Ninja’s history says it has designed and produced hairdressing scissors since 1999. Its current contact page lists Birmingham, England, plus US and European contacts. Those addresses locate sales and service; they do not tell you where every model was manufactured. The maker describes Japanese-steel construction, but the useful buying question is the specific blade and hand you need.
The SAI Lefty is a left-hand cutter described as forged 440C, with a convex edge and offset handle. The Crocodile Lefty is a 6-inch, 30-tooth thinner, also listed as 440C. Ninja gives that thinner a 20–25% cut rate. Treat that number as a maker estimate for the named model: hair section, stroke and technique change how much is removed in use.
A cutter and a thinner are not substitutes. Decide whether the next task is establishing a clean line or reducing density, then select the correct left-hand blade. The thinning guide explains why tooth count alone is not a reliable removal formula.
Ninja’s warranty page covers manufacturing defects for the product lifetime and excludes normal wear, misuse, improper maintenance and unauthorised repair. Its product FAQ also points buyers to registration. Check that requirement and the seller’s terms before ordering. An offset handle or rotating feature is a design choice, not a medical outcome; compare the model in your own cutting grip if possible.
The maker lists a Birmingham UK contact alongside US and European contacts. The directory country is a business grouping; the office addresses do not establish every model’s manufacturing origin.
The SAI Lefty is a 440C cutting shear. The Crocodile Lefty is a 6-inch, 30-tooth 440C thinner with a maker-listed 20–25% cut rate.
No. The warranty page covers manufacturing defects and excludes normal wear, misuse, improper maintenance and unauthorised repair. Confirm registration and current purchase terms with the seller.
