hammer and screwdriver

Piece counts vary widely. Examples range from small 9–16 piece kits to mid-size 39–62 piece sets and larger 108–135 piece collections.

Common additions include pliers, tape measures, utility knives, adjustable wrenches, hex/Allen keys, scissors, socket sets, levels, putty knives and precision screwdrivers.

Sizes and weights vary by kit. Weight examples range from about 2.25–3.3 pounds for compact sets up to roughly 6–9 pounds for larger kits. Case dimensions in the examples run from about 1.0 × 7.7 × 10.2 inches to roughly 3.5 × 11.02 × 15.5 inches.

Some kits include cordless powered drivers that require or recommend batteries (e.g., cordless drills or screwdrivers). Many other kits are hand-tool only and list "Battery: No Battery Used."

Common features include thickened handles, TPR (non‑slip) material and contoured comfort grips to improve hold and reduce user fatigue.
