What Is M-Tech?
M-Tech is a budget knife brand producing a wide range of folders and assisted openers at entry-level price points ($15–$25). The MT-A845 is a spring-assisted folder in a tactical aesthetic — black handle scales, partial serration, and a clip-point blade.
Specs
- Blade length: 3.5 inches
- Steel: 440 stainless (likely 440A)
- Hardness: ~55–57 HRC (estimated)
- Lock: Liner lock
- Mechanism: Spring-assisted (torsion bar)
Opening Mechanism
The spring-assist mechanism deploys the blade quickly. Occasional misfires occurred during testing when the knife was new. After 50–100 cycles, deployment became more consistent. This level of quality-control variability is expected at this price point.
Blade Steel Performance
440A at 55–57 HRC is honest budget territory. The knife arrives sharp enough for basic tasks. Edge retention under daily light use is adequate for 2–3 weeks before a touch-up is needed. Sharpening is easy — soft steel responds quickly to any sharpening method.
Build Quality
The liner lock engages reliably but with noticeable side-to-side blade play — typical of budget folder construction. The pivot screw loosened during testing (easily re-tightened with a Torx driver). For non-demanding EDC tasks the lock is adequate. Do not use this knife for prying or heavy tasks.
The M-Tech MT-A845 is exactly what it is: a functional $15–$25 spring-assist folder with adequate steel and a working liner lock. It's a backup, a glove-box knife, or a gift for someone who just needs a cutting tool. At its price, it passes the minimum bar for basic utility use.
