Professional shears, combs and razors — engineered by ProHair

Otto is ProHair's own professional tool brand. Rather than reselling someone else's shears under a licence, we specify, build and stand behind these tools ourselves — which is why the steel grade, the blade geometry and the handle design are stated plainly on every product page instead of hidden behind marketing language.

The cutting range is built in Japanese 440C stainless steel: a high-carbon, high-chromium grade that hardens to roughly 58–60 HRC, holds a convex edge through months of professional use and resists the colour, bleach and perm chemistry a salon blade meets every day. The 6-inch professional shear uses extreme hollow ground convex blades — the geometry that makes true slice cutting possible — on a 3D-offset handle with an ergonomically angled thumb hole, because the handle is what decides whether your thumb joint still works in ten years.

Alongside the shears sit seven carbon-fibre combs — cutting, barber, pin tail, flat-top clipper, lift and all-purpose — that are anti-static, heat resistant and light enough to work with all day, plus a guarded haircutting razor for feathering and lived-in texture. Everything is priced in Canadian dollars with current stock shown on the product page. The six expert guides below explain how to choose between them.

Which Otto Products Are Right for You?

Foundational cutting

Best for: Blunt lines, graduation, layering and scissor-over-comb

Start with the 6-inch professional shear. Six inches is the deliberate middle of the range — long enough for comb work, short enough to detail with, and the length that suits the widest band of hand sizes.

Slice and dry detail work

Best for: Point cutting, slide cutting and soft dry texture

This needs a convex edge, not a serrated bevelled one. The extreme hollow ground convex blade lets hair travel along the blade instead of gripping it, which is the whole mechanism behind slice cutting.

Blending and weight removal

Best for: Softening transitions, de-bulking dense hair, refining a line

A thinning shear removes at a set depth with a repeatable result. Stay 2.5–5 cm off the scalp, work dry where you can, and take one pass before you look.

Soft, lived-in texture

Best for: Feathering ends, undone finishes, movement through mid-lengths

A razor tapers the hair shaft rather than cutting it square, so the result is softer than any shear can produce. Use on damp hair with a fresh blade; go carefully on coarse or curly hair.

Sectioning, parting and colour work

Best for: Foils, balayage, updos, braiding and precise partings

The pin tail comb's slim metal tail places sections cleanly; the dual-tooth styling and all-purpose combs handle distribution and smoothing between steps.

Short-hair shaping and clipper work

Best for: Flat tops, tapers, fades and clipper-over-comb

A long working edge gives a consistent guide for clipper- and scissor-over-comb. The flat-top and barber combs are built for that job; the lift comb handles root volume and textured hair.

Tool care and longevity

Best for: Protecting a 440C edge and an adjustable pivot

Wipe after every client, clean and oil the pivot at the end of every day, drop-test the tension weekly, and only ever let a convex specialist sharpen a convex edge.

