Herman Knives Sting Flipper with Tumbled M390 Blade, Tumbled Titanium, and Fat Carbon Inlay

The Herman Knives Sting Flipper is a premium custom folder that blends modern machining, refined materials, and the precise mechanical feel that has made Bartosz Herman’s work so respected among collectors. This example features a tumbled M390 drop point blade, a milled and tumbled titanium frame, a fat carbon inlay, and a carbon fiber backspacer, creating a clean, high-end presentation with strong everyday carry appeal. Offered in excellent preowned condition and sourced from a collection, this knife shows no blemishes, marks, or signs of carry.

At 3.375 inches of blade length, 7.875 inches overall, 4.5 inches closed, and 3.6 ounces, the Sting sits in a sweet spot for collectors who want a premium custom flipper that feels substantial without becoming bulky. The proportions make it practical for real carry, while the materials and execution keep it firmly in collector-grade territory.

Precision Build with Titanium, Fat Carbon, and M390

The blade is made from Böhler M390, a premium stainless steel long favored in the knife world for its combination of corrosion resistance, edge retention, and overall performance. Here, the tumbled finish gives the blade a more understated, working look that fits the Sting platform well. The drop point profile keeps the knife versatile and usable, while the flipper action adds the crisp deployment custom knife buyers expect in a modern titanium folder.

The handle is built around a milled and tumbled titanium frame with a fat carbon inlay, giving the knife both strength and visual contrast. Herman knives are especially appreciated for their machining and tactile finish work, and that comes through clearly in a build like this. The titanium liner, tip-up clip, and carbon fiber backspacer round out the package with materials that feel premium, cohesive, and purpose-driven.

This Sting also benefits from the action details collectors care about most. It has a nice detent, solid lockup, and proper blade seating, and it rides on bearings for the smooth deployment that Herman Knives is known for. For buyers looking for a refined flipper with strong mechanics, that matters just as much as the material list.

Herman Knives, Bartosz Herman, and the Sting Model

Bartosz Herman is a custom knifemaker based in Łódź, Poland, known for building high-end folding knives that combine utility, precision, and artistic presentation. His work is often associated with premium steels like M390 and Elmax, titanium frame construction, distinctive milling, and highly tuned bearing systems. Herman Knives also developed the Herman Ceramic Rotary Locking System and is widely recognized for pursuing mechanical refinement as seriously as visual design.

The Sting is one of Herman’s notable models and has become popular with collectors who want a compact, elegant, but still performance-oriented folder. The model is often described as lightweight, compact, and versatile enough to move comfortably between everyday carry and dressier use. That versatility is a large part of the Sting’s appeal, especially when paired with premium materials like fat carbon and titanium.

Because this example includes the original zippered case but does not include the COA, it should be presented clearly for buyer confidence. The condition remains a major selling point, however, and for a preowned piece sourced from a collection, this Sting represents a strong opportunity for collectors seeking a clean Herman Knives example with excellent materials and mechanics.
