A genuine left-handed thinner that performs far above expectations. Built left from the start on Japanese Cobalt Alloy, it blends clean and seamless for left-handed stylists who’ve had to make do — finally, a thinner that fits.
It blends so cleanly the work looks like it was never thinned — soft, seamless, exactly as much as you asked for and not a hair more. The kind of finish that looks expensive.
From Matt Grumley, Australian scissorsmith: “Left-handed stylists deserve real tools. I build these properly left — soft, clean, true.”

What that means at the chair
- Cobalt alloy steel at 58 HRC — tough enough to hold its edge through daily salon blending without being brittle or fussy to maintain
- 6030 straight blade with 30 teeth — takes out even, predictable amounts of bulk each closure, so the blend stays soft and you stay in control
- Offset ergonomic handle built genuinely left-handed — your wrist and thumb sit naturally instead of fighting a converted right-hander all day
- Single bearing flat tension system — the blades stay set where you put them, so every pass cuts the same as the last
Who it’s not for: If you're right-handed, this isn't your thinner — it's built properly left from the ground up, so grab the standard Young Genius thinner instead.
A first professional thinner, built genuinely left
Left-handed apprentices usually inherit the worst tools in the salon — flipped right-handers that teach bad habits from day one. This thinner is the correction: built left from the start, 30-tooth Cobalt Alloy blade at 58 HRC, left-built offset ergonomic handle, $250. Professional properties at an honest price, and a tool that stays on the trolley for years of everyday blending — not something you replace the moment you qualify. Covered for life against manufacturing defects.
Match it with the Young Genius left-handed cutting scissor ($250) — or get the matched pair in the left-handed scissor and thinner set ($350). Everything else for a first kit is in the Apprentice Range.
