Behind the code “SC28FP2WK390” is hidden one of the gem designed inhouse by Sal Glesser. The Dragonflies are legion.

Quoting Spyderco: “The Dragonfly 2 is one of the most size-efficient folding knives ever created, especially when expressed with a straight-edged Wharncliffe-style blade. When that blade is crafted from tough, wear-resistant K390 tool steel, the result is a compact, powerhouse cutting tool that will take and hold an exceptional edge.

Like the standard Dragonfly 2, this knife also features a user-friendly back lock, and a reversible deep-pocket wire clip, but its linerless FRN handle is molded in the signature blue color of Spyderco’s K390 family of knives.”

The Dragonflies are very small locking knives which has been made in many many ways: stainless steel handle, Salt rustproof serie and many Sprint Run is now offered in Wharncliffe blade shape with one of the best super tool steel available K390. Such a strong steel on a small thin tool is a must try.
Wharncliffe blades offers such a great performance. I have reviewed it many times.
Backlocks or Lockbacks are known to be the strongest lock available and by design you are chocking the blade by the hum and the choil and you are applying your cutting force directly to it and not to the handle, preserving the mechanism for harder chores.

The handle despite being reduced is for 4 fingers grasp. This is a tour-de-force in term of design.

My Pingo features a thicker blade and, with its slipjoint mechanism, has proven to be a truly reliable everyday companion.

The Dragonfly, on the other hand, offers a more aggressive cutting solution in a more compact package.

The Wharncliffe blade design really excels on the plate: only the tip makes initial contact, which helps preserve the edge from harsh contact with ceramic surfaces. As a result, this small knife can even serve as a very capable, compact steak knife.

As my friend Jur once told me, “The older you get, the smaller the knives you’ll prefer.” Over time, I’ve come to realize just how true that is.

The Dragonfly in K390 is a remarkably refined combination. Ultra-compact, slim in the pocket, yet equipped with a blade that performs far beyond its size, it delivers impressive cutting power and edge retention in a minimalist format.

Lightweight, discreet, and highly capable, it’s the kind of tool that quietly earns its place as a daily companion — equally suited to a lady or a gentleman who appreciates precision and performance in a compact form.
