Quick Verdict
Compact EDC folder featuring AR-RPM9 powder steel at HRC59-61 with a Wharncliffe blade profile. The 2.17" blade paired with ceramic ball bearing pivot delivers smooth action. Lightweight 53g aluminum handle with button lock provides secure blade retention. Good value option for everyday carry with quality materials typically found in higher-priced knives.
What We Like

- Ceramic ball bearing pivot for smooth, fast deployment
- Lightweight aluminum handle at only 53g
- Button lock provides secure and easy one-handed operation
- Wharncliffe blade shape excels at precise cutting tasks
Considerations
- Small 2.17" blade length may be limiting for larger tasks

- Aluminum handles can scratch more easily than G10 or Micarta
