Overview
The RM-SK is an alloy steel hand tool weighing about 0.24 kilograms (8.5 ounces). The listing brand field simply reads Japanese, and the category is a general tools grouping, so treat the exact use as unconfirmed beyond the material and weight given.
Alloy steel is a common choice for hand tools that need a balance of hardness and toughness, more resistant to chipping than plain carbon steel in some formulations. Beyond that, this listing does not break out handle material, length or a specific function.
