Multi-tool blade steels compared: 420HC vs D2 vs 154CM vs MagnaCut on hardness, edge retention, toughness, corrosion resistance and field sharpening.
Surgical hardware maintenance requires absolute bit tolerances and static-safe handling handles. We compare the precision driver packages from iFixit, Wera, and Wiha.
A reliable multitool is the foundation of any field repair kit. We strip away marketing claims and analyze the steel formulas, locking kinematics, and tool layouts of Leatherman, Roxon, and Gerber.
