Detailed product description
Benchmade Auto Fact 4170BK is an exceptionally interesting model that differs from ordinary folding knives not only in its appearance, but above all in the design of its opening mechanism. It is based on the popular Fact model line, whose characteristic feature is a long, slim silhouette inspired by classic elegant Stiletto-type knives.
The 4170BK version brings automatic opening, which significantly changes the way the knife is handled. The construction combines traditional elegance with modern technical solutions from Benchmade.
Spear Point blade
The dominant feature of the knife is a long, slim blade with a Spear Point profile. This shape is characterized by symmetrical geometry and a strongly defined tip that follows the blade axis.
The Spear Point profile offers an interesting combination of precision, control, and versatile usability. Thanks to its slim shaping, the blade is suitable for more precise cutting tasks, opening packages, and everyday work.
The pronounced tip allows precise cutting control, but due to its geometry it requires sensible handling. It is not intended for prying or lateral stress.
The black DLC finish gives the blade a luxurious, understated appearance and reduces unwanted reflections. At the same time, it helps protect the surface from ordinary wear.
AXIS Lock automatic mechanism
The most interesting construction feature of the Auto Fact 4170BK is the automatic AXIS Lock mechanism.
Unlike conventional automatic knives that use a classic button on the handle, Benchmade uses its own construction solution based on the AXIS mechanism. The control element allows the spring mechanism to be activated and the blade to be released automatically into the open position.
The design also includes a safety lock that helps prevent unintended activation while carrying.
This solution offers an interesting alternative to classic button-activated automatics. It preserves Benchmade's characteristic way of operation and delivers a different user experience.
Handle and ergonomics
The handle of the 4170BK is designed in the spirit of the overall slim construction. It combines elegant metal parts with decorative and functional elements that underline the premium character of the knife.
The shaping respects the elongated silhouette of the Fact model line. As a result, the knife looks very elegant and does not take up as much space when carried as its overall appearance might suggest.
A notable detail is the carbon fiber inlays, which create an interesting contrast with the dark construction. The result is a combination of technical and representative appearance.
Everyday carry and practical use
Although the Auto Fact looks very elegant, it is not just a design or collector's item. Its construction also allows for everyday use.
The slim profile and well-designed pocket clip allow comfortable pocket carry. The long blade offers enough working area for ordinary cutting tasks.
Automatic opening will be appreciated especially by users who prefer a specific style of handling and quick readiness for use.
However, the Auto Fact should be seen primarily as an elegant, precise folding tool rather than a heavy-duty work knife intended for rough handling.
Character and philosophy
Benchmade Auto Fact 4170BK is a demonstration of how classical knife elegance can be combined with modern construction technology.
Its appearance refers to traditional slim Stiletto-type knives, which have always been associated with a long blade, elegant lines, and a minimalist concept. Benchmade brings this concept into the present and complements it with its own automatic mechanism and modern construction elements.
The result is not an ordinary automatic knife. Auto Fact has a distinctive character that will appeal especially to customers with an eye for design, quality mechanics, and precise craftsmanship.
It is a model that catches the eye at first glance and whose true value lies in its thoughtfully engineered details.

Possible limitations
Benchmade Auto Fact 4170BK is a specifically focused model that may not suit every user.
Its slim construction and elegant profile prioritize precision and comfortable carry over robustness. It is not intended for prying, chopping, or other forceful tasks that could damage the blade or mechanism.
The long and distinctly shaped blade requires enough space and care when handling. The automatic mechanism is also more mechanically complex than standard manual opening and requires regular maintenance.
Another aspect is the purchase price, which corresponds to the model's premium positioning and the construction solutions used.
Maintenance and care
After each use, clean the knife and dry it thoroughly. Pay attention not only to the blade, but also to the handle, the area around the AXIS Lock mechanism, and all moving parts.
The automatic mechanism needs to be kept clean. Dust, fine debris, and dried residue can negatively affect its proper function. Use suitable cleaning products and avoid excessive amounts of lubricant.
Inspect the blade regularly and, if needed, treat it with a thin layer of suitable protective oil. Even with a quality surface finish, the knife should not be exposed to long-term moisture.
Do not disassemble the automatic mechanism without the proper experience. An improper intervention may negatively affect its function and safety.
Check the edge regularly and, when needed, restore it carefully while maintaining the correct sharpening angle.
For regular maintenance, we recommend the Spyderco Tri-Angle Sharpmaker Complete Sharpening System 204MF, available on our Moskito.cz website. It is ideal even for plain edges and allows convenient routine care of the cutting edge.
Store the knife in a dry place and protect it from prolonged exposure to moisture.
