🔴 Possible disadvantages
⚠️ It’s not legal everywhere: Automatic knives are not allowed in some countries or regions – check legislation before buying.
⚠️ Larger dimensions: over 26 cm in length and a sharper profile make this knife less suitable for discreet EDC carry.
⚠️ One-sided clip: the clip is not reversible – the knife is designed primarily for right-handed users.
🛠️ Maintenance and grinding
The use of 154CM steel makes the knife durable, but regular care is recommended to keep it sharp. It is well suited for blade maintenance and easy blade restoration:
🔧 Spyderco Tri-Angle Sharpmaker (204MF) – a very popular sharpener that allows easy and precise sharpening even for users without experience, available on our website Moskito.cz. It is ideal for maintaining a satin finish on harder steel such as 154CM.
To maintain functionality:
- Lubricate button and axle with suitable oil (e.g. KPL)
- Keep dry and clean of dirt
- Do not open the automatic by force (despite resistance)
