Tokyo Riki names ALU-COBA as one of its scissor lines in its company history. That history dates the company, not the launch of ALU-COBA. The current line catalogue explains the name through its aluminium handles and cobalt blades. It gives a construction distinction you can actually compare; it does not identify one precise cobalt alloy or promise a particular edge life across the line.
The catalogue separates the AC and ACM cutters from ACH thinners. For a specific cutter, the ACM-60 sheet lists a 6-inch size, 73 mm cutting blade and 38 g weight. That is a model measurement, not proof every ALU-COBA feels lighter than every steel-handled shear. The ACH-30T catalogue entry is a 6.25-inch thinner with an approximately 30% maker cut-rate figure. A thinner’s actual removal depends on hair, section and use; compare its tooth design with the finish you want rather than treating the percentage as a guarantee.
Confirm the full AC/ACM/ACH model code, length, hand configuration and the source of replacement parts or sharpening. The maker’s Japanese catalogue prices are local listings, not a verified price for your market. If buying through the retailer links here, ask that seller for current stock, returns and service terms. The cobalt-alloy guide explains why the material label alone does not establish finished cutting behavior.
Tokyo Riki lists ALU-COBA among its own lines. The company’s history is not a launch date for this particular line.
The maker catalogue describes aluminium handles and cobalt blades. It does not name a precise alloy grade for every model.
The ACH-30T entry is 6.25 inches with an approximate 30% maker cut-rate claim. Check the unit and technique before relying on that percentage.
