Overview
An 8.63 inch stainless steel knife weighing about 1 ounce, listed under OLFA's tools lineup. The light weight and slim build point to a utility or craft knife rather than a heavy duty blade.
OLFA built its reputation on utility and craft knives rather than kitchen cutlery. The 1 ounce weight here is far lighter than a comparable fixed kitchen knife of the same 8.63 inch length, which fits a slim bodied utility or hobby knife instead.

Who it's for
Works for craft, hobby or light utility cutting where a slim stainless body is easy to grip for detail work. Less suited to heavy cutting tasks that call for a thicker, heavier blade.
Strengths and trade-offs
Drawn from this product's published specifications.
- Stainless steel resists rust with little upkeep
- Light 1 ounce weight for extended handheld use
- 8.63 inch length gives reach for detail cuts
- Light build is not suited to heavy cutting loads
Performance notes
Stainless steel resists corrosion better than carbon steel, a common OLFA tradeoff for buyers who want lower upkeep over the sharpest possible edge retention.
