I love this knife

I love this knife. Very easy and safe to change the blades. Love the 3.5 inch blade. Very well made and very comfortable handle. Everyone should own one of these knives. I have 5 of there knives and about to buy another one today.

Thanks, Tim! We love the enthusiasm and appreciate your ongoing support!

Good option

Good option to keep a sharp edge without time wasted sharpening

I really like the feel of the grip of the handle in my hand

I really like the feel of the grip of the handle in my hand. It is very comfortable and easy to use with no slipping. I purchased a Razor VX Advanced Carry and it was more money. However, after receiving the knife I found out that I don't care or like the grip of the handle. Even though the handle has some slots cut into it, it is not easy to control or operate. The Razor VX Advanced Carry needs some more thought given to the handle. As for now, it remains in my drawer, and I carry my new 3.5" ONYX EDC.

very light and easy to open and close

very light and easy to open and close . didn't try to remove blade yet but it looks easy.

OUTSTANDING

So glad I bought this knife and blades! One of the best!

I carry this all the time

I carry this all the time. I have 4, and they are used more so than my usual EDC knives. Great quality and the ability to change out blades when needed. These knives are NO. 1 in my book.
