BM 5370 is a fully automatic over-the-air (OTF) knife known for its light weight and high performance, designed for tactical and outdoor scenes.
The blade is made of CPM-CruWear powder tool steel with a hardness of 63-65 HRC, which is both highly wear-resistant and impact-resistant, and is suitable for high-intensity use scenarios. The handle is made of Grivory carbon fiber composite material, which is both light and stable to hold.
The knife performed well in tests such as chopping and piercing, and its blade retention was good, making it suitable for camping, rescue and other scenarios. Some users reported that its lightweight design reduced fatigue after long-term use. Violent tests showed that the blade did not deform or break when piercing hard objects or cutting ropes, and the spring mechanism was very stable.
BM 5370 is lightweight, high hardness, smooth opening and closing, suitable for EDC carrying, strong concealed carrying capability, and meets daily tool needs.
