That is one fine piece of a cutting tool you are showing there. The dragonfly may not be the best option when you need a larger blade. It’s power in my opinion is its carry size. It’s so small you can easily carry it anywhere. The best cut is made with the knife you have on you.
K390 is also an excellent choice. And the wharncliffe blade gives the knife power all the way to the tip. Enjoy using your dragonfly.
