Evidence limitations
We do not claim completed bench testing, long-term durability trials, or guaranteed movement safety.
Review Policy
Our reviews compare listing quality and task fit, not lab-confirmed tool performance.
| Criterion | What we look for | Evidence limit |
|---|---|---|
| Tip precision vs movement needs | Declared widths such as 0.80mm, 1.20mm and stated target use | Seller-stated dimensions may be inconsistent |
| Alloy and scratch risk | Material terms and hardness wording, including claims like 54 HRC | Claims are not treated as verified metallurgy |
| Single tools vs kits | Included accessories, duplicates, and missing essentials | Bundle photos and text may not fully match |
| Seller listing clarity | Variant labeling, unit consistency, and compatibility notes | Unclear listings are flagged, not guessed |
Metadata requirement
Any affiliate recommendation must include target task and compatibility metadata, including relevant tip width or dimensional fit.