Frequently Asked Questions

What is Otto, and who makes it?
Otto is ProHair's own professional tool brand. We specify and build the range ourselves rather than reselling a licensed line, which is why the steel grade, blade geometry and handle design appear plainly on each product page. It also means the tools are sold at a working professional's price rather than a distributor's markup — the 6-inch professional shear is $96.00 and the thinning shear $99.99.
What does 'Japanese 440C steel' actually mean?
440C is a high-carbon (roughly 0.95–1.20%), high-chromium (16–18%) martensitic stainless steel. The carbon lets the blade be hardened to about 58–60 HRC so it holds a fine convex edge; the chromium forms the passive layer that resists the colour, bleach and perm chemistry a salon blade meets daily. 'Japanese' refers to where the steel is milled — Japanese mills are known for tight alloy consistency and low inclusion counts, which matters because a single inclusion at a convex edge is a future chip. Our 440C guide compares it against 420, VG-10 and powder-metallurgy steels.
What is the difference between convex and bevelled blades, and does it matter?
It decides which techniques the shear can perform. A bevelled edge is ground flat, usually with a micro-serration that grips the hair — robust, forgiving, and excellent for blunt wet cutting. A convex edge is ground on a curve to a very acute apex with no serration, so it parts hair rather than pinching it. Slice cutting only works on a convex edge: on a serrated blade the hair bunches and you get a chewed result instead of a clean taper. If dry detailing and slice cutting are part of your work, convex is a requirement, not an upgrade.
What does 'extreme hollow ground' mean?
Hollow grinding is separate from the edge grind. It is the concave scoop machined into the inside face of the blade behind the edge, so the two blades touch essentially only where they cross rather than riding against each other along their whole length. Extreme hollow grinding minimises that contact further. In practice you get less friction and heat, a quieter and smoother cut, the ability to run lighter tension — which reduces hand fatigue — and blades that stay sharp longer because they are wearing against each other less.
What does a 3D-offset handle do that a normal handle does not?
An offset handle sets the thumb ring shorter and further forward so you can keep the blade level with your elbow down and your shoulder relaxed, instead of the 'chicken wing' posture that symmetrical opposing handles force. A 3D-offset goes further: the thumb ring is angled and canted so the thumb sits in its natural resting plane rather than being twisted into line with the blade. Combined with an angled thumb hole, that removes the residual rotation at the thumb base — the joint that develops arthritis and De Quervain's tenosynovitis. If you already get a nagging ache at the base of your thumb after a long day, this is the change most likely to help.
What shear length should I buy?
Measure from your wrist crease to the tip of your middle finger; that measurement in inches is roughly your baseline length. Then adjust for your work: shorter (5.5"–6") for precision, fringes and dry detailing; longer (6.5"–7") for barbering and scissor-over-comb. Otto builds at 6 inches deliberately — it is the length that will disappoint the fewest people if you are buying a single shear. Hold it before you commit: if you have to stretch or curl your thumb to reach the ring, it is the wrong size for you and getting used to it will not fix that.
How many teeth does the Otto thinning shear have?
The current product page does not publish a tooth count, and we would rather say so than guess. What it does specify is the construction — one toothed blade against one straight blade — and the intended job: blending, softening transitions and removing controlled weight without the blunt result of a cutting shear. That places it in the blending-to-texturizing role rather than the chunker role. As a rule, more teeth removes less hair and blends more softly; fewer teeth removes more and shows more. If an exact count matters for your work, contact us before ordering and we will count it.
Is the shear set better value than buying separately?
Marginally, and the real benefit is matching rather than money. The 6-inch Haircutting & Thinning Shear Set is $189.99; the same two tools bought separately are $96.00 plus $99.99, or $195.98. The saving is small. The reason to buy the set is that both shears are built at the same length with the same handle geometry, so they feel consistent in the hand — which matters more over a full day than six dollars does.
How do I look after a professional shear?
Wipe the blades with a soft dry cloth after every client, and immediately after any colour or bleach service. At the end of the day, clean, dry completely — including the pivot — and put one drop of shear or clipper oil into the joint, working it through and wiping away the excess. Never use WD-40, 3-in-1 or cooking oil. Drop-test the tension weekly. Never soak a shear or leave it in disinfectant longer than the product specifies, and never store it in a drawer with clippers and clips. The full routine takes about ninety seconds a day.
How often should shears be sharpened, and who should do it?
Sharpen when the shear fails the tissue test — folding or pushing a single ply instead of slicing it — not on a schedule. For a full-time professional with good maintenance that is roughly every 6 to 12 months. Who does it matters more than when: a convex-edged Japanese-style shear must be sharpened on a flat rotary hone by a technician who works on convex edges. A general knife sharpener or a standard bevel jig will grind a bevel onto the convex geometry and destroy it permanently — the shear will still cut, but it will never slice cut again.
Why carbon fibre for the combs rather than plastic?
Three practical reasons. Carbon fibre is anti-static, so the comb is not fighting flyaway during a blow-dry or a precision section. It is heat resistant, so it survives working near an iron or dryer without deforming the way a moulded plastic comb will. And it is light and thin, which means better visibility and manoeuvrability and less hand fatigue over a full day. It is heat resistant rather than heat proof, though — leave one pressed against a hot barrel and it will still warp.
Which Otto comb should I start with?
If you want one comb, take the 7-inch Styling Comb ($5.99) or the 8.5-inch All-Purpose Comb ($6.99) — both have a dual layout with fine teeth for precise smoothing and wider teeth for distribution. Add from there by job: the 9-inch Pin Tail Comb for foils, partings and colour work; the 9.5-inch Flat Top Clipper Comb or 9-inch Barber Comb for clipper- and scissor-over-comb; the 8.5-inch Cutting Comb for precision cutting; the 7.5-inch Five-Prong Lift Comb for root lift and textured hair.
