Mastercut ‘Signature’ Professional Dog Grooming Scissors (50 Teeth Blending – Convex, Serrated Blades)

Professional dog grooming scissors are essential tools for pet styling but, with so many different types to choose from, which one is right for you.  If you’re aiming to work with pure ‘scissored’ breeds, we highly recommend investing in scissors that have ‘convex’ blades.  These are the sharpest and most accurate cutting, enabling you to produce cleaner lines and contours.  Whether you’re creating cylindrical legs, enhancing angulation, perfecting head styles or just thinning and blending the coat, Mastercut offers a comprehensive range of designs to help you achieve your best work.

Blenders vs thinners.

If you’re wondering what the difference is, allow us to explain.  Use blending scissors to smooth out imperfections and transition between different lengths of coat.  Alternatively, use thinning scissors to remove bulk and change the texture of thicker hair, making it easier to style and manage.  You can quickly tell the difference simply by looking at their blades.  Thinners have teeth on both blades, whilst blenders combine a straight cutting edge.  Tooth design can vary slightly, according to length, width, spacing and finish.  This ultimately determines the amount of hair the scissor will remove and, multiple cuts may prove necessary to achieve the desired look.

Features and benefits.

This scissor measures 7″ (about 18cm) in length.  The blending blade has 50 teeth, which are radial-cut to create more natural looking coat texture.  Each tooth has a notch to grip and control the hair whilst cutting.  Due to the high number of teeth, this scissor is ‘fine’ cutting and, will remove approximately 45% of the hair with each cut.

Specific features include:
Materials: 440C stainless steel, to protect against metal corrosion.
Blades: Fine radial-cut teeth to create softer, more natural texture.
Tensioning: Pivot screw dial for quick and easy adjustment.
Leaf-Spring: Distributes tension evenly along the cutting blades.
Ball-Bearing: Stabilises the blades and offers noticeably smoother cutting action.
Teflon Glide: Improves wear resistance and the working life of the scissor.

How do I use them?

The off-set handle style design encourages a more comfortable open-hand grip, using the ring finger and thumb.  This handle style features shorter shanks to improve handling and prevent over extension, which can cause repetitive strain injuries.  Once inserted through the finger rings, operate the scissor using just your thumb to smoothly open and close the cutting blades.  Unless you’re removing bulk and creating basic shape, always remove the hair in small amounts to avoid mistakes and stepped changes in hair length.

What else should I know?

Convex blades are incredibly sharp but, equally delicate and easy to damage if not appropriately handled.  Before you start scissoring, the most important thing to check is the tension between the cutting blades.  This must be set correctly in order to prevent accidental damage.  If the tension is set too low (loose), the cutting blades will inevitably grind together, spoiling their delicate cutting edge with nicks and indentations.  Setting the tension high (tight) can be equally damaging, as this will encourage you to apply more lateral force, increasing the chance and risk of twisting and catching the blades.  If this happens, resharpening is usually the only way to reverse the damage.
Whilst this demand for accurate tension may seem like a design fault, in truth it is more a case of acknowledging and understanding the needs of this precision cutting instrument.  For the first few weeks of use, we recommend checking the tension every time you use the scissor.  Once moving parts have settled for normal working life, the scissor will require less attention.

A few final words of advice.

Like other precision cutting instruments, convex scissors demand suitable care and attention to keep them in good working order.  As such, we recommend the following:

  • Avoid using convex scissors on dirty or greasy coats.  These can harbor fine particles and contaminates, which act just like abrasives and can quickly dull the cutting blades.
  • To help create volume and structure in the coat, consider using a scissoring spray.  This will help you attain sharper lines, smoother contours and crisp texture.
  • Always clean and oil your scissors after use and, consider storing them a protective sheath or wallet to avoid damaging your equipment.

Tensioning: Every ‘elite’ scissor is accurately tensioned for optimal cutting performance. However, fine adjustments are often necessary, as the blades settle for future working life. Adjusting the tension is important to prolong blade life and ensure comfortable handling. To that end, these scissors are fitted with tension-adjustable screws for quick and easy use. More information about this task is explained in detail here.

Sizing: There are a couple of different approaches to measuring scissors, depending on whether the finger rest (tang) is removeable or an integral part of the scissor. If it’s integral, it is generally included in the overall length of the scissor, otherwise measurement begins from the tip of finger hole.

Keeping your scissors in good working order is essential to prolong their working life and maintain optimum cutting performance. Simplistic maintenance is all that’s needed, requiring only a few minutes each day, to ensure moving parts are clean and lubricated. This is particularly important for scissors made from carbon steel, which are more susceptible to corrosion if left neglected in warm, humid conditions.

Correctly storing your scissors is equally important to prevent accidental damage. Consider using a dedicated scissor pouch or wallet and resist temptation to place them loose in a drawer or toolbox, where searching for tools may cause unecessary wear and tear.
