Hunting knives

RUBIG’s manufacturing technology enables also the manufacturing of knives. The forging of the knife blade takes place by means of in-house drop forging, while the grinding of the blade is performed by a knife-maker by hand.

Producing knives has traditionally been closely connected with forging. Having manufactured blade blanks for knifemakers to craft hunting knives and swords, we at RUBIG began to develop our own knife designs. We utilize existing in-house facilities and our excellent level of know-how to forge, process and heat-treat knife blades. The craftwork and leather sheaths are produced in cooperation with Slovak knifemaker Ľuboš Píš.

RUBIG knives are available in a variety of designs, from forged or machined blanks to finished products.

RUBIG offers ready-made hunting knives – upon request with engraving or monogram, but also as a knife blank in the series Helios and Genius. The knives are not made in large-scale production, but only in small batches – so they remain exclusive and valuable. RUBIG knives are highly stable due to the flat-blade or the largely dimensioned screws. Damascus knives are frequently made to order.


Our “Helios” model is a classic integral hunting knife. The shape of the handle – facilitated by the drop-forged blade – feels very comfortable in your hand. The wide and well-rounded contact surface for your index finger ensures the highest level of safety and allows for high-strength applications. We would also like to point out the extreme rigidity of the blade, the center of which (i.e. the area with the highest load) has the largest diameter with a generous blade transition radius. The handle design allows the knife to be used safely and comfortably, even with the blade rotated to the side or upwards.

Already at the initial design presentation stage, the prototypes were awarded “Knife of the Year 2013”.


Our “Genius” knife is another hunting knife. While the blade is also drop-forged (just like the Helios model), the handle is attached to a massive screw-shank, which is just as robust as a single-piece forged design. This design supports a variety of different handle variants. The original design includes turned handles made of stabilized woods or horn with a number of different end cap or knob versions. The design options, however, are much more diverse and allow our customers to craft their very own customized knife.

Individual pieces

When developing new knife designs, we end up manufacturing small quantities of custom product. While not all of these knives are drop-forged, they are still rare collectibles of high quality. For those who are looking for a design that stands out from the large number of knives available, in particular collectors of special-edition knives, these pieces with their at times exotic-looking designs may offer great appeal.

Many enthusiasts of beautiful knives buy a knife blank in order to have themselves a “Knicker” made, or a special gift for themselves or a jubilarian – in most cases, for a well-deserved huntsman, hunter, hunting instructor, member of a hunting consortium, etc. (and some hunter may say thanks in this context for a longed shot). Whether the handle is then made of deer antler, stabilised wood, an exotic species of wood, such as Zebrano, Cocobolo... or carbon fibre, is an irrelevant fact in most cases.

Safe2edge Knife sharpener

The knife sharpener from RUBIG

In order to perfectly sharpen a knife, you will need a good cutting edge angle. Depending on the knife application, this angle will vary between 25° and 35°, and the ideal angle for different applications depends on the experience and the preference of the user. There is already a wide range of sharpeners available which vary greatly in price. But they do not always meet customer requirements. This is why we developed the RUBIG Safe2edge knife sharpener.


In its operation it is similar to an Edge Pro system, but it features the following improvements:

  • Tool-free operation: no need to use the Allen key near the knife edge, which ensures a safer operation
  • The knife is clamped into the device for sharpening: no need to hold the knife during sharpening, which means right-handed users do not need to sharpen with their left, and left-handed users do not need to sharpen with their right
  • Tiltable and height-adjustable support: prevents the knife from wobbling or slipping
  • Angle- (and depth-) adjustable stop: for the angular alignment of the sharpening stone in relation to the knife edge to ensure the most even sharpening angle right up to the tip of the blade
  • Supports with protective coating: prevents scratching the surface of polished knives
  • Extended sharpening element: to sharpen long-bladed knives and for optimum use of the length of the sharpening stone
  • Steel design: durable, robust, resistant to oil

Anglers’ accessories

We use STEEL, not LEAD, for environmental reasons

In many areas of daily life we attempt to remove harmful substances from our environment.

In the 1950s and 1960s a large number of domestic water pipes were made of lead, but these have now been replaced. Until the early 1990s, it was common to use toxic lead compounds as fuel additives, which is unthinkable now.

While only a few years ago lead played an integral role, for example, in balancing tires and in joining technology, more and more environmentally-friendly substances are now used for the good of the environment.

Hunters have also made changes. Heavily soil-contaminating lead ammunition has been replaced by tombac and soft iron.


It is time to provide alternatives for modern, environmentally-conscious recreational anglers!

And a good option that takes account of environmental considerations are anglers’ accessories made of steel.

Steel offers many advantages, including:

  • Steel is made from naturally occurring elements.
  • Steel is a standardized material.
  • Steel can be used with a clear conscience.
  • Steel has a high hardness that creates sound and ensures a special fishing experience.


And steel comes from the heart of Europe!


For all lovers of bottom fishing. Their streamlined shape ensures that these weights easily remain at the bottom of a body of water and offers very little room for maneuver to groundfish after taking the bait.

These products are particularly well suited for soft and muddy ground.


Mimics the natural shape of drops. These sinkers ensure better casting distances. Their design is highly aero- and hydro-dynamic, making these products ideal to cast bait over long distances and to ensure minimal resistance under water when reeling back in. The larger volume, compared with lead weights, also tends to have a positive effect on the descent rate.


Ideal for lovers of predator fishing, with excellent flow properties. Thanks to the specially optimized shape of the fixing pin, bait can be secured easily and the plastic fish sits tight without rotating. The angler can freely choose the quality and the number of preferred hooks. The relatively short fixing path does not restrict the bait in its mobility and allows deceptively natural-looking bait movements. The favorable weight distribution keeps the bait upright and easy to spot for the predator. Ground contact shows one of the advantages that steel offers over lead: its increased sound helps attract the attention of target fish.
