Overview
High carbon steel and a plastic handle make up this compact knife, 5.1 inches overall and under 2 ounces, sized for everyday small cutting tasks rather than heavy outdoor use.
High carbon steel takes and holds a sharp edge well but is more prone to rust than stainless without regular wiping and occasional light oiling, a tradeoff worth knowing before it goes anywhere damp. The plastic handle keeps total weight to 1.8 ounces, light enough to carry daily without noticing it. No blade length is broken out separately from the 5.1 inch overall figure, so the exact cutting edge is not confirmed.
- High carbon steel blade
- Plastic handle
- 5.1 inch overall length
- 1.8 ounce weight
Who it's for
Suited to someone who wants a light, low cost knife for everyday small cutting tasks. Not the choice for heavy outdoor or survival use, where a thicker or stainless blade holds up better to moisture.
Strengths and trade-offs
Drawn from this product's published specifications.
- Under 2 ounces, easy to carry daily
- High carbon steel takes a sharp edge
- Carbon steel needs drying and oiling to avoid rust
- Plastic handle rather than a more durable material
- Blade length not broken out from the 5.1 inch overall measurement
Performance notes
High carbon steel sharpens to a fine edge and holds it through moderate use, but it lacks the chromium content that lets stainless steel resist corrosion, so the blade needs drying after use and a light coat of oil for storage.
