K25 Contact Trainer Knife Red Rubber (31994-RO)
- K25 Contact Trainer Red Rubber (31994-RO) – realistic dagger-type training knife made entirely of red technical rubber. Safe hand-to-hand combat simulator for tactical exercises, self-defense, and defensive training.

This product is intended for use only by adults with knowledge and experience in handling sharp cutting tools. Improper use of the knife can result in serious injuries. The blade is extremely sharp and can easily cut through skin and tissue; therefore, extra caution should always be exercised while cutting, and hands should be kept away from the cutting edge. To prevent the knife from slipping, it is recommended to cut on a stable, non-slip surface and avoid excessive force, which may cause uncontrolled blade movement.
Leaving the knife on the edge of a table, countertop, or in easily accessible places—especially where children are present—poses a significant safety risk. The knife should always be properly secured after use, ideally by placing it on a stable surface or storing it in designated knife blocks, protective sheaths, or magnetic strips. The knife should never be used for tasks it is not designed for, such as opening cans or prying objects, as this can damage the tool and lead to dangerous accidents.
A dull blade increases the risk of injury, as it requires more force and is more likely to slip from the material being cut. Therefore, it is essential to sharpen the knife regularly to maintain optimal sharpness. Additionally, proper cleaning and drying of the knife are necessary to prevent corrosion and bacterial growth. Periodic inspection of the handle and blade is recommended to check for cracks, chips, or looseness. If any damage is detected, the knife should be repaired or replaced immediately.
When using the knife, focus solely on the task at hand—avoid talking on the phone, watching television, or other distractions while cutting. Ensure proper lighting in the workspace for better visibility and control. Please note that some countries or regions have laws restricting the ownership and carrying of knives. Before purchasing or using this knife, verify that its use is legal in your location according to applicable regulations.
Following these safety guidelines will help ensure safe and effective knife use, minimizing the risk of accidents and extending the lifespan of the tool.
The K25 Contact Trainer Red Rubber (31994-RO) is a specialized training knife created by the K25 brand to safely yet realistically replicate the work of a combat tactical knife. This model replicates the profile of the Dagger, which allows you to practice both cutting and thrusting sequences with full control over the tool. The red technical rubber, from which the whole is made, provides the right balance between flexibility and hardness, minimizing the risk of injury during contact training. The bright color of the blade serves a warning function and increases visual safety in dynamic conditions. The ergonomic handle with contoured and non-slip texture supports precise handling of the tool. The model is designed for instructors, martial arts practitioners, uniformed services and self-defense enthusiasts who need a training tool with high functionality and wear resistance. It comes with a black nylon sheath, making it easy to transport and organize the equipment. 31994-RO is a proposal that combines safety of use with realistic combat geometry, meeting the expectations of the most demanding users.
Blade - with a Dagger profile is made of red technical rubber and is free of sharp edges, allowing safe contact practice. The flexible but durable design allows replicating real combat sequences without the risk of cuts. Rounded cutting lines and a smooth surface make it easy to clean up after a session, while proper balance ensures smooth movements and proper tool control. Intense red color uniquely identifies the knife as a safe training simulator, complying with health and safety rules in training rooms and tactical training.
Handle - an integral part of the design made of the same red rubber compound, as the Blade. Its ergonomic profile with pronounced finger recesses ensures a secure grip in all conditions - even with a wet or sweaty hand. The slightly textured surface improves grip and increases the comfort of manipulation. The elasticity of the material prevents breakage and allows repeated use in intense training sessions. Included is a durable black nylon sheath, allowing the tool to be safely carried and stored. This is a refined solution for those looking for an effective and rugged training knife with realistic balance and form.
