MTech USA Embossed Flower Black and Blue Rainbow Multi-Color Tactical Spring Assisted Knife 4"



The spring assisted knife is quite a remarkable blade. Developed because of laws and municipalities that bar or prevent one from legally owning and/or carrying automatic switchblade knives, it is the perfect solution!

This spring assisted knife, in contrast to a standard automatic switchblade knife, is not opened by pressing an activating button (the button is what gets an automatic knife classified as illegal) , it is opened by using the index-open "flipper", which creates a hand guard when it is open.

The beauty of this spring assisted feat of engineering lies in its pivot area where a wound-up internal spring has been nested that assists in the opening of the knife. It is this spring that differentiates this spring assisted knife from its automatic switchblade / OTF cousins as well as the standard folding, manually-opened, lock blade knife.

To summarize the internal spring featured in this knife assists and finishes the opening process once the index flipper is pushed. That's right!!! Once the blade has reached a 30-40 degree angle, it automatically slams open the rest of the way !!!

The Embossed / 3d Multi Color Flower Moldings on the handle do not tell the entire story of this Beefy knife!  Springing open to an impressive 8.5" with a 3.5" inch Tanto Style Blade while weighing  over 6 oz gives this knife heavy duty feel in the hand with an aggressive stance when opened.  Combined with the Integrated Lanyard Attachment Loop and Glass Breaker this Spring Assisted Knife exhibits all of the Function for a Perfect Everyday Carry that can be used in a multitude of situations.   

The Blade and Frame of this spring assisted knife both feature 440 Stainless Steel Construction and have been finished in Satin Black providing the longevity and durability found in some of the most expensive cutlery . The 3.5" Razor Sharp Tanto Style Blade adds an aggressive undertone to an otherwise colorful knife making it a great EDC everyday carry for somebody who enjoys both a Colorful Overtone with an Aggressive Undertone !

As a legal alternative to a push button automatic knife, an impressive unique knife for your collection, or an incredibly useful tool, perfect for daily use, this Spring Assisted Knife fits the bill!
