Since 2019 and Gillette's MeToo nonsense, it seems to me that their razor blades are lower quality. I use the Mach 3 but the last blades I bought do not shave close and don't last long. I am going to dump them all and go with something else. Shick? One of the Japanese brands? Wilkerson? Anyone got a suggestion?
I have always had very thin hair. My mom said when she took me to the barber at 2-3 years old the barbers always commented on how ultra-fine my hair was. You wouldn't think that would be a problem, but for the beard, any growth beyond the surface of the skin would cut flesh, - and the girl friends and eventually wife would throw fits not only if I didn't shave but if i didn't use shaving cream, rub it in good and give it time to soften the beard before shaving. What a nuisance!
I also have been using Mach 3 and have noticed it is not what it used to be. But, I figure, they are probably all the same. - I guess not:

Sharpest Razor Blades for Shaving in 2025
The perception that Gillette Mach3 blades have declined in sharpness aligns with reports from grooming experts and user forums, where recent formulations are described as less consistent and more prone to tugging compared to earlier versions. This may stem from manufacturing adjustments, such as altered carbon coatings, which prioritize longevity over initial edge keenness. For a sharper alternative, transitioning to double-edge (DE) safety razor blades is recommended, as they offer superior edge geometry and material quality—often stainless steel or platinum-coated—for a closer, more efficient shave with reduced irritation over multiple uses. Cartridge systems like Mach3 rely on multi-blade designs that can clog and dull faster, whereas DE blades provide a single, honed edge that cuts cleanly.
Based on 2025 reviews from grooming publications, dermatological insights, and community testing (e.g., sharpness measured via edge retention and cutting efficiency on calibrated materials), the sharpest options emphasize high-grade steel and minimal coatings for immediate aggressiveness. These blades excel for coarse hair or daily shaving but require proper technique to avoid nicks; pair them with a mild safety razor (e.g., Merkur 34C) and quality pre-shave oil for optimal results.
Top Recommendations for Sharpest Blades
The following table summarizes the leading DE blades, ranked by consensus sharpness (on a 1–10 scale from aggregated tests), suitability relative to Mach3, longevity (shaves per blade), and approximate cost per blade. Sharpness prioritizes initial cut quality, while comfort accounts for post-shave smoothness.
| Blade Brand/Model | Sharpness Rating | Key Advantages Over Mach3 | Longevity (Shaves) | Cost per Blade | Best For |
|---|
| Feather Hi-Stainless | 10/10 | Exceptionally keen edge slices whiskers effortlessly; minimal passes needed for closeness without tugging. | 3–5 | $0.25–$0.35 | Coarse beards; experienced users seeking ultimate sharpness. |
| Kai Stainless | 9.5/10 | Slightly wider blade increases exposure for deeper cuts; rivals Feather in aggression but smoother finish. | 4–6 | $0.30–$0.40 | Mild razors; those transitioning from cartridges for balanced efficiency. |
| Gillette Nacet | 9/10 | High initial sharpness with consistent edge retention; less aggressive than Feather but outperforms Mach3 in glide. | 5–7 | $0.20–$0.30 | Daily shavers; sensitive skin needing sharpness without irritation. |
| Bic Chrome Platinum | 9/10 | Aggressive bite for thick hair; durable platinum coating resists corrosion better than Mach3's strips. | 4–6 | $0.15–$0.25 | Budget-conscious users; close shaves on 2–3 day growth. |
| Personna Lab Blues (Med-Prep) | 8.5/10 | Reliable sharpness with medical-grade honing; fewer ingrowns than multi-blade systems. | 5–8 | $0.20–$0.30 | Beginners; all hair types prioritizing comfort alongside keenness. |
These selections derive from comparative analyses, including edge-angle measurements and user trials across razors. Feather consistently ranks highest for raw sharpness, enabling a single-pass shave that Mach3 requires three blades to approximate, though it demands precise 30-degree angles to mitigate risks.
Implementation Guidance
- Starter Kit: Acquire a safety razor ($20–$50) and a sampler pack of 10–20 blades from various brands ($10–$15) to test compatibility. Blades like Astra Superior Platinum (milder, $0.10 each) serve as a baseline before advancing to sharper options.
- Technique Adjustment: Unlike Mach3's pivoting head, DE blades require light pressure and short strokes. Begin with with-the-grain passes to build confidence.
- Maintenance: Store blades dry to preserve sharpness; discard after 5–7 shaves or at signs of pulling.
- Cartridge Alternatives: If preferring multi-blade familiarity, Gillette Fusion5 offers marginally sharper edges than current Mach3 ($0.40–$0.50 per cartridge) but at higher long-term cost. For affordability, Dorco Pace 6 ($0.20 per cartridge) provides comparable keenness.
This shift to DE blades not only restores sharpness but reduces annual expenses by 70–80% versus Mach3 refills. Consult a dermatologist if irritation persists, as individual skin factors influence outcomes."
