The Andis UltraEdge 7 Skip Tooth (7ST) is a specialized blade designed primarily for heavy-duty grooming, particularly when you are dealing with thick, matted, or “tough” coats.
Here is a breakdown of what makes this specific blade unique and how to use it safely.
Key Specifications
-
Cutting Length: 1/8″ (3.2mm).
-
Blade Type: Skip Tooth (not a “finish” blade).
-
Material: Carburized steel with a chrome finish to resist rust.
-
Compatibility: Fits all Andis AG, AGC, BDC, BG, DBLC, FHC, MBG, and SMC model clippers (as well as Oster A5 and Wahl KM series).
Why Use a “Skip Tooth” Blade?
Unlike “Finish” blades (labeled with an ‘F’), where all the teeth are the same length, a Skip Tooth blade has alternating long and short teeth.
-
Better Feed: The uneven teeth help “comb” thick or wiry hair into the cutting blade. Its much more effective at feeding coarse fur than a smooth finish blade.
-
Matted Fur: It is often the “go-to” for prep work on dogs with heavy coats (like Terriers or Spaniels) before the bath.
-
The Finish: Because the teeth are uneven, it leaves a more natural, textured look. If you want a perfectly smooth, velvet finish, you would typically follow this up with a 7F (Finish) blade.
Essential Safety Warning
Skip Tooth blades require a steady hand. Because the teeth are spaced further apart, it is much easier for a pets skinespecially thin skin or foldsto get caught between the teeth and be nicked.
Pro Tip: Never use a Skip Tooth blade on cats or in sensitive areas (like the “armpits” or tuck-up) where the skin is loose. Stick to “Finish” blades for those areas.
Maintenance for Longevity
To keep the blade from dragging or pulling hair:
-
Oil Frequently: Apply 3 drops of clipper oil across the teeth every 15 minutes of use.
-
Clean the “Gills”: Because it feeds a lot of hair, hair can get trapped between the top and bottom blade quickly. Use a blade brush or “Blade Wash” regularly.
-
Check the Heat: Skip Tooth blades can friction-heat quickly. Touch the blade to your forearm frequently; if it’s uncomfortable for you, it’s too hot for the dog.
