Product description

GERA represents the pinnacle of German scissor manufacturing. The exclusive Niolox steel, developed and manufactured in Germany, is used in scissor production exclusively by TONDEO worldwide. The addition of niobium, vanadium, and molybdenum, along with an increased chromium content, gives this steel exceptional properties: a hardness of 60±1 HRC (60–62 HRC for hair scissors) combined with a toughness of 50–60 J/cm²—a combination that is virtually unmatched. Hardened at 1100°C using the Solingen hardening process, “ GERA ” is stainless, nickel-free, and resistant to scratches and corrosion, with over 500 hours of resistance in salt spray testing.

The revolutionary ball-bearing screw system—which, in the case of the modeling shears, consists of a miniature deep-groove ball bearing with eight stainless steel balls—virtually eliminates friction and reduces the required closing force to just 30 grams, a 50% reduction compared to conventional two-piece screw systems. With ultra-fine detents adjustable to the millimeter and a rating of 2 on the Borg CR-10 scale for tool ergonomics, this system comes with a lifetime warranty. With 1.5 million proven cutting cycles, this significantly reduces strain on the muscles and ensures consistent precision even during intensive workdays.

CONBLADE technology, featuring an extreme concave grind and a convex outer blade, reduces sliding resistance by 40–50%—allowing for precision cuts with a deviation of less than 0.1 mm even after hundreds of thousands of cuts. With the GERA Offset (15) texturizing shears, the CONBLADE technology—featuring wide, structured serrations—enables both powerful chunking and sophisticated texturizing: As an innovative hybrid of a chunker and a texturizer, it removes 30–50% of the hair with each cut using its 15 wide teeth, effortlessly creating bold, textured looks for modern styling needs. The 1.0 cm offset thumb loop ensures optimal ergonomics for fatigue-free work for hours on end, while the rounded, rear-sloping finger rest provides a secure grip during cutting.

Gera Duo – Hair Scissors 6.25 Conblade + Gera 5.75 (15)

Hairdressing scissors hair professionally

The perfect combination for precise cuts and bold textural effects: The GERA features precise, sharp, and ergonomic blades for creating graphic lines, base lines, and layers at any angle—whether working with fine or thick hair, it handles every hair texture effortlessly and without clogging.

The GERA Offset (15) complements this as a styling scissors with 15 wide teeth for bold chunking, broken textures, and dynamic movement—ideal for modern looks like curtain bangs and textured sections. Whether you have medium-thick or thick hair, these scissors remove up to 30–50% of the volume while creating expressive, clearly defined textures. The diamond-hard Niolox blade and friction-free ball bearing ensure effortless, energy-saving use.

Both pairs of scissors are synonymous with precision, comfort, and professional, modern results.

Hand cleans high-quality Hairdressing scissors

Durability that needs to be maintained.

TONDOE PREMIUM hair scissors are as Long-lasting they are high-quality. With up to 1.5 million cuts without resharpening thanks to Conblade® technology. To maintain sharpness and function, we recommend:

Cut only hair
Clean after each use with a soft cloth
Targeted lubrication in the screw area with special oil
Store in a dry place in the original packaging.
Maintenance with TONDEO

Note: The blade is particularly sensitive. Even the smallest dust particles can damage the blade. For this reason, the scissors are carefully demagnetized in our factory so that they do not attract tiny particles. Avoid contact with magnets.

CONBLADE is at the heart of TONDEO premium scissors:

Extremely concave side: Lowest possible cutting angle for razor-sharp edges
Extremely convex outer blade: 4 times more stable than conventional shapes
Selective contact with the cutting surfaces: Maximum sharpness with minimal friction
45° immersion angle during grinding: precision with ±0.02 mm deviation
40-50% reduced sliding resistance: Drastically lower force requirement

Messergebnisse: Schließkraft: 10-25 Gramm; Lebensdauer: 1,5 Millionen nachgewiesene Schneidzyklen; 3-fache Schnitthaltigkeit im Vergleich zu herkömmlichen Scheren; Präzisionsschnitte <0,1mm Abweichung; 20-25% gleichmäßigere Kraftverteilung über die Klinge

What is CONBLADE and what advantages does it offer?

The patented CONBLADE combines an extremely hollow (concave) ground cutting edge with an extremely convex blade. This design ensures:

Lowest possible cutting angle with razor-sharp cutting edge
3 times longer cutting life compared to conventional shears
40-50% reduction in sliding resistance thanks to optimized geometry

Up to 80% less effort required: only 10-30g closing force instead of the industry standard 50-100g

What does the BESS scale value mean?

The BESS value(Brubaker Edge Sharpness Scale) is a standardized measurement for quantitatively determining cutting edge sharpness. The measurement is based on the principle of cutting tests under defined loads: a calibrated test medium is exposed to the cutting edge while the force required in grams (g) to completely cut through the test material is measured. The scale is inversely proportional to sharpness: a lower BESS value indicates greater cutting edge sharpness, as less force is required for the cutting process. By using a standardized, certified test medium under controlled conditions, the BESS method ensures reproducible and comparable measurement results across different blades and manufacturers. For comparison: an ultra-sharp razor blade has a BESS value of approx. 50, while high-quality cutlery has a value of around 300.

What does the BORG-Scala value mean?

The BORG CR-10 scale for tool ergonomics Studies on fabric scissors showed a reduction in perceived effort from traditional designs (higher BORG values) to ergonomic designs through principles such as "bend the tool, not the wrist." Calibration studies with hand dynamometers confirm the correlation between objective force measurements and subjective BORG ratings. It is assessed whether the hand, elbow, or shoulder must be twisted or whether work can be performed in a natural hand position. Feather-light tools have a BORG value of 1, high-quality precision tools have a value of 2-4, and tools that cause fatigue or are even harmful to health are rated 7-10.
