1/4 in. overall.

How are Spring Assist different from a Gravity Knife or Switchblade Knife?

Gravity or Switch Blade knives feature a button, level, or other type of switch that releases a spring pressure to automatically open the blade. On a Spring Assist knife, there is no separate button or switch. Instead, you apply pressure to part of the blade to begin the opening process. This is usually a small bump of metal which sticks out under the knife, making it fast and comfortable to use. Once you press on that part of the blade, it automatically opens and locks into place. Since the action of opening the knife is started by pressing the blade metal, instead of a button or switch, it is considered to bypass the laws which ban Switch Blade knives.

This is a very quick opening, and dependable knife. I carry it always, and recommend it highly. An easy to carry back up knife "Just in case".

very impressed

Very impressed with this knife. I did not expect the knife to be this good for about 20 dollars. Very slick design just like in the picture. Opens very smoothly and quickly.

the knife is rugged and safe that you can run, jump, crawl even swim with it (remember to clean and lubricate it after wards). Sharp as heck and easy to open. For the price awesome value.

Awesome Knife!!

This knife is the best for the price. It has a very slim profile and extremely fast opening. Budk is worth ordering from if you can get 20% off or free shipping. The knife looks great and is very durable! I would order another one if this one goes out. Very sharp as well, cuts cardboard like paper! Definately would recommend to everyone. I love UC!

Can't Beat It For The $

Very slick knife. Hard to believe that I was able to purchase several during a sale.....you'll never beat the price for this quality. This knife is sturdy and secure. Will take a tremendous edge, though it was sharp out of the box. Watch for those sales guys. BUDK can NOT be topped....not by anyone.
