Knife Tools Scoring Standards

Knife Tools Scoring Dimensions

The highest weights are assigned to complaint avoidance and durability, as over 90% of negative reviews for knife tools relate to common defects (rust, breakage) and long-term performance issues (poor edge retention). Authentic praise for core features is next in importance, while recommendation rate is given the lowest weight as it is a secondary, holistic satisfaction signal.

Weight Distribution

Dimension	Weight	What It Means
Complaint Avoidance	30%	Lower complaint rate → higher score
Authentic Praise	20%	More specific praise → higher score
Durability	35%	Better long-term reliability → higher score
Would Recommend	15%	Higher “would buy again” rate → higher score
