Hammer Safety Tips
Strike squarely with the hammer striking face parallel with the surface being struck. Always avoid glancing blows and over and under strikes.
When striking another tool (chil, punch, wedge, etc.), the striking face of the proper hammer should have a diameter approximately 3/8" larger than the struck face of the tool.
Always u a hammer of suitable size and weight for the job. Don't u a tack hammer to drive a spike, nor a sledge to drive a tack.
Never u on hammer to strike another hammer or a hatchet.
Never u a striking or struck tool with loo or damaged handle.
Discard any striking or struck tool if tool shows dents, cracks, chips, mushrooming, or excessive wear.
Never regrind, weld or reheat-treat a hammer.

Pliers （钳子） Safety Tips
Pliers should not be ud for cutting hardened wire unless specifically manufactured for this purpo.
Never expo pliers to excessive heat. This may draw the temper and ruin the tool.
Always cut at right angles. Never rock from side to side or bend the wire back and forth against the cutting edges.
Don't bend stiff wire with light pliers. Needle no pliers can be damaged by using the tips to bend too large a wire. U a sturdier tool.
Never u pliers as a hammer nor hammer on the handles. They may crack or break, or edges may be nicked by such abu.
Never extend the length of handles to cure greater leverage. U a larger pair of pliers or a bolt cutter.
Pliers should not be ud on nuts or bolts. A wrench will do the job better and with less risk of damage to the fastener.
Oil pliers occasionally. A drop of oil at the hinge will lengthen tool life and assure easy operation.
Safety glass or goggles should be worn when cutting wire, etc. to protect eyes.
