Overview
A carbon steel utility knife with a plastic and steel handle. The 18 millimeter measurement matches standard snap off utility blade width, not a fixed blade length.
Listed under Tools rather than kitchen cutlery, and with an 18mm figure that lines up with the industry standard snap off blade size, this reads as a utility or box cutter rather than an everyday carry or kitchen knife. The category label just says Knife, so title and the 18mm spec are the more reliable guide.
- Carbon steel blade
- Plastic and steel handle construction
- 18 millimeter blade width
- Amartisan brand utility knife
Who it's for
Suits anyone needing a utility knife for cutting boxes, drywall or carpet, where a standard 18mm snap off blade is the norm. Not the pick for buyers searching for a kitchen or fixed length pocket knife.
Strengths and trade-offs
Drawn from this product's published specifications.
- Standard 18mm blade width common to most snap off blade refills
- Steel reinforced handle for grip durability
- Carbon steel blade takes a sharp edge
- Carbon steel needs drying to avoid rust
- Plastic handle component is less rugged than an all metal body
Performance notes
Carbon steel holds an edge well but is more prone to rust than stainless if left wet, so it rewards a quick wipe down after use in damp conditions.
