Curved vs Straight Shears: When to Use Each in Professional Grooming
Share
Every professional groomer has a preference — but the truth is, curved and straight shears aren't in competition. They're complementary tools, each designed to excel in specific situations. Understanding when to reach for each one will make you a more efficient, more precise groomer.
The Case for Straight Shears
Straight shears are the foundation of any grooming kit. Their flat, linear blade makes them ideal for creating clean, precise lines and working on flat surfaces of the coat.
Where straight shears excel:
- Body lines and toplines — creating a clean, level finish along the back and sides
- Leg columns — scissoring straight, cylindrical leg shapes on breeds like Poodles and Bichons
- Flat work — any area where you want a consistent, even length across a flat plane
- Precision trimming — detailed work where a predictable, straight cut is essential
Straight shears give you maximum control and predictability. When you need to know exactly where the blade will cut, straight is the answer.
In the UTSUMI JYO HINERI range: The straight variants are built for this precision work — delivering the clean lines that define a well-finished groom.
The Case for Curved Shears
Curved shears have a blade that arcs along its length, allowing the scissor to follow the natural contours of the dog's body without the groomer having to twist their wrist. This makes them faster, more ergonomic, and more natural for rounded shapes.
Where curved shears excel:
- Rounded shapes — the classic Poodle head, Bichon Frise round head, Bedlington topknot
- Hindquarters and angulation — following the curve of the stifle and hock on sporting breeds
- Ears and cheeks — creating soft, rounded shapes around the face
- Feet and paws — scissoring the rounded paw shape efficiently
- Any convex surface — wherever the coat follows a curve, a curved shear follows with it
The ergonomic benefit is significant too — curved shears reduce wrist rotation, which means less fatigue during a long grooming day.
In the UTSUMI JYO HINERI range: The curved variants are designed to follow body contours naturally, making rounded shapes faster and more consistent to achieve.

| Leg columns | ✓ Best | — |
| Round head (Poodle, Bichon) | — | ✓ Best |
| Hindquarter angulation | — | ✓ Best |
| Ear shaping | — | ✓ Best |
| Flat body work | ✓ Best | — |
| Paw rounding | — | ✓ Best |
| General scissoring | ✓ Good | ✓ Good |
Which Should You Buy First?
If you're building your scissor collection, start with a straight shear — it's the most versatile tool and handles the widest range of tasks. Once you're comfortable with your straight shear, adding a curved shear will dramatically speed up your rounded shape work and reduce hand fatigue.
Most professional groomers working on a variety of breeds will eventually want both. The combination of a quality straight and curved shear from the same range — like the UTSUMI JYO HINERI line — ensures consistent weight, balance, and cutting feel across both tools.
A Note on Curve Degree
Not all curved shears have the same degree of curve. A gentle curve is more versatile and easier to control; a more pronounced curve is faster for tight rounded shapes but requires more practice. UTSUMI's JYO HINERI curved shears are designed with a professional-grade curve that balances versatility with performance.
