Most people buying their first clipper assume the motor does the work. The blade does. A 7,200 SPM rotary motor with a worn or wrong-profile blade will pull, snag, and leave tracks across a head, while a 5,500 SPM magnetic motor with a freshly sharpened, properly tensioned blade will glide. Once you understand what each blade is built to do, picking the right one for the cut takes about three seconds and the result on the head looks intentional instead of accidental. This guide walks through the materials blades are made from, the geometries you will actually encounter, and the practical rules for matching blade to job.
Blade material: stainless vs carbon vs ceramic
Three materials cover roughly 95 percent of the clipper blades on the market in 2026.
Stainless steel
The default for most stock blades that ship with consumer clippers. Stainless resists rust well, takes a decent edge, and is forgiving when dropped. The trade-off is that stainless dulls faster than carbon or ceramic and runs warmer because the alloying elements that fight corrosion (chromium, nickel) reduce thermal conductivity. Stock stainless blades on a Wahl Magic Clip or Andis Master typically need professional sharpening at the 6 to 9 month mark in daily use.
Carbon steel (high carbon)
High-carbon steel takes a sharper, more aggressive edge than stainless and holds it noticeably longer. The classic Andis SuperBlade and most “DLC” coated competitor blades start with a high-carbon core. The downside is rust. Skip oiling for a week in a humid bathroom and a carbon blade will pit. If you maintain a strict oil-after-every-cut habit, carbon is the better cutting material.
Ceramic
Ceramic blades (zirconia-toughened alumina is the common formulation) stay roughly 75 percent cooler than steel at the same SPM, hold an edge 4 to 5 times longer, and never rust. They are also brittle. A single drop on tile usually cracks one or more cutting teeth, and replacement runs $25 to $60. Pros who never drop blades love ceramic. Beginners are better off with stainless until their tool-handling is consistent.
What about titanium-coated blades?
Most “titanium” blades are stainless or carbon steel with a thin titanium nitride coating that adds surface hardness. The coating reduces friction and heat for the first few months. Once it wears through, the underlying steel takes over. Titanium-coated is a useful middle ground but not a different material class.
Blade geometry: taper, fade, T-blade, skip-tooth
Taper blade
The all-purpose workhorse. A taper blade sits flush in the clipper housing and cuts at a length determined by the lever position, typically from about 0.8 mm (lever up) to 2.5 mm (lever down). Stock blades on most barber clippers (Wahl Magic Clip, Andis Master, Oster Classic 76) are tapers. Use a taper for bulk removal, for blending, and for any cut where you want a smooth lever-driven length change without swapping blades.
Fade blade
A fade blade is a taper that has been “zero-gapped” or shipped with a tighter factory gap so the lever-up position cuts at roughly 0.4 to 0.5 mm. The cutting teeth on a true fade blade are also tapered to a sharper profile so the cut blends into skin rather than leaving the visible step a fully zero-gapped blade produces. Use a fade blade when you want a clean low-fade or skin-tight blend without committing to a full bald-skin finish.
T-blade
The T-blade has cutting teeth that extend wider than the blade housing on both sides, forming the T shape. The extended teeth reach into hairlines, around ears, around the contour of a beard, and along the neckline without the housing blocking your view of the corner. Use a T-blade for outlining, line-ups, beard detailing, and edge work. T-blades are not ideal for bulk removal because the wider cutting surface flexes more under load.
Skip-tooth (wide-tooth) blade
A skip-tooth blade has alternating long and short teeth so the long teeth pre-comb the hair before the short teeth cut. Skip-tooth blades are used for thick, matted, or coarse coats (most often on dogs and horses) and rarely belong on a human haircut. If you bought a pet clipper combo and one of the blades looks like the teeth are missing every other one, that is the skip-tooth.
Blade sizes and numbering
The two number-systems you will encounter:
Wahl lever-position numbering
Wahl clipper blades are usually one piece (not detachable) and lengths are controlled by the lever and by snap-on guards (#1 = 3 mm, #2 = 6 mm, and so on). The blade itself has a number stamped on it (00000, 000, 0, 1) representing the closeness at lever-up position. Lower numbers cut closer.
Andis / Oster detachable-blade numbering
Andis and Oster (and any clipper using the A5 standard) use detachable blades numbered by cutting length:
- #40 = 0.25 mm (surgical)
- #30 = 0.5 mm
- #15 = 1.2 mm
- #10 = 1.5 mm
- #7F = 3.2 mm
- #5F = 6.3 mm
- #4F = 9.5 mm
- #3F = 13 mm
The “F” suffix means full-tooth (cuts straight across), no suffix means skip-tooth.
Practical matching: which blade for which job
| Job | Best blade type |
|---|---|
| Bulk removal (taking a 4 down to a 2) | Stock taper blade |
| Low fade, smooth blend into skin | Fade blade (zero-gapped taper) |
| Bald fade / skin fade | Foil shaver or zero-gapped T-blade |
| Outlining, line-up, beard corners | T-blade |
| Neckline cleanup | T-blade or trimmer |
| Pet grooming (matted coat) | Skip-tooth blade |
| Surgical prep (vet, pre-op shave) | #40 detachable |
Maintenance that actually matters
A new blade with no oil lasts about 20 minutes before it starts pulling. A cleaned and oiled blade keeps cutting for years. Three habits cover most of it:
- Brush the loose hair out of the teeth after every cut
- Apply 3 drops of clipper oil (not 3-in-1, not WD-40) along the cutting teeth and run the clipper for 5 seconds
- Once a month, remove the blade, clean with blade-wash, dry fully, oil, and reassemble
Pulling, hot blades, and tracks across the head are nearly always either a dull blade, a blade that needs oil, or a blade with the gap set wrong. Material and geometry decisions matter, but maintenance is what keeps the blade performing the way it was designed to. See our guide to cleaning and oiling clipper blades for the step by step routine.

Frequently asked questions
What is the difference between a taper blade and a fade blade?+
A fade blade is a taper blade with a tighter zero-gap and a slightly extended cutting tooth profile that takes the cut closer to the skin without the bald-line a true zero-gapped blade produces. Most fade blades cut around 0.4 to 0.5 mm, while a stock taper sits closer to 0.8 to 1.0 mm at lever-up position.
Is a T-blade better than a regular blade for line-ups?+
Yes for outlining and edge work. The T-blade extends past the housing so the corners reach into hairlines, around ears, and along beard borders without the housing getting in the way. For bulk hair removal a standard taper still cuts faster.
Are ceramic blades worth the extra money?+
Ceramic stays cooler and holds an edge roughly 4 to 5 times longer than carbon steel in published manufacturer testing, but it is brittle. Drop a ceramic blade once on a tile floor and you have likely cracked it. Stainless is the more forgiving choice for most home users.
How often should I replace a clipper blade?+
Heavy professional use replaces blades every 6 to 12 months. Home users who clean and oil after each cut can stretch a quality blade well past 3 years. Replace when you feel pulling, see uneven cutting, or notice visible chipping on the tooth tips.
