Derby vs Astra DE Blades: Which Budget Blade Wins?

I’ve burned through thousands of derby vs astra double edge razor blades over two decades, and the honest truth is this: Astra Superior Platinum edges out Derby Extra in almost every category that matters. Derby blades are forgiving and smooth, yes—but they sacrifice sharpness and longevity in a way that makes them frustrating for anyone with coarse facial hair or a preference for efficiency.

That said, Derby blades aren’t without merit. If you’re just starting wet shaving or you’ve got sensitive skin and fine hair, Derby’s mild cutting edge might be exactly what you need. But for the vast majority of shavers—especially those who’ve graduated beyond beginner status—Astra delivers sharper performance, better longevity, and more consistent results across different razor platforms.

The Core Difference: Sharpness vs. Forgiveness

The fundamental divide between these two blades comes down to sharpness. Astra Superior Platinum blades are noticeably sharper out of the wrapper. You feel it on the first stroke—clean, efficient cutting with minimal resistance. Derby blades, by contrast, feel duller from the start, which translates to more buffing and multiple passes to achieve the same result.

I tested both blades in identical razors—my grandfather’s 1959 Fatboy, a Merkur 34C, and a Karve Christopher Bradley—and the pattern held across all three platforms. Astra blades required fewer passes, delivered closer shaves with less irritation, and stayed sharp for 5-6 shaves. Derby blades started losing their edge by shave three, and I found myself working harder to get a clean result.

Why Derby Feels “Smoother”

Derby’s reputation for smoothness is real, but it’s a double-edged sword (pun intended). That smoothness comes from a less aggressive cutting edge. For beginners who are still learning blade angle and pressure control, this can prevent nicks and razor burn. But once you’ve dialed in your technique, that same smoothness becomes a liability—you’re left chasing stubble with extra passes, which ironically causes more irritation than a sharp blade would.

Real-World Testing: Three Razors, Two Blades

I ran both blades through a month-long rotation using three different razors to eliminate platform bias. Here’s what I learned.

Merkur 34C Heavy Duty (Mild Razor)

This is where Derby blades performed best. The 34C’s mild geometry compensated for Derby’s lack of sharpness, and the combination delivered decent shaves for beginners. But even here, Astra blades outperformed—sharper cuts meant less time on my face, which reduced irritation despite the more aggressive edge.

Derby required 3.5 passes on average (WTG, XTG, XTG reverse, plus touchup). Astra needed just 2.5 passes for the same result.

Gillette Fatboy (Adjustable, Set to 5)

This is my daily driver, the razor I inherited from my grandfather in 1999. At setting 5 (mid-aggression), Derby blades struggled. The shave felt tuggy by pass two, and I found myself cranking the dial to 7 just to compensate for blade dullness. That defeats the purpose of using a mild blade.

Astra blades sang in the Fatboy. Sharp, efficient, and smooth at setting 5. No tugging, no buffing, no need to adjust mid-shave. This is the combination I recommend to anyone asking about double edge safety razor blades for adjustable razors.

Karve Christopher Bradley (Medium Aggressive Plate)

Derby blades were outmatched here. The Karve’s efficient geometry demands a sharp blade to perform properly. Derby’s dull edge turned what should be a smooth two-pass shave into a frustrating exercise in multiple buffing strokes. I actually got more irritation with Derby than with Astra, despite Derby’s “gentle” reputation.

Astra blades paired beautifully with the Karve. Clean, close shaves in two passes. This is the blade I keep in this razor permanently.

Coating and Manufacturing: Why Astra Lasts Longer

Both blades use polymer coatings, but Astra’s platinum-chrome finish is noticeably more durable than Derby’s standard chrome coating. I’ve examined both under magnification (yes, I’m that kind of shaving nerd), and Astra’s edge shows less microchipping and deformation after multiple shaves.

Derby blades are manufactured in Turkey by a company that’s been making blades since 1952. Quality control is decent but not exceptional—I’ve found more variability blade-to-blade with Derby than with Astra. Some Derby blades feel sharper than others from the same pack, which suggests inconsistent honing or coating application.

Astra platinum razor blades are made in Russia (St. Petersburg) by Gillette/P&G, and the manufacturing consistency is excellent. Every blade feels identical, which matters when you’re trying to dial in your technique.

Who Should Choose Derby Blades?

