Shears are the one category where the advice groomers give each other openly contradicts the advice the shops give, and both sides are right.
The shops will tell you a good pair of shears is an investment that lasts decades with proper care. True.
Groomers on their fourth year will tell you they buy inexpensive shears in threes and bin them when they dull, because sharpening costs more than replacement. Also true.
The reason both hold is that they are answers to different sums, and almost nobody does the sum.
Do the sum once
Find out what a local sharpener charges for one pair, and what the turnaround is. Then look at what a new pair of your working shears costs.
If sharpening is a third of replacement or less, and the shear holds an edge for months, sharpen. If sharpening approaches half of replacement and the shear dulls in weeks, you are paying a premium to keep a tool that was never going to hold. Replace.
The wrinkle is that a shear only takes so many sharpenings before the edge geometry is gone and it will not come back. So a premium shear sharpened twice a year for six years is a genuinely good deal, and a budget shear sharpened twice is money set on fire.
What a working set actually is
Not one pair. Five, and they do different jobs.
A straight shear for bulk work and legs. A curved shear, which is what does feet and rounds a head without you fighting it. A thinner or blender for softening a clipper line. A chunker for texture on a coat that shows every mark. And a small pair, five inches or so, for faces and paw pads, which is the one that saves you from nicking a wriggling dog.
If you are starting, buy the straight and the curved properly and let the other three be cheap. You will learn what you actually reach for within a month.
Left-handed shears are real
If you are left-handed, buy left-handed shears. Not right-handed ones held the other way.
The blade offset and the ride line are built for one hand. Using the wrong ones means the blades push apart under load instead of together, so you get fold rather than cut, and you compensate with grip pressure that goes straight into your thumb joint.
Australian trade suppliers stock left-handed shears. It is worth asking rather than assuming.
The long tail is a person, not a product
Here is the criterion that should decide your purchase, and it has nothing to do with steel.
Who sharpens it, where are they, and how long are you without the shear?
Several of the Australian trade suppliers run sharpening in-house rather than posting it away. Pupkus, Clipper World and Oz Grooming World all offer scissor and blade sharpening, and The Clipper Shop is a warranty and repair agent as well. There are also independents who work the trade directly, including Oz Clipper and Scissor and Mat's Sharpening Services.
Ask before you buy, not after. A shear you have to post interstate for three weeks is a shear you will stop using.
Care that costs nothing
Wipe them down at the end of every dog. Hair carries moisture and skin oil, and both eat an edge.
Put a drop of oil at the pivot weekly and open and close them a few times. That is it.
Never let anyone else use your shears, and never put them in a drawer loose. The two most common ways a good shear dies are a bench drop and someone borrowing it to cut a mat out of a matted dog.
What we would not buy
We would not buy a boxed set of eight shears at a single low price. There will be one usable pair in it.
We would not buy shears on hardness numbers. The steel spec on a listing is close to meaningless without knowing the heat treatment, and every seller quotes an impressive number.
And we would not buy an expensive pair as a first pair. Your grip, your angle and your preferences change enormously in the first two years. Buy well after you know what you like, not before.
What the internet gets wrong here
The budget shear brands that dominate American recommendations often are not distributed here, so the price advantage disappears once freight and the exchange rate land. Compare the Australian shelf price, not the US one.
And ignore anyone who tells you a premium shear does not need sharpening. Every shear needs sharpening. The difference is how long you get between visits.
