Two cutting edges. One fuller. Every line converges at the tip. Meet Lacerta, a folding dagger from Herman Knives. Refining its symmetry was one of the most time-consuming parts of the design. You can see it in the outline of the double-edged blade, the proportions of the handle, and the two short, slightly upswept quillons.
A longitudinal fuller runs down the center of the blade. On either side, closely spaced diagonal grooves mirror each other in a herringbone pattern. Turn the knife in your hand and the light catches one side, then the other. The same pattern carries through to the handle, tying the design together from the base of the handle to the tip of the blade.
The quillons do more than give Lacerta its classic dagger profile. Their shape allows the blade to open as the knife is drawn from a pocket.
Lacerta is Latin for “lizard,” a fitting name for a knife with a predatory silhouette and a finish best seen in motion.
Herman Knives has a taste for bold forms and the patience to refine details that reveal themselves up close. Lacerta brings the precision collectors expect from Herman, along with a streak of irreverence, to the classic dagger.
!!! BOTH EDGES ARE SHARP !!! We can dull one edge upon request. Please include your request in the order notes at checkout or email us after placing your order.

New improved bearing system.
Washers made of M390 powder metallurgy steel further enhance the already exceptional operation of our knives. Every stage of production has been optimized to ensure even greater precision, durability, and, most importantly, the smoothness of our knives.
Washer manufacturing process:
M390 steel is machined in-house on our Swiss-type lathe Citizen Cincom A20, where the bar stock is processed and pre-drilled.
Washer dimensions: Inner diameter 5.05 mm, outer diameter 11.95 mm; (for Bee and Micro Sting models: outer diameter 9.95 mm).
25 mm-long rods undergo vacuum heat treatment to 60 HRC, reducing material stress and minimizing the risk of deeper blade scratches and ceramic ball fractures.
After hardening, washers are machined using EDM (Electro Discharge Machining) on our Mitsubishi MV1200R wire EDM machine, allowing precise inner hole execution.
They are then wire-cut into 0.6 mm-thick slices, and final wire processing minimizes surface roughness.
Final manual lapping, up to a 4000-grit finish, gives the washers an almost mirror-like surface, ensuring even smoother bearing operation.
All these processes are carried out entirely in-house by Herman Knives.

The custom Herman Knives pivot was fully designed and manufactured in our workshop. Built on the TORX T20 system, the construction features a newly developed thread with an increased diameter and reduced pitch, resulting in higher precision and smoother pivot adjustment. This solution minimizes the risk of play and ensures more stable settings.
The component is made of 440C stainless steel, vacuum-hardened to 56–58 HRC. The vacuum hardening process guarantees a uniform steel structure, excellent dimensional stability, and increased wear resistance. Thanks to this, the pivot offers long-lasting durability and retains its properties even under intensive use.
The screws are made of vacuum-hardened stainless steel. All three components are produced in-house by Herman Knives on our Swiss-type automatic lathe.
Bearings with increased stability
Based on years of experience, the new bearings feature a caged design with 16 ceramic balls. Their well-thought-out and tested structure effectively prevents ball displacement while ensuring optimal smoothness of operation.

My name is Bartosz Herman. I produce knives according to my own projects and sometimes on an individual order. I try for every one of my knives to be unique and to enjoy its owner and at the same time to be comfortable and reliable during every day work. I want to develop my skills even further so that results of my work can keep getting better and better. I invite You to watch results of my work