I don’t want to completely dismiss Derby blades—they have a legitimate place in the wet shaving world. Here’s when I’d recommend them:

• Absolute beginners: If you’re making the jump from cartridge razors and you’re still learning blade angle, Derby’s forgiving edge can prevent bloodshed while you build muscle memory.
• Very sensitive skin: Some shavers genuinely can’t tolerate sharp blades without irritation, even with perfect technique. If that’s you, Derby might be your best option.
• Fine, sparse facial hair: If your beard growth is light and you’re shaving mostly peach fuzz, Derby’s mild edge is sufficient and won’t cause unnecessary irritation.
• Ultra-mild razors: If you’re using something like a Weishi 9306 or Merkur 23C, pairing it with Derby can work—though I’d still argue Astra is the better choice.

Who Should Choose Astra Blades?

For the majority of wet shavers, Astra Superior Platinum is the better blade. Specifically:

• Intermediate to advanced shavers: Once you’ve got your technique down, you want efficiency. Astra delivers that.
• Coarse or dense facial hair: If you’re blessed (or cursed) with thick beard growth, you need sharpness. Derby will leave you frustrated.
• Adjustable or aggressive razors: Razors like the Fatboy, Progress, or Rockwell 6S need a sharp blade to perform properly. Astra fits the bill.
• Anyone who values longevity: At roughly the same price point, Astra gives you twice the shaves per blade. That’s better value.

Price and Value: Nearly Identical Upfront, Different Long-Term

Both blades cost roughly $0.08-$0.12 per blade when bought in bulk (100-count packs). But Astra’s superior longevity changes the value equation. If Derby lasts 3 shaves and Astra lasts 6, you’re effectively getting half the cost-per-shave with Astra.

I buy Astra Superior Platinum 100-blade packs and they last me about eight months of daily shaving. With Derby, I’d need two packs to cover the same period. That’s not a huge financial difference, but it’s worth noting.

The Verdict: Astra Wins for Most Shavers

After 22 years of wet shaving and testing hundreds of blade varieties, I keep coming back to Astra Superior Platinum as the gold standard for budget blades. They’re sharper, more consistent, and longer-lasting than Derby Extra. The only scenario where Derby makes sense is for absolute beginners or shavers with very specific skin sensitivity issues.

If you’re still undecided, here’s my recommendation: buy a sample pack that includes both. Spend a week with Derby, then a week with Astra, using the same razor and same technique. By day three of the Astra week, you’ll understand what I’m talking about. The difference in sharpness and efficiency is that noticeable.

And if you’re looking to branch out beyond these two, consider trying Feather double edge blades (sharper than Astra but less forgiving) or Gillette Silver Blue blades (similar to Astra but slightly smoother). Blade exploration is half the fun of this hobby.

Frequently Asked Questions

Are Derby blades sharper than Astra?

No. Astra Superior Platinum blades are noticeably sharper than Derby Extra blades. This is evident from the first stroke—Astra cuts through facial hair with less resistance and requires fewer passes to achieve a close shave. Derby’s milder edge is more forgiving for beginners but sacrifices cutting efficiency.

How many shaves can you get from Derby vs Astra blades?

Derby Extra blades typically deliver 2-3 quality shaves before becoming noticeably dull. Astra Superior Platinum blades last 5-6 shaves before requiring replacement. This longevity difference makes Astra the better value despite similar upfront costs.

Which blade is better for sensitive skin?

Derby blades are often recommended for sensitive skin due to their milder edge, but this can be misleading. A sharp blade like Astra actually causes less irritation for most shavers because it cuts cleanly in fewer passes. Derby’s dull edge requires more buffing strokes, which can increase irritation. The exception is absolute beginners who haven’t yet mastered proper blade angle and pressure.

Can I use Derby blades in an aggressive razor?

You can, but it’s not an ideal pairing. Aggressive razors like the Karve Christopher Bradley, Muhle R41, or Fatboy (set to 7+) are designed to work with sharp blades. Using Derby blades in these razors results in tuggy, inefficient shaves that require multiple passes and can actually cause more irritation than a sharper blade would.

Are Astra blades made by Gillette?

Yes. Astra Superior Platinum blades are manufactured in St. Petersburg, Russia, by Gillette (owned by Procter & Gamble). This gives them access to Gillette’s manufacturing technology and quality control processes, which contributes to their consistency and reliability compared to Derby’s Turkish manufacturing.
