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.
Tonic Grey Titanium / Natural Canvas Micarta, Satin, a strong EDC folding knife designed by Colin Maisonpierre, owner of CM KnifeDesigns.

An excellent tool for everyday carry!
M390 - martensitic high-performance chromium steel produced by powder metallurgy. Due to the alloy concept, it has extremely high wear resistance and high corrosion resistance. Due to its high wear resistance, it adequately maintains the shape of the edge, so the blade stays sharp for a very long time (requiring minimal maintenance). Another of the advantages is resistance to the formation of "wire" during sharpening. The steel has a high chromium content of 20.0% (Cr) doped with 1.9% carbon (C), vanadium 4.0% (V), and is hardened between 59-61 HRC. This super steel is comparable to Carpenter's CPM 20CV or CTS-204P steels. Manufactured by Böhler Edelstahl in Kapfenberg, Austria.
Blade - Reverse Tanto type, with an elegant Satin finish. The gentle curve of the cutting edge converges towards the needle-sharp tip of the knife. The thickness of the blade provides high strength while the high, flat grind gives excellent cutting edge geometry and extreme cutting performance. Ball bearings support the opening of the blade with a dual thumb stud in the wedge on both sides. The entire blade is locked with the proven and popular back lock.
Handle - grips made of Micarta, a virtually indestructible plastic that is insensitive to weather conditions, resistant to chemicals and mechanical damage, and titanium bolsters. The titanium backspacer to which the grips are attached guarantees the rigidity and strength of the entire structure. The two-position (right/left) clip allows you to carry the knife in tip-up position, with the tip of the blade upwards.
Case - the knife is packed in a zippered nylon soft pouch with the brand's logo for safe carrying and storage of the folder.
