Tac-Force Black and Gray Spring Assisted Tanto / Etched Blade EDC Knife w Polymer Scales 3.5"



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 !!!

Springing open to 8.5" ( 3.5 inch Blade ) ,and weighing only 1/4 (4.8 oz) lb due to its weight saving ABS polymer scales means this Spring Assisted Knife exhibits all of the function for a perfect everyday carry.  The matte black 440 atainless steel gray cross hatch etched tanto style blade make it highly resistant to the elements while offering an aggressive look.

Add to all this, a handy / removable pocket clip / spine and blade jimping for enhanced grip / as well as a lanyard attachment hole and you have a knife that is conveniently suited to most tasks.

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 Stiletto Spring Assisted Knife fits the bill!
