Left-Handed Thinning Scissors: 14 Options Compared
Which thinning scissors come in a true left-handed build? Fourteen options compared by size, listed tooth count and handle, from Mina, Ichiro and Kamisori.
On this page
Only two Japanese brands in our range, Mina and Ichiro, build a thinning scissor for the left hand: seven options between them. Six are 6.0-inch tools only; Mina Rainbow II comes in 5.5 and 6.0 inches.
Kamisori, a Canadian brand with Japanese-inspired designs, adds seven more at higher prices. In every case, choose “Left” in the selector before you add to cart.
How this list was made
We went through all 62 thinning and texturising products in the JapanShears product records and kept the ones that list a left-handed build. Fourteen do. We compared each record’s hand option, size, listed tooth count, steel field and handle on 3 November 2026. We did not test any of them; this is a comparison of listings, not a hands-on review.
The order is by brand, then by price on that date. It is not a ranking. Each card shows the selected option and its current price from the product record, so check the option before you order.
Our relationship to these products
JapanShears sells every product below, and every link goes to our own product page. Mina and Ichiro are independent Japanese brands, not JapanShears brands. JapanShears is a member of the ShearAlliance and is run by the same seller as four other Australian ShearAlliance stores. Our editorial policy explains how we compare products and why a numbered list is not a test result.
Compare the options
| Thinner | Left option | Teeth listed |
|---|---|---|
| Mina Rainbow II | 5.5 or 6.0 in | 30 |
| Mina Umi | 6.0 in | 30 |
| Mina Jay II | 6.0 in | 30 |
| Ichiro Rose Lefty | 6.0 in | 30 |
| Ichiro Pink Moon | 6.0 in | Not listed |
| Ichiro Rose Gold | 6.0 in | 30 |
| Ichiro Matte Black | 6.0 in | Not listed |
Mina: three left-handed thinners at one tooth count
All three Mina thinners list 30 V-shaped teeth, an offset handle and SUS440C steel. The differences are size, finish and the cutter they sit beside, so decide those first.
1. Mina Rainbow II: the only left-handed thinner with two lengths
Suits: a left-handed stylist who wants a 5.5-inch thinner to sit beside a 5.5-inch cutter. Deciding field: the 5.5 and 6.0-inch left-handed options. Trade-off: it is the one to pick for length, not for any other listed difference, because its tooth count and steel match Umi and Jay II. Match the length to your cutter, and read the length from the selector label on the product page rather than from the SKU.
2. Mina Umi: the thinner that matches the Umi cutter family
Suits: someone already using, or buying, a left-handed Umi cutter. Deciding fields: 6.0 inches, 30 V-shaped teeth, a mirror-polished finish and a key-adjustable screw. Trade-off: one length only, so a 5.5-inch kit needs a different thinner.
3. Mina Jay II: the satin finish
Suits: a left-handed buyer who wants a satin finish rather than Umi’s mirror polish. Deciding fields: 6.0 inches, 30 V-shaped teeth, SUS440C steel. Trade-off: it is the same tooth count and size as Umi, so choose between them on finish and on the cutter you are pairing it with. The Jay II pair combines a cutter with this thinner.
Ichiro: four left-handed thinners
4. Ichiro Rose Lefty: built for the left hand and sold that way
Suits: a left-handed buyer who wants one fixed 6.0-inch tool with no handedness choice to get wrong. Deciding fields: 30 V-shaped teeth, offset handle, left-handed only. Trade-off: it has no right-handed twin on the page, and it sits at a higher price than the Mina options. The Rose Lefty two-piece kit pairs the cutter with this thinner.
5. Ichiro Pink Moon: 440C steel, tooth count not listed
Suits: a buyer matching the Pink Moon cutter finish. Deciding fields: 6.0 inches, 440C steel, V-shaped teeth, Right and Left variants. Trade-off: the record gives no tooth count, so you cannot compare it with the 30-tooth tools above on that field. Ask us before ordering if the count matters to you.
6. Ichiro Rose Gold: 30 teeth, and a Right or Left choice
Suits: someone who wants a listed 30-tooth count in an Ichiro finish. Deciding fields: 6.0 inches, 30 teeth, offset handle and spring-loaded pivot. Trade-off: the steel field reads only “stainless-steel”, so there is no grade to compare.
7. Ichiro Matte Black: a dark finish with 440C steel
Suits: a buyer who wants a dark finish and a named steel. Deciding fields: 6.0 inches, 440C steel, V-shaped teeth, separate Right and Left builds. Trade-off: no tooth count is listed, so it cannot be compared with Rose Gold on that field.
Kamisori: seven more, at higher prices
Kamisori is a Canadian brand with Japanese-inspired designs; some models are made in Japan. Its seven left-handed thinners suit a buyer who already knows the Kamisori range. Six list 6.0 inches and 30 teeth; the Sword is 6.5 inches with no tooth count listed. Each link below opens the left-handed option.
| Kamisori thinner | Note from the record |
|---|---|
| Diablo II | 30 teeth, Takefu cobalt alloy stated |
| Black Diamond III | 30 teeth, VG-10 steel listed |
| Jewel III | 30 teeth, fixed offset handle |
| Jewel III Double Swivel | 30 teeth, both rings swivel |
| Sword | 6.5 in, ATS-314 listed, count not listed |
| Revolver III | 30 teeth, double-swivel handle |
| Diamond | 30 teeth, ATS-314 alloy listed |
The table runs from the lowest to the highest price on 3 November 2026; the product pages show the current price for each option.
What you will not find
No Joewell, Yasaka, Kasho or Juntetsu thinner in our records has a left-handed option. Those makers’ left-handed listings are cutters, so a left-handed kit built around them needs a thinner from Mina, Ichiro or Kamisori. See the left-handed cutter shortlist for the cutter side.

- Its mirrorThe ring, shank and blade arrangement is mirrored together. Turning the first tool over in your grip does not rebuild it.
What would change this list
A new left-handed thinner from another maker, or a change to a tooth count or hand option in a record, would alter it. If you are unsure about the thinner at all, a pair listing may suit you better than two singles: compare the left-handed collection. For right-handed thinners under a set budget, see the thinning scissors under A$300 comparison.
Before you order
- Pick “Left” in the selector, then check the SKU in the cart. A right-handed shear used in the left hand is a different tool, not a mirrored one: the handed-build guide shows why.
- A tooth count is not a cut ratio. Thirty teeth on two tools can remove different amounts, because tooth shape and spacing also matter. Joewell’s thinning manual explains both factors, and our cut-ratio guide shows real model figures.
- Not sure thinning is the job? Read the thinning and texturising shortlist, which covers higher-priced right-handed models, and the anatomy guide.
