Key specifications

• Form factor: folding utility knife with a single blade
• Primary use: everyday cutting and light outdoor tasks
• Portability: compact size suitable for pocket or kit carry
• Safety: blade stows within handle when folded
• Maintenance: single-blade design for straightforward cleaning and blade changes

How to use

Open the knife by unfolding the blade until the locking mechanism engages to ensure the blade remains secure during use. Hold the handle firmly and use controlled, steady cuts appropriate to the material being cut. After use, carefully fold the blade back into the handle until it is fully stowed; ensure fingers are clear of the blade path when closing. Regularly clean the blade and pivot area to remove debris and moisture, and dry thoroughly before storage to reduce corrosion risk.

Usage recommendations

Use the knife for appropriate tasks within its intended scope: light cutting, trimming, and general-purpose outdoor activities. Avoid prying, twisting, or heavy-duty cutting that could damage the blade or folding mechanism. Store the knife folded and out of reach of children. For longer blade life, keep the blade clean and dry and replace or sharpen it when performance declines.
